One of the greatest challenges in mammalian systematics is the Thomomys bottae-umbrinus complex, with its approximately 225 described subspecies. As part of a taxonomic investigation of the lice from these gophers we have accumulated and mounted over 31,000 adult lice from 2,000 hosts representing over 1,000 localities, and have quantified over 300,000 character observations from more than 11,000 of these lice. These character observations combined with their host and locality information form a computerized data base which is maintained at the University of Minnesota. Because of the quantity and complexity of these data we have automated our data handling and analysis and some portions of the taxonomic decision making process. We have developed an integrated group of computer p r og rams called the BUG system which is used for the retrieval and analysis of stored louse data. This system provides for the definition of tentative taxonomic louse groups, the extraction of data for lice within these groups, and the analysis or comparison of these data within a group or between groups. Group definitions may be based on preliminary louse identification, host identification, host locality specific host, or specific louse, or any combination of these criteria. The kinds of analyses built into the system include general data summarization, character correlations, analysis of variance, principal components analysis, and agglomerative clustering. The system also has some graphics capabilities,including character distribution graphs, principal components scattergrams, and host geographic distribution maps. It can also select and format- louse data for use with general statistical analysis computer program packages such as the BMD-Biomedical Computer Programs. The system is used to evaluate character homogeneity within groups of lice, make comparisons between groups and identify taxonomically useful characters for descriptions. Criteria for taxonomic groupings were developed from a comprehensive study of louse variation using a 5-level nested analysis of variance model. We have delineated 25 new louse taxa so far during this study and it is likely that more will be found.

The collections of chewing lice studied by Kellogg \& Paine, 1914 were damaged or lost in R. Varuna floods at Varanasi during 1944, when the Zoological Survey of India collection was housed there during the II World War. During a recent study by the first author of the type collections available in the department, the type slide of Colpocephalum thoracicum Kellogg \& Paine, was found without the coverslip or specimen. This species was found by the second author to be a valid one and was\&$\#$39; redescribed from the material available to him. Recently, material in the British Museum (Natural History), London, was also examine d by the authors and the neotype and neoparatype are now designated in this paper. Some remarks on the distribution of the species and host relationship are also provided.

A revision was undertaken of the members of the genus Geomydoecus parasitizing Plains Pocket Gophers of the Geomys bursarius complex. Prior to this revision, 5 specific and subspecific taxa of lice were recognized from Geomys bursarius. Approximately 20,000 lice were obtained and examined; these were from all described subspecies of G. bursarius and represented 590 individual hosts from 427 localities. In addition to a study of qualitative features, 28 morphological characters were quantified for both adult male and female lice. The measured or counted characters that proved useful taxonomically are reported along with their ranges, means, and standard deviations. Three programs in the BMDP series were used for the multivariate statistical analysis: principal components analysis (BMDP4M), discriminant function analysis (BMDP7M), and cluster analysis (BMDP2M). The Geomydoecus on Geomys bursarius proved to be quite variable geographically; however, there was little intrapopulation variability. This geographical variation is best represented taxonomically by recognizing 8 distinct monotypic species of lice. The previously described species, Geomydoecus geomydis, G. ewingi, G. illinoensis, and G. oklahomensis, are all recognized as valid species. A population previously described as a subspecies of G. geomydis is elevated to specific status, G. .subgeomydis, and 3 new species are described: G. heaneyi on Geomys bursarius llanensis and G. b. texensis; G. nebrathkensis on Geomys bursarius lutescens; and G. spickai on Geomys bursarius missouriensis. These 8 species of lice cluster as 2 distinct groupings: the 1st, here termed the \"northern\" group, is composed of\&$\#$39; G. geomydis, G. illinoensis, G. nebrathkensis, G. oklahomensis, and G. spickai; the 2nd, the \"southern\" group, is composed of G. ewingi, G. heaneyi, and G. subgeomydis. In no case did a single population of pocket gophers have more than 1 species of Geomydoecus parasitizing it. Two species of Geomydoecus were obtained on Long-tailed Weasels, Mustela frenata; these host records are considered primary contamination, a result of the weasel\&$\#$39;s obtaining the lice directly from pocket gophers. A key is presented to the 15 specific and subspecific taxa of Geomydoecus that parasitize pocket gophers of the genus Geomys.

Geomydoecus subcalifornicus is redescribed and illustrated; its known host range is 44 subspecies o f Thomomys bottae and 3 of T. umbrinus from U.S.A. (Arizona, California, Nevada, Utah) and Mexico (Baja California, Sonora). A new species, G. guadalupensis, is described from 5 subspecies of T. bottae (type-host : T. b. guadllupensis ) from U.S.A. (New Mexico, Texas) and Mexico (Coahuila). Quantitative characters of these lice, together with their host and locality data, were stored and evaluated by a computerized taxonomic analysis system. This was used to: define and identify tentative taxonomic groups; evaluate these groups for homogeneity; make comparisons among groups; and produce preliminary descriptions, lists of material examined, and host geographic range maps. Distinctions among tax a are shown using qualitative and quantitative characters and principal components analysis of quantitative characters.
