more tumid, and the first joint of the anterior tarsi is noticeably 

 more elongate. The sexes are scarcely distinguishable. 



91. A. elutipes n. sp. — Eobust, black; tibiae and tarsi indistiuctly paler; 

 auteniiiE bi-owuish at base; pubesceuce moderate, condensed at the base of the 

 third elytral interval. Beak distinctly longer than the head and prothorax, 

 cylindrical, evenly arcuate, feebly dilated near the base, rather strongly i)unctate 

 throughout; supra antennal groove distinct. Antennae not stout, first Joint 

 nearly or quite as long as the next two, and nearly reaching the eye, eighth as 

 wide as long. Front punctate, without median sulcus; eyes moderate. Prothorax 

 a little wider than long; sides rather strongly arcuate ; basal margin expanded; 

 apical constriction well marked, moderately closely punctate; basal fovea shallow, 

 linear, nearly reaching the middle. Elytra about one-half longer than wide; 

 sides feebly arcuate and subparallel in basal two-thirds ; intervals flat, about one- 

 half wider than the striae. Abdominal punctuation moderately strong, not close, 

 confined almost entirely to the first two segments; legs long, slender. Length 

 2.1 2.3 mm.; .08.09 inch. 



Hab. — Lower California (La Chuparosa). 



Described from two examples, one of which, from tlie somewhat 

 sliorter beak and first antennal joint, I judge to be a male. Elutipes 

 has no very near allies, hut the tumid under body, thin legs and 

 lack of secondary sexual characters evidently associate it with 

 decoloratiun, einaclipes and carinatum. 



92. A. cai'iiiatiiiii Smith. — Rather stout, black throughout, or with the 

 antennffi, tihite and tarsi more or less brownish piceous; pubescence fine, very 

 sparse and inconspicuous. Beak stout, a little shorter than the head and pro- 

 thorax, feebly dilated at basal third, thence narrowing a little toward the tip; 

 surface variably punctate, usually quite coarsely, often subseriately at the sides ; 

 supra antennal groove distinct. Antennpe short, first joint scarcely as long as the 

 two following, .joints 6-8 transverse, the eighth strongly so, fourth reaching the 

 eye. Front rather narrow, deeply bisulcate ; eyes not prominent. Prothorax 

 broader than long; sides subparallel and nearly straight in basal half, thence 

 rather strongly narrowed and constricted before the ape.x ; surface densely, rather 

 coarsely punctate; iiasal fovea moderate. Elytra about one-third longer than 

 wide; humeri prominent; sides arcuately divergent to the middle or a little 

 beyond; striae coarse ; intervals narrow, strongly convex. Punctuation beneath 

 variable, usually moderately coarse and close; legs thin. Length 1..5-1.8 mm.; 

 .06-.07 inch. 



Hab. — Massachusetts, New York, Pennsylvania, Florida, 

 Louisiana. 



As in the three preceding species, secondary sexual characters are 

 practically wanting. In the width of the eighth antennal joint and 

 convexity of the elytral intervals this species, I think, surpasses all 

 others in our fauna. The types of concoloratum, both in the National 

 Museum and in the LeConte cabinet, are identical with the types of
