straight for two-thirds the length from the base, thence together rather acutely 

 rounded behind ; disk transversely, strongly convex, rather coarsely, densely 

 and asperately punctate ; interspaces dull ; pubescence fine, rather long and 

 dense. Length 7.5-9.0 mm. ; width 3.8-4.7 mm. 



Guadalupe Island. 



The present species, which is represented by a series of eight 

 specimens, is immediately distinguishable from the others b}^ its 

 narrow subcylindrical form, parallel and much more rectilineal 

 sides, and generally coarser pronotal punctuation. 



G. muricata Horn. — Represented by a good series showing slight 

 variation, especially noticeable in the size and density of the pro- 

 notal punctuation. The color varies from dark brownish-ferrugi- 

 nous to piceous-black. One specimen differs in its more broadly 

 oval form. 



Length 8. 0-10. .5 mm.; width 4.3-5.5 mm. 



C. punctulata Horn. — This species is represented by a homogene- 

 ous series of twelve specimens. The color varies from rather pale 

 rufo-ferruginous to piceous-black. 



Length 9.5-12.0 mm.; width 4 8-6.0 mm. 



All the species of this genus have a narrow, more or less incom- 

 plete, median pronotal line which is impunctate. 



CffiLlIS Esch. 



The genus Coelus is peculiar to the coast regions of California, 

 and is found in abundance in the sand dunes which line the sea- 

 shore. The species are somewhat closely allied, but scarcely to so 

 great a degree as in Coelotaxis and Coniontis. They may be recog- 

 nized by the characters given in the following table : — 



Anterior angles of epistoma distinctly prominent; size large grossilS 



Anterior angles not at all produced, broadly rounded. 



Form narrowly oval ; pronotal punctuation very fine and sparse, unevenly 



distributed ciliatllS 



Form broadly oval ; pronotal punctuation coarse and deep. 



Punctures sparse areiiai'ilis 



Punctures dense, evenly distributed, sometimes semicoalescent. 



globosiis 



These species vary considerably in size, but the general outline 

 and punctuation are quite constant, so that there can be no difficulty 

 in identifying the forms here described. 



C. grossilS n. sp. — Form rather broadly oval, very convex ; dark castaneous 

 to piceous-black, shining, minutely and sparsely setose above, more densely
