116 AMERICAN COLEOPTERA. 



kindly tiUows ine to retain the type. It seems so very different 

 from anything else that I have ventured a description in the 

 absence of the male. 



S. A. atripes Smith. — Very robust for tliis section: entirely black witlioiit 

 teneous lustre: pubescence almost wanting. Beak ( 9 * ^i little shorter tlian the 

 head and prothorax, slender, (tylindrical. rather strongly arcuate, finely strigose, 

 except toward the apex; punctuation fine, sparse. First antennal joint as long as 

 the next two, third distinctly longer than the fourth, second reaching the eye. 

 Front canaliculate; eyes very prominent. Prothorax wider than long; sides 

 arcuate, moderately, closely punctate; median line nearly comi)lete. Elyti'a less 

 than half longer than wide ; humeri moderate, post-humeral siuuation not evident; 

 sides slightly divergent to the middle: striae moderate; intervals nearly flat, 

 twice as wide as the striae. Beneatli rather finely not closely punctate. Legs 

 not very sleuder: claws nearly simple. Length 1.8 mm.; .07 inch. iPl. II, fig. 18). 



Hab. — District of Columbia, Virginia, Georgia. 



Single females from each of the above localities in the collections 

 of Mr. Sehwarz, Dr. Horn and myself are all that I have seen of 

 this apparently rare species. Smith cites also California, but, I have 

 no doubt, erroneously. In the ab-sence of the male this species is 

 doubtfully assigned to the grouj) with prominently tuberculate 

 femora. The large thorax, short elytra, short slender beak ( 9 ) and 

 very prominent eyes will make it always easily recognizable. 



Since the above was written I have seen in the LeConte collection 

 a fourth example, also a female, from Florida. In this last the feet 

 are brownish. 



9. A. finiliiiitiin n.sp. — Elongate, blackilegs sometimes ])iceous brown; elytra 

 with faint violaceous lustre; pubescence almost wanting. Beak ( % ) barely as 

 long as the head and prothorax. moderately curved, strongly almost angularly 

 dilated, a little more slender be.vond the dilation ; surface finely, rather sparsely 

 punctulate, polished in about apical half; ( 9 ) uuich longer, very slender, cylin- 

 drical, not at all dilated, almost entirely polished. First joint of antennae about 

 equal to the next two [%). or three (9 ). third joint reaching the eye. Front 

 canaliculose; eyes moderate. Prothorax as wide at the middle as long; base a 

 little wider than the apex; sides rather more than usually prominent at the mid- 

 dle; punctuation rather fine and close; dor-sal line nearly complete; humeri 

 evident; elytra not strongly widened at the middle; striae moderate ; intervals 

 rather wide, flat. Beneath finely, rather sparsely punctate; claws merel.y 

 thickened at the base. Length 1.8-2 mm.; .07-.08 inch. (Pi. II, figs. 6 and 15)- 

 % . Sutural angles rounded ; second joint of antennae triangular when viewed 

 laterally, setiferous; femoral tubercle prominent, rounded; smooth area with 

 rather close, slightly irregular striae; limiting ridge strong; anterior tibiae very 

 strongly dilated ; other parts as usual. 

 9. Sutural tips slightly produced. 



Hab. — Massachusetts (Cambridge), District of Columbia, Michi- 

 gan (Port Huron).
