The species ranges from British Columbia to Lower California and 

 far into Mexico. 



G. politus, new species. 



Similar in form to nitiJns but smaller. ISody entirely black, highly polished 

 above, usually with distinct greenish tinge ; rarely obscurely suffused with testaceous, 

 especially toward the base of the elytra ; legs and base of antenna; testaceous. Pro- 

 thorax rather feebly narrowed posteriorly, the sides sinuate before the hind angles 

 which are nearly right. Sides with a single marginal seta just before the apical third ; 

 basal impressions rather broad and with a few punctures. Elytral stria; except the 

 sutural, faint or obliterated. Lower surface except the prosternal side pieces sparsely 

 punctate, each puncture bearing a short hair ; ventral surface finely but distinctly 

 alutaceous, shining; pubescent spots in the male distinctly separated. Length 3.5 

 to 5 mm. 



( >regon (The Dalles) to southern California. A rather common 

 species which has hitherto been unaccountably confused with nitidus. 

 It is evidently this species which Dr. Hamilton referred to as "the 

 small form" in his Random Notes on Coleoptera (Ent. News, 1896, 

 p. 291) where he says of Tachycellus nitidus, " Scarcely a species in 

 the whole range of Coleoptera exhibits greater diversity among the 

 individuals in size and color, varying from .14 to .2S inch in length 

 and from bronzed black to testaceous. According to Dr. Horn the 

 small form which is the black one is usually the male, while the larger 

 testaceous individuals are mostly females." It is needless to say that 

 the statement quoted is entirely misleading. 



G. intermedius, new species. 



Black, highly polished, with distinct bronze or green bronze surface lustre ; 

 base of antennas and legs pale. Prothorax more distinctly narrowed behind than in 

 politus, sides slightly sinuate before the hind angles, which are plainly obtuse though 

 sharply defined ; basal impressions with very few tine punctures. Otherwise nearly as 

 in politus. Length 4. 2-4.5 mm - 



California. Described from three females, two of which (the 

 types) were taken by me in the San Bernardino Mts., the third by Dr. 

 Fenyes at Lake Tahoe. It is assumed in the table that the abdominal 

 pubescent spots are as in obtusus. 



G. obtusus, new species. 



Differs from intermedius in its more obtuse hind angles of the prothorax, the side 

 margins not or scarcely sinuate before them ; also in the relatively shorter elytra, as 

 indicated in the table. The abdominal pubescent spots in the male are contiguous. 

 Length 3.5-4 mm. 



Southern California (Pasadena, Azusa, Claremont). Our smallest 

 species. Thus far it has been taken only in the valleys at elevations
