strongly convergent to the truncate apex, the latter not visible from above but 

 narrow and feebly sinuate ; declivity coarsely asperate above, smoother near the 

 apex, subserrate laterally, the teeth not extending to the apex; basal half rather 

 dull in lustre and with short strigiform lines not densely placed. Elytra about 

 twice as long as wide, between two and three times as long as the prothorax and 

 rather wider, rather coarsely, deeply and irregularly but uniformly and quite 

 densely punctate, very densely and perforately so behind, the declivity moder- 

 ately steep, more convex at each side but not tuberculate, the suture elevated. 

 Abdomen closely punctulate, the pubescence moderately abundant. Tarsi very- 

 long. Length 6.5-7.0 mm. ; width 2.0-2.2 mm. Texas (El Paso). 



brevicollis, sp. nov. 



Small species, 4.5-5.5 mm. in length, the prothorax as broad as long. Body elongate, 



cylindrical, sparsely clothed with moderately long semi-erect hair; elytra 



coarsely and' seriately punctate; under surface sparsely punctate. California

Grandicollis is described from what appears to be the male, but 

 the eyes are very small when compared with those of brevicollis, of 

 which the four homogeneous examples before me seem to be females ; 

 both of these species and probably teres also, which I have not seen,- 

 have the funicle of the antennas much shorter than in the others; in 

 grandicollis the five joints together are however quite distinctly longer 

 than the first joint of the club ; in brevicollis they are barely as long as 

 the first joint but do not have the closely crowded structure observed in 

 Sinoxylon and Tetrapriocera. In brevicollis there are a few erect hairs 

 observable near the sides of the elytra especially behind, but otherwise 

 the surface is glabrous and the punctures are only feebly subseriate in 

 arrangement. 



Apatides, gen. nov. 



This genus is amply distinct from Amphicerus in the characters of 

 the table. We have the following three species: — 



Inner margin of the epipleurae continuous and obliquely ascending at base to the 

 humeral angles in the female ; basal angles of the prothorax acute and promi- 

 nent; head and abdomen finely punctate, the former slightly tumid or subcari- 

 nate along the middle toward the frontal margin. Lower California and 

 California (Yuma) fortis Lee. 



Inner margin of the epipleurse discontinuous at base in the female, basal angles of the 

 prothorax not at all rounded but at the same time not distinctly prominent, the 

 surface less impressed before the angles 2 



2 — Vertex gradually ascending to the prominent frontal margin, finely and sparsely 

 punctate, the abdomen minutely punctulate throughout ; thoracic processes 

 separated by rather more than a third of the total wr.dth. Male. — Head three- 

 fifihs as wide as the prothorax, the latter nearly as long as wide, with the
