274 MEMOIRS ON THE COLEOPTERA 



on the declivity; discal puncture behind two-thirds; hind tarsi long 

 and slender, proportionally rather shorter than in fuliginosus, 

 though nearly similar in structure, three-fourths as long as the tibiae; 

 male with the anterior tarsi distinctly dilated, the intermediate 

 slender. Length (cf 9 ) 7-4-7-9 mm.; width 2.75-2.8 mm. Cali- 

 fornia (San Diego). Four examples, very uniform in every way. 



flavipes Lee. 

 II Pronotum uniformly black throughout, only the very fine edges dia- 



phanously pallescent 12 



Pronotum more or less broadly and nubilously pale at apex and base and 



generally more narrowly at the sides; hind angles of the prothorax 



less rounded than in any other species of the genus. . . . . 17 



12 Head well developed, about three-fourths as wide as the prothorax, 



with notably prominent eyes - - 13 



Head relatively smaller, three-fifths to two-thirds as wide as the prothorax, 



with the eyes much less prominent .16 



13 Elytra deep black or with the suture alone paler .14 



Elytra obscure brown in color 15 



14 Form rather slender, moderately convex, shining, very deep black 

 throughout above and beneath, the suture not paler; outer edge of 

 the epipleura pale; legs varicolored, the femora black, pallescent 

 at base, the tibiae testaceous, black apically, the tarsi deep black; 

 head smooth, the eyes prominent; antennae slender, black, the basal 

 joint pale, with a blackish cloud; prothorax a third wider than long, 

 the sides parallel, evenly and broadly rounded; apex feebly sinuate, 

 with distinct angles and as wide as the base, which is feebly arcuate, 

 with broadly rounded angles; surface with a very fine, barely pal- 

 lescent reflexed margin, which is continued about the basal angles to 

 lateral fourth of the base, the foveae isolated, rounded, extremely 

 feeble and with a very few pun'ctures; median stria excessively fine 

 and feeble; elytra three-fifths longer than wide and not quite a 

 third wider than the prothorax, parallel, with broadly arcuate 'sides 

 and obtuse apex, the sinus very feeble; striae very fine, coarse and 

 deep at apex, the scutellar long but fine; intervals virtually flat, the 

 discal puncture behind two-thirds; hind tarsi slender, the first joint 

 not quite as long as the next two and somewhat longer than the 

 fifth; male with both the anterior and middle tarsi distinctly and 

 subequally dilated. Length (cf) 5-Q mm.; width 1.9 mm. Cali- 

 fornia (southern) remissus n. sp. 



Form stouter, shining, deep black above and beneath, the very fine 

 reflexed margins of the pronotum and elytra and the entire suture 

 of the latter finely rufescent; legs as in the preceding substituting 

 piceous for black, the femora rather pale, dark apically, the tarsi 

 nearly black; head very well developed, with prominent eyes; an- 

 tennae slender, blackish, the two basal joints pale; prothorax widest 

 somewhat before the middle, the sides more feebly arcuate than in 

 the preceding and only feebly so basally; apex still more feebly sin- 

 uate and with more obtuse and blunt angles, fully as wide as the 

 base, which is feebly arcuate, with broadly rounded angles; surface 

 very finely reflexed at the sides, a little more strongly so at the basal
