AMERICAN COLEOPTKRA. 407 



metasternum : underside coarsely punctured. Legs slender, tibise subparallel, 

 middle and ])osterior scarcely eniar<;inate above the apex, tai-si slender, third 

 broadly bilobed, fourth shorter than the two preceding joints combined, claws 

 with a short, median tooth. Leiigth 1.75-2.0 mm.; 0.08 inch. 



%. Last ventral segment with a small, rounded and deejtly impressed fovea. 



Hab. — i\rarvland ; Detroit, Mich. 



A male and female specimen are before me, one in the Nat. Mus. 

 coll., the other in my own. A very distinct species, easily reeojiiiized 

 by its robust form, small size, long and stout beak, prominent ocular 

 lobes, elytral ornamentation and short clawal tooth. I regret that 

 I have not been able to expose the antenna? for examination without 

 great risk of destroying the specimen ; for the same reason I have 

 been unable to examine the tibiie of the male. 



A. tacliygonoi<Ies n. sp. PI. xii, fig. 13.— Broadly oval, dark, piceous, 

 anteniue and legs rufo-jiiceous. above sparsely clothed with fine pubescence, in- 

 terspersed with large, white, erect scales on the elytra ; underside sparsely scaly. 

 Beak stout, shorter than the prothorax, a little widened toward the apex in the 

 male, very finely striate and punctured, scrobes expanded posteriorly, antennse 

 inserted at the middle ( % ), rather slender, funicle 7-jointed, joints 1-4 a little 

 elongated. 5-7 short, club oval, subacuminate. Eyes concealed in repose, poste- 

 rior margin elevated, free. Head convex, finely and not very closely punctured ; 

 prothorax as in subfasciatiis, punctures a trifle smaller: scutel very small. Elytra 

 less than one-third wider at the base than the prothorax, a little wider than long, 

 rounded on the sides to the apex, striie deep, closely punctured, interspaces con- 

 vex, very rugose, each with a row of very small, acute granules, each bearing a 

 short hair on its summit, a conspicuous white line on the sutural interspace ex- 

 tending about one-third its length ; pygidiuni neither coarsely nor densely punc- 

 tured, subciirinate in the female, sinijily convex in the male: pectoral groove 

 extending upon the metasternunj : underside not coarsely punctured, punctures 

 rather superficial, somewhat distant on the sternal side-pieces, arranged in rows 

 on the ventral segments. Legs, tarsi and claws as in the preceding species. 

 Length 1.75 2.0 mm. : 0.07-0.08 inch. 



% . Last ventral .segment not impressed, middle and posterior tibire not un- 

 guiculate at the apex. 



Hab. — District of Columbia (Ulke), Texas (Nat. Mus. coll.). 



One male and two females are before me, similar to but quite dis- 

 tinct from subfasciatns, from which it is distinguished by its much 

 shorter beak, different elytral ornamentation and the presence of 

 scattered, erect scales on the elytra. 



A. longirostris n. sp. PI. xii. fig. 1.5/>.— Robu.st, oval, entirely pitchy 

 black, above very sparingly clothed with a very short, fine pubescence, underside 

 very coai-sely punctured with few scattered .scales, legs more densely pubescent. 

 Beak slender, longer than the prothorax ( 9 )• curved, indistinctly subcarinate 

 about the middle third, striolato-punctate, scrobes subparallel, directed against 

 the eyes, antennse slender, inseited two-fifths from the base ( 9 )> funicle 7-jointed
