scarcely more than twice as long-; sides parallel and straight in 

 basal half, then narrowly parabolic ; striae fine, deep, strongly punc- 

 tured laterally. Length 1.8-2.8 mm.; width 0.75-1.2 mm. 



California (Los Angeles and San Diego). A very distinct spe- 

 cies, easily identifiable by its large elongate prothorax. The vesti- 

 ture is very easily abraded, and, out of a large series which I took 

 at San Diego, there is scarcely a specimen having more than a few 

 scattered scales on the upper surface. One specimen in my cabinet 

 is labeled "Arizona."

Oblong-oval, convex, black, the legs dull rufous; integuments 

 densely clothed with moderately large, broadly oval scales, uniform 

 in coloration, ochreous to cinereous on the upper surface, whiter 

 beneath ; recurved setse small and distant. Beak in the male short, 

 thick, nearly straight, feebly tapering from base to apex, coarsely, 

 densely squamose except near the apex, coarsely punctate, scarcely 

 longer than the head and prothorax, with the antennae inserted a 

 little beyond the middle, in the female long, very slender, equally, 

 evenly cylindrical and feebly arcuate throughout, smooth, finely, 

 sparsely punctate, squamose only very near the base, one-half longer 

 than the head and prothorax and scarcely visibly shorter than the 

 elytra, with the antennae inserted somewhat behind basal two-fifths ; 

 antennae slender, the second funicular joint slightly shorter than 

 the next two. Prothorax distinctly narrowed from base to apex, 

 broadly, rather strongly rounded at the sides, deeply constricted 

 behind the apex, the latter three-fourths as wide as the base ; disk 

 convex, slightly wider than long. Elytra at base one-fourth to 

 one-third wider than the prothorax, two and one-half times as long. 

 Length 2.1-2.4 mm.; width 0.8-1.05 mm. 



Texas. A rather small species, allied completely in the structure 

 of the beak, both in the male and female, to constrictus (Desmoris). 

 The original description is greatly in error in stating that the tarsal 

 claws are not connate ; they are rather long and completely connate 

 in basal fourth. The head behind the transverse groove is abruptly 

 and completely glabrous, highly polished, sometimes with merely a 

 very feeble transversely wavy strigilation, while in griseus it is dull 

 and strongly, coarsely reticulate.
