H. C. FALL. 145 



Hub. — District of Columbia, Maryland. 



Described from two males and two females, collected by Mr. 

 Schwarz. A very distinct little species. 



54. A. iiebra!«keiise n. s]). — Moderately elon};ate, not very convex, wider 

 behind, moderately pubescent. Beak {% ) not quite as long as the head and pro- 

 thorax, distinctly narrowed toward to the tip; basal dilatation moderate; surface 

 rugose, very sparsely, obsoletely punctate in basal three- fourths: apical fourth 

 polished, impunctate. Antennae, front, eyes and prothorax as in the preceding 

 species. Elytra about one-half longer than wide; humeri moderate; sides 

 diverging to behind the middle; intervals wide, flat; striae not very strongly 

 impressed, especially toward the suture. Beneath rather strongly and coarsely 

 but not closely punctate. Length 1.8 mm. ; .07 inch. 



%. Sutural angles rounded ; middle and hind tibiae with a rather long slender 

 mucro projecting almost in a line with the length of the tibia. 

 9 . Not seen. 



Described from a single male taken at Superior, Nebraska, and 

 kindly given me by JNIr. Knaus. This species resembles both 

 novellinn and minor rather closely. From the former it differs most 

 noticeably by its more elongate form, more attenuate beak and flat 

 intervals, and from the latter by the slightly shorter first antennal 

 joint and much less coarsely punctured ventral surface. From 

 both it may be distinguished by the tibial mucro projecting in the 

 line of the tibia rather than at a considerable angle as is usual. 

 (PI. IV, fig. 20.) 



55. A. iniiior Smith.— Not very robust, black, moderately pubescent. Beak 

 ( %i ) rather slender, scarcely as long as the head and prothorax, dilated at one- 

 third from the base, attenuate, finely sculptured, except apical third which is 

 polished, a few vague irregular punctures at the sides, ( $> ) a little longer than 

 the head and thorax, very slender, less dilated and only slightly attenuate, 

 finely sculptured throughout; tip a little more shining; punctuation fine and 

 sparse. First antennal joint equal to the next two, secoTid nearly reaching the 

 eye. Front punctate, not sulcate; eyes moderately prominent. Prothorax 

 nearly as long as wide, width a little behind the middle equal to the base : sides 

 sinuate posteriorly; surface closely, coarsely, perforately punctate; basal fovea 

 not conspicuous. Elytra fully three-fourths longer than wide, sides parallel 

 ( ^ ) ; a little less elongate, sides feebly divergent posteriorly ( J 1 ; intervals 

 moderately wide and convex. Beneath very coarsely, deeply punctate. Length 

 1.5 mm. ; .06 inch. (PI. IV, fig. 10 and 10a). 



% . Middle and hind tibiae with long simple mucro. 

 9- Tibife unarmed. 



The sutural angles in the male are only slightly rounded and not 

 very different from the female. The small .size and very coarse, 

 deep punctuation of the prothorax and inferior surface, with the 

 long tibial mucro ( ^ ), readily separate this species from any 

 other known to me.
