Head pale throughout; elytral vestiture short, eveu, dense and pale cinere- 

 ous over the entire surface 5. rilficollis 



Head blackish toward base; elytral vestiture longer, sparse and dark in 

 color, becoming cinereous near the apex and toward the humeri. 



G. bicolor 



In geographical range these species occup}* the same regions as 

 Dasytes, but at present none is known to extend far to the east- 

 ward of the Sierra Nevada Mountains.

(Dasytes). 



Elongate, suboval, rather convex, polished, black ; legs rufous, 

 the femora piceous ; antennte black, piceous toward base ; pubes- 

 cence rather sparse and somewhat short, cinereous, decumbent 

 and completel}' devoid of erect hairs. Head about three-fifths 

 as wide as the prothorax, smooth, finely- and sparseh' punctate, 

 more closely so and slightly rugose toward the sides and base ; 

 opistoma very short, the labrum arcuato-truncate at apex ; eyes 

 small and convex ; antennte rather short, slender, the penul- 

 timate joints apparently slightly transverse. Prothorax nearly 

 four-fifths wider than long, the sides parallel and distinctly arcu- 

 ate, rather more strongly so behind the middle, the edge distinctlj' 

 serrulate ; basal angles broad}' rounded, the apical obtuse but not 

 rounded from above ; apex and base equal, the former truncate, 

 the latter broadl}' arcuate ; disk finely, sparsely punctate, more 

 closely so but not rugose toward the sides, where the surface be- 

 comes broadly subexplanate ; marginal fringe verj' short but 

 dense. Elytra two-fifths longer than wide, scarcel}' more than 

 one-foui'th wider than the prothorax, very slightly wider near api- 

 cal third than at base, the apex somewhat obliquely narrowed, 

 then narrowl}' obtuse and rounded ; disk finely, not very densely 

 punctate, strongly so toward base. Length 1.6 mm.; width 0.15 

 mm. 



California (Sta. Catalina Island). The broadly subexplanate 

 sides of the pronotum, small head and color of the legs will ren- 

 der the identification of this small but distinct species alwaj'S 

 easy when the locality is known, as it is undoubtedly confined to 

 the island. The specimen described above has the fifth ventral 

 broadly truncate at apex and is apparently a male.
