150 MEMOIRS ON THE COLEOPTERA 



There can be but little doubt that tetrlcus and consobrinus are 

 allied, but the fact that the side margins of the elytra are said to be 

 scarcely evident in consobrinus and the published figure (Rev. 

 Ten., plate), indicating a much more inflated hind body, with 

 more strongly arcuate sides, coupled with the absence of any allusion 

 to faint elytral costulation, would seem to show that they are 

 distinct, even allowing for the possibility that the figured type of 

 consobrinus may be a female. The general facies of these species 

 strongly suggests a still more abbreviated puncticollis, but the 

 sides of the less convex pronotum are much more broadly reflexed. 



Group V--Type angulatus Lee. 



The rather numerous species of this group are even more closely 

 confined to the limits of California than those of the costipennis 

 group and are more especially peculiar to the coast fauna, extending 

 northward as far as San Francisco Bay. They are distinguishable 

 at once from any of the preceding groups by having no vestige of 

 cariniform side margins of the elytra; although the elytra may be 

 sharply margined occasionally toward base, this margin is never 

 cariniform but due to a simple compression of the flanks and seems 

 to be more especially developed in the male. The group may be 

 divided into two sections, the second of which is more essentially 

 southern, being abundant in the vicinity of San Diego. 



Sides of the prothorax subparallel and evenly, rather strongly rounded 

 as in the preceding group 2 



Sides of the prothorax dilated and prominent at or behind the middle, 

 generally bluntly angulate; elytra sometimes having each two or 

 three very feeble fine vestigial costulse 9 



2 Head very finely and sparsely punctured. Black, shining, similar 

 in form to costipennis and differing in its very finely and sparsely 

 punctured head and more convex prothorax, which is less margined 

 and scarcely punctured; elytra elongate-oval, the margin broadly 

 rounded [in transverse section], the surface entirely smooth and 

 without trace of costae. Length 15.0-20.0 mm. California (east 

 and west sides of the Tulare Valley, several hundred miles northward 

 of Fort Tejon). [Asida captiosa Horn] captiosus Horn 



Head punctured as in costipennis and related forms, the punctures rather 

 large, deep and conspicuous -and usually mingled with very small 

 punctules scattered over the interspaces 3 



3 Smaller species from the middle coast regions 4 



Larger species from the more southern and interior regions of California. 5 



4 Body moderately slender, convex, deep black; head deeply impressed,
