by the greater extension of the head behind the ej^es and parallel 

 eh^tra, which are abruptly and broadly rounded at apex and not 

 gradually narrowed behind the middle. From cursor, in addi- 

 tion, it may be known by its smaller size, much narrower form,^ 

 narrower and less transverse anterior lobe of the prothorax and 

 much sparser punctuation throughout, and, from alacer, by its 

 narrower prothorax, with the punctures denser along the middle 

 anteriorl}', narrow and strong post-scutellar impression and 

 several other characters. The sexual characters of the single 

 male before me are nearly similar to those of alacer. 



7. I,, lividus n. sp. — Narrow, the elytra rather depressed, polished, pale 

 rufo-testaceous, the abdomen except at hase, the elytra behind the middle and 

 the last five joints of the antennje blackish; elytra frequently entirely pale. 

 Head rather large, convex, minutely and very sparsely punctate, slightly 

 wider than long, broadly arcuate at base; eyes large, prominent, the tempora 

 very short, (]uite perceptibly angulate; antennae scarcely one-half as long as 

 the body, rapidly and strongly incrassate, the tenth joint scarcely as long as 

 wide, obconical. Prothorax large, only slightly narrower than the head, 

 slightly elongate, the anterior lobe transversely oval, the posterior about one- 

 third of the total length, distinctly expanded to the basal margin; collar small 

 and short; disk very convex, minutely and sparsely punctate throughout, the 

 vestiture inconspicuous. Elytra about three-fourths longer than wide, scarcely 

 more than two-thirds wider than the prothorax, quite distinctly dilated be- 

 hind the middle, thence gradually narrowed to the apex, which is not very 

 broadly subtruncate; humeri widely exjjosed but obliciuely rounded at base; 

 surface transversely and strongly impressed near the base, the post-scutellar 

 impression distinct; omoplates mod eratel}' prominent; punctures tine, sparse, 

 scarcely more distinct toward base, where the vestiture becomes more con- 

 spicuous biit still rather sparse, the hairs tending to stream transverselj" out- 

 ward in the transverse impression. Abdomen shining, the legs rather long and 

 slender. Length 2.7-2.9 mm. ; width 0.7-0.8 mm. 



Texas (San Antonio). 



The male has the fifth segment unmodified, feebly truncate at 

 apex, the genital segment broadly- and deepl}' sinuato-truncate 

 throughout its width, the lateral angles rather prominent. This 

 well marked species is represented by three specimens.

This ver}^ distinct species is amply described by LaFertc under 

 the preoccupied name elegans. My two specimens were taken at 

 Asheville, North Carolina. Length 2.7 mm.; width 0.75 ram.
