the length of the body, rather more slender than in badiipc'iinis ; pubescence begin- 

 ning at the middle of the third joint. Prothorax moderately transverse, widest 

 before the middle ; sides arcuately converging to base which is slightly wider than 

 the apex ; base angles obtuse, scarcely rounded ; median line fine and complete ; 

 basal impressions broad with about eight minute punctures at the bottom of each im- 

 pression. Surface otherwise impunctate. Elytra two fifths wider than the pro- 

 thorax and seven tenths as wide as long; stri?e fine, impunctate, intervals flat; apex 

 rather strongly sinuate. Front and middle tarsi broadly dilated in the male, the 

 fourth joint emarginate. Length 5.5 mm., width 2.5 mm.

Described from two examples (rJ'Q) collected at Beulah (8,000 

 ft.), and Cloudcroft (9,000 ft.) by Cockerell and Knaus respectively. 



As the genera are at present defined this species will prove a disturb- 

 ing element wherever placed. The third joint of the antennas being 

 pubescent in apical half would, strictly speaking, exclude it from 

 Tachxcellus, but the same is true of nigrinus which has long occupied 

 a place in the genus. Th'e middle tarsi are nearly as widely dilated 

 as the front ones in the male of turbatus, but much less so in typical 

 Tachycellus. Turbatus cannot, however, be included in Stenolophus 

 because of the toothed mentum and non-bilobed fourth tarsal joint, 

 nor can it be referred to Bradycellus because of the squamose inter- 

 mediate male tarsi. Of the species now referred to Tachycellus, 

 turbatus most resembles badiipennis, though distinctly more robust. 



Genus GLYCERIUS Casey. 



This genus was established by Casey for the Acupalpus nitidus of 

 Dejean, subsequently referred to Bradycellus by Mannerheim and 

 LeConte, and to Taciiycellus by Horn. The species represent a well 

 marked type, differing conspicuously in facies and in combination of 

 structural details from any of the genera with which it has been asso- 

 ciated, and notwithstanding its rejection by Horn, the genus appears 

 to me to be well founded. In Casey's short diagnosis much stress is 

 laid upon the numerous marginal setae of the prothorax. The char- 

 acter is indeed a remarkable one but it possesses absolutely no weight 

 from a generic standpoint, there being only the normal single seta 

 each side in each of the new species described below, all of which are 

 certainly congeneric with nitidus. Briefly the principal characters of 

 the genus are as follows : 



Mentum toothed ; front tarsi ( $ ) rather feebly dilated and biseriately squamu- 

 lose, middle tarsi undilated and without squamules ; antennae with three glabrous
