truncate throughout the width, with the lateral angles slightly, 

 acute and prominent. 



4. L,, cursor n. sp. — Moderately shining, dark rufo-testaceous, the abdo- 

 men, posterior three-fourths of the elytra and antennte except toward hase,black ; 

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

 ately convex, 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. Prothorax distinctly narrower than the head and longer 

 than wide, the apical lobe broad, transversely 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 narrow 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 widelj' exposed ; 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 

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

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

 pubescent. Legs long and slender. Length 2.9 mm. ; Avidth 0.85 mm. 



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



I took the single male type at El Paso some years ago, and the 

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

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

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

 attached, as the differences presented are purely 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}' sinnato-truncate throughout the 

 width. 



The last joint of the maxillary palpi is ver}- large and wide, 

 with the outer side but little longer than the inner. 



5. I,, alacer n. sp. — Narrow, ])olished, pale rufo testaceous, the abdomen, 

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

 Head rather wider than long, moderately convex, minutely, sparsely punctate, 

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

 tempora short and convergent, merging 1)y a feebly marked angle into the 

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