truncate throughout the width, with the lateral angles slightly 

 acute and prominent. 



4. L.. cursor n. sp. — Moderately shining, dark rufo-testaceons, the alxlo- 

 nien, posterior tliree-fonrths of the elytra and antenna? except toward liase, black; 

 basal fourth of the elytra more llavate. Head a little wider than long, moder- 

 ately cpnvex, finely but strongly, rather closely and asperately punctate, 

 feebly pubescent, broadly arcuate and unimpressed at base; eyes large and 

 prominent, the tempora short; temporal angles rather distinct; antenna; 

 slender, feebly incrassate, one-half as long as the body, the tenth joint much 

 longer than wide. Profhorax distinctly narrower than the head and longer 

 than wide, the apical lobe broad, trans\ersely oval, very abruptly limited by 

 the constriction, the posterior occupying two-fifths of the total length, feebly 

 and gradually expanded to the basal margin; collar rather naiTOw but distinct; 

 surface strongly convex, finely evenly and closely punctate. Elytra nearly 

 twice as long as wide, scarcely more than twice as wide as the prothorax, just 

 visibly wider behind the middle than at base, thence feebly, gradually nar- 

 rowed and not broadly rounded at apex; humeri widely exjiosed; post scutel- 

 lar impression broad and feeble, the omoplates scarcely prominent; transverse 

 impression at basal fifth broad and very pronounced; disk closely punctate, 

 the punctures rather coarse toward base, minute but not more distant toward 

 apex; pubescence fine short and close, rather dark in color and inconspicuous 

 Init becoming pale, coarser, denser and more conspicuous in the pale area at 

 basal fourth. Ahdo)nen polished, minutely, remotely punctate and sparsely 

 pubescent. Zf(/.s long and slender. Length 2.9 mm. ; width 0.85 mm. 



Texas (El Paso); Arizona (Seligman and Peach Springs). 



I took the single male tj'pe at El Paso some j^ears ago, and the 

 Arizona specimens, collected b}' Mr. Wickham, do not seem to 

 differ, the male from Peach Springs being simply' a little more 

 sparsely punctate ; two specimens, marked " Kansas," are also 

 attached, as the differences presented are purel}- varietal. The 

 male has the fifth ventral broadly rounded behind, becoming 

 feebly subtruncate in the middle and unmodified on the disk, the 

 genital segment broadly, feebl}' sinuato-truncate throughout tiie 

 width. 



The last joint of the maxillary palpi is very large and wide, 

 with the outer side but little longer than the inner. 



5. Li. alacei* n. sp. — Narrow, polished, pale rufo testaceous, the abdomen, 

 elytra in posterior two-thirds and antenna; except toward base, blackish. 

 Head rather wider than long, moderately convex, minutely, spar.sely punctate, 

 broadly arcuate at base and unimpressed; eyes very large and prominent, the 

 tempora short and convergent, merging by a feebly marked angle into the 

 base; antenna- long and very slender, rather more than one-half as long as the
