394 MEMOIRS ON THE COLEOPTERA 



moderately concave; prothorax longer than broad, coarsely but 

 sparsely punctate, with a broad, very faint and shallow impression 

 on the median line near the apex and a rather deep impression near 

 the middle of the lateral margin, so that the sides appear to be slightly 

 emarginate when viewed from above; disk of the elytra flat, with 

 moderately deep striae and convex intervals, irregularly disposed; 

 pygidium oblique, moderately convex, styliferous at apex, the process 

 short, flattened and rounded at tip; under surface rather shining and 

 coarsely punctured. Length 9 mm. California (Fort Crook). 



californicus Horn 



The large size and some other features of californicus, suggest 

 that it may come under some one of the numerous genera recently 

 erected at the expense of the old heterogeneous Valgus. I have 

 heard nothing concerning a rediscovery of this interesting species 

 and assume that it has never been found since the original type 

 was taken from a spider's web by the describer. Squamiger and 

 canaliculatus are abundant, but of mimttus I only have three 

 examples, so that I cannot say positively that the male is always 

 relatively so much more abundant than the female in the canalicu- 

 latus type as might be inferred from the numbers stated above; in 

 squamiger the males and females seem to be almost equally numerous 

 in individuals. 



In Valgus I can perceive no trace of suture between the propy- 

 gidium and fifth ventral segment, and the last spiracle is very small, 

 somewhat tumidulous and at apical third; the other spiracles, 

 covered by the elytra, are extremely small.
