%. Anterior feniin-a luerely swollen ; sniootli aveii not striate: limiting ridge 

 evident; tibial armature minute; other characters as usual. 

 9 . Elytra prolonged at tip. 



Hab. — Georgia, Florida. 



Three males and one female are before me, agreeing in all essen- 

 tial characters; I cannot, however, be absolutely sure that the female 

 is properly referred, the male is therefore to be regarded as the type. 



17. A. Kill 111 rostrum n. sp. — Elongate, black, with or without seueous 

 lustre; pubescence fine, sparse. Beak {%) as long, ( 9 ) noticeably longer tlian 

 the head and prothoras, stouter at the base, more .slender, nearly cylindrical, 

 polished and subimpnnctate beyond the insertion of the antennje. When viewed 

 in profile the base, beginning at the insertion of the antennae, is flattened or 

 even slightly concave above. Antennae about as usual ; the first joint scarcely as 

 long as the next two ( % ), or fully as long ( 9 )• Front moderately wide, longi- 

 tudinally rugulose ; eyes moderate. Prothorax cylindrical, rather more longi- 

 tudinally convex than usual; sides arcuately prominent at the middle; surface 

 rather sparsely punctate: impressed line more or less imperfect. Elytra rather 

 strongly longitudinally convex ; humeri nearly wanting; sides divergent to the 

 middle ; strife moderate; intervals flat or slightly convex. Beneath sparsely punc- 

 tate ; legs rather slender; claws nearly simple. Length 1.7 mm.; .OtJ inch. 

 (PI. II, tig. 21). 



%. Front thighs merely swollen: smooth area not noticeably striate; other 

 characters as usual. 



9. Tips of elytra scarcely produced. 



Ilab. — Florida (Lake Ashby). 



Several examples collected by Mr. Schwarz or Mr. Hubbard. 

 The form of the beak is unique and sufficient to distinguish this 

 species from any of the related forms. 



18. A. iiiolostiiin n. sp. — Moderately elongate, black, moderately shining, 

 without feneous lustre; pubescence nearly wanting. Beak ( 1, ) shorter than the 

 head and prothorax, dilated at one-third from the base, more slender and feebly 

 attenuate beyond the dilatation; punctuation sparse, fine; polished and nearly 

 impunctate in apical third ; ( 9 ) longer than the head and thorax, very slender, 

 not dilated, strongly, evenly arcuate, obsoletely punctulate ; the finer sculpture 

 extending to or a little beyond the middle. Antennse brown, first joint equal to 

 ( % ), or a little longer than ( 9 ) the next two. Front canaliculate ; eyes promi- 

 nent. Prothorax a little longer than wide ; apex nearly as wide as the base ; 

 sides slightly prominent at the middle; surface rather coarsely and closely punc- 

 tate; impressed line complete. Elytra moderately, longitudinally convex, widest 

 at or a little behind the middle; humeri wanting or but faintly indicated ; stria* 

 dee]); intervals more or less convex, especially toward the base. Abdomen 

 rather coarsely, not sparsely punctate. Length 1.6 ram. ; .06 inch. 



%. Front thighs merely swollen ; smooth area not striate; one or two stria? 

 adjacent to the limiting ridge, which is well marked; stitural angles rounded: 

 other characters as usual in the group. 



9. Sutural angles scarcely rounded, somewhat produced. 



Hab. — Illinois (Liebeck).
