80 CASEY 



evenly punctate and apically sinuate but having the sides before 

 the eyes much more prominent and very much more so than the 

 posterior canthus ; prothorax two-thirds wider than long, the sides 

 evenly converging and broadly, evenly arcuate from base to apex, 

 more strongly so than in insular is, the apex narrower, not more 

 than half as wide as the base, the punctures not quite so large and 

 a little closer, the hind angles not quite so acute ; scutellum some- 

 what smaller and less broadly triangular; elytra formed almost 

 exactly as in insularis but less shining, more uneven and with 

 the punctures not quite so small though distinctly smaller than 

 those of the prothorax and much denser than in insularis, simi- 

 larly finer and feeble laterally ; prosternal process moderate, 

 rounded at tip, spatulate, finely and sparsely punctate ; basal joint 

 of the hind tarsi longer than in insularis, being distinctly longer 

 than the remaining joints combined. Length 9.5-9.8 mm. ; 

 width 4.3-4.8 mm. Island of San Clemente...clementinus n. sp. 



It is my impression that the type oijinitimus was taken on the 

 island of Sta. Rosa, though this is little better than a surmise ; 

 it differs notably from insularis in form and punctuation. In- 

 sularis is not properly a variety of latus as originally described. 



Coniontis Esch. 



This genus, by far the most extensive of the Coniontinae, is 

 essentially peculiar to the Pacific coast of temperate North 

 America, extending to the eastward in the more northern lati- 

 tudes and thence southward along the Rocky Mountains to 

 southern Colorado. It has not yet been reported from north- 

 western Mexico and I have seen not a single example from New 

 Mexico and but one from Arizona, probably collected in the 

 extreme western part ; it appears to occur also on some of the 

 islands off the southern California coast, although probably as 

 a comparatively recent migrant. The body is oblong to oblong- 

 oval in form, convex, stout to elongate, strongly punctured to 

 almost smooth and glabrous to rather conspicuously setose. 

 The basal margin of the prothorax is never more than feebly 

 bisinuate, and the basal angles are always very much less prom- 

 inent posteriorly than in the preceding genus or the Eusatti. 

 The male is generally much smaller, less dilated and occasion- 

 ally somewhat more posteriorly attenuated than the female, but 

 does not differ much otherwise. 



There is probably no group of Coleoptera that to the system-
