head and prothorax, nearly glabrous; sides parallel; surface levss shining. In 

 both sexes the punctures are rather large and confluent in longitudinal lines ; the 

 intervals more or less carinate. First antennal joint reaching the eye, as long as 

 the three following ( 9 ), a little shorter ( % ). Front flat, narrower than the tip 

 of the beak ; eyes feebly convex, not at all prominent. Prothorax nearly as long 

 as wide; base about one-fourth wider than the apex ; apical constriction feeble; 

 sides subparallel in basal half, with a slight posterior sinuatiou ; surface moder- 

 ately, strongly and closely punctate; an impressed line at the base. Elytra a 

 little wider at the middle; humeri moderate; sides feebly arcuate in basal half, 

 more strongly posteriorly; intervals rather wide, convex. Punctuation beneath 

 moderate. Length 1.5-1.7 mm. ; .06-.07 inch. 



%. Sutural tips rounded ; middle and hind tibiae mucronate. 



J. Sutural tips not rounded; tibite unarmed. 



Hab. — Arizona (Santa Rita Mountains, Wickliam). 

 A very distinct species and easily recognized by the canaliculate 

 and carinate beak, the narrow front and feebly convex eyes. 



62. A. peiiiiiMiilare n. sp. — Black, sparsely pubescent. Beak {%) not as 

 long as the head and piothorax, stout, strongly dilated a little behind the middle, 

 moderately shining, rugosely punctate at the sides, more finely and sparsely 

 above. Antennte rather short, first joint scarcely as long as the two following, 

 second subglobose, barely reaching the eye. Front feebly sulcate ; eyes not 

 prominent. Prothorax about as long as wide; base one-fourth wider than the 

 apex ; sides divergent to the middle, thence subparallel. Elytra one-third longer 

 than wide; humeri moderately prominent; sides subparallel, very feebly arcuate; 

 intervals wide, moderately convex, rather sti'ongly uniformly punctate bei.eath. 

 Legs not stout; claws strongly toothed. Length 2 mm.; .08 inch. (PI. V, figs. 

 2 and 2a). 



% . Sutural tips narrowly rounded; middle and hind tibi;e with a short mucro. 



9 . Not seen. 



Hab. — Lower California (La Chuparosa). 



A single male from the above locality. The sexual characters 

 and stout, strongly dilated beak at once separate this species from 

 any known to me. It resembles somevvliat reclu^am, which, how- 

 ever, by its simple claws belongs to an entirely different section of 

 the genus. 



6.3. A. cribricolle Lee — Robust, black, more or less feneous; pubescence 

 almost entirely wanting. Beak very short, stout, tapering from eyes to tip, and 

 punctate throughout in both sexes. Front striate; eyes small, not prominent. 

 Antennae with the first joint very little longer than the second, third reaching 

 the eye. Prothorax small, a little wider than long: sides divergent to nearly 

 the middle; parallel in basal half or three-fifths; surface rather finely, densely 

 punctate; an impressed line near the base. Elytra ventricose; humeri promi- 

 nent; sides feebly divergent or subparallel to behind the middle; intervals 

 usually not much wider than the striae, flat or feebly convex, usually shining, 

 but sometimes finely rugulose or transversely wrinkled and opaque. Beneath 

 strongly, moderately, closely, but not coarsely punctate; legs rather slender;
