1. A. pleuralis Casey. — Elongate, parallel, moderately convex, piceous 

 brown, antennae and feet paler; pubescence very fine, short, moderately inclined, 

 not obscuring the surface color. Head distinctly narrower than the prothorax, 

 eyes moderate; antennae (fig. 28) scarcely half the length of the body; second 

 joint short, oval, third to tenth elongate-triangular, varying from one and one- 

 half to two and one-half times as long as wide; increasing slightly in length out- 

 wardly and evidently more slender in the male; surface rather dull, mod- 

 erately closely punctate. Prothorax transverse, sides feebly arcuate and a little 

 convergent toward the front; margin narrow and finely serrulate, front angles 

 distinct and nearly right, hind angles broadly rounded ; surface smooth, without 

 punctures but numerously granulate; median line impressed in front, obviously 

 but not strongly compresso-carinate behind. Elytra not wider than the protho- 

 rax and four times as long ; feebly punctate-striate, the punctures becoming obso- 

 lete near the apex. Beneath finely punctate and pubescent. Length 3-5.2 mm. 



California (Santa Cruz Mts., Pomona and Pasadena), occurring 

 in the spring on live oaks. 



The sexual differences appear to be confined to the slightly longer, 

 male antennoe. 



The above description was written before discovering that what 

 is undoubtedly the same species had been previously described 

 by Casey under Euceratocerus. I have substituted Casey's name 

 and will let the description stand. Since macer and saginatus are 

 unknown to me, I can only transcribe the original descriptions and 

 also add that of pleuralis for purposes of comparison. It is more 

 than likely that the three names cover only a single species. 



*' Euceratocerus pleuralis" Casey. — "Pleural sulcus below the 

 humeri deep and strongly marked ; elytra twice as long as wide; eyes separated 

 by evidently more than three times their own width. Body rather stout, the 

 elytra subdilated near the tip, blackish piceous above, the legs and antennae dark 

 rufous or rufopiceou? ; surface feebly shining, the pubescence extremely short, 

 pale, dense and conspicuous on the elytra. Head short, inserted to the eyes, dull, 

 the epistomal impression well marked. Prothorax three-fifths wider than long, 

 rounded at apex, the sides thence strongly diverging and feebly sinuate, becom- 

 ing parallel and broadly rounded in basal half; basal angles rounded. Elytra 

 twice as long as wide, more than three times as long as the prothorax and fully 

 as wide, a little wider at apical third ; humeral angles rounded. Length 3.7-4.5 

 mm. ; width 1.3-1.7 mm. 



"California — Santa Cruz Mts." 



2. V. macer Casey. — " Elytra fully twice as long as wide; eyes small, sepa- 

 rated by fully four times their own width. Body very slender, nearly as in 

 pleuralis but narrower, the elytra not distinctly wider behind and fully three and 

 one-half times as long as the prothorax, the latter nearly similar in outline but 

 still more transverse, the sides becoming parallel in less than basal half, with the 

 median line similarly finely impressed anteriorly. Length 2.9 mm. ; width 1.0 mm.
