three times as wide as long, with two very short basal strise which are strongly 

 divergent and distant at base by one-sixtli of tlie discal width. Legs rather 

 long and slender. Length 1,3 mm. ; width 0.75 mm. 



Pennsylvania. 



A single pair, dififering only in the length of the abdominal 

 carinse. The carinas appear to be variable in length as a general 

 rule in this genus, but are less variable in direction and are quite 

 constant in mutual distance asunder. The male t3'pe above de- 

 scribed has the last ventral very large, very broadly and somewhat 

 deeply impressed, the impression even ; last dorsal very broadly 

 but distinctly sinuate at apex. 



This species belongs near rubiciinda and gracilicornis, but dif- 

 fers greatly in its short subrecumbent pubescence and strongly 

 marked male sexual characters of the last ventral, also in the very 

 different form of the terminal notch of the last dorsal. It is also 

 closely allied to facilis, having the same minute decumbent pubes- 

 cence, but more distant abdominal carinas; it is intermediate be- 

 tween 7-uhicunda eivA facilis in many respects. 



R. iuepta n. sp. — Rather stout, convex, polished, subimpunctate, dark 

 red-brown, the elytra brighter rufous ; pubescence moderately abundant, 

 rather short, stifl', inclined. Head much smaller than the prothorax, with 

 three spongiose foveje, the two posterior smaller than the subapical ; eyes 

 moderate in size, well before the base ; antennae scarcely longer than the 

 head an'd prothorax, rather slender, the club stout, fifth joint nearly one-half 

 longer tlian wide, the eighth slightly transverse. Prothorax two-fifths wider 

 than long, rounded on the sides and widest just before the middle; lateral 

 foveas distinct, intermediate subobsolete, consisting of an oval impression so 

 feeble as to be discernible only in certain lights, near the posterior margin of 

 which there is an excessively minute puncture, only distinct under rather 

 high power. Elytra transverse, one-half wider than long, one-half longer 

 than the prothorax and nearly twice as wide ; sides strongly divergent ; discal 

 stria extending nearly to apical sixth. Abdomen, from above, but slightly 

 sliorter than the elytra and equally wide, the first segment nearly three times 

 as wide as long, with two straight divergent carinaj in basal third, separated 

 by about one-fourth of the discal width. Length 1.0 mm. ; width 0.65 mm. 



New Jersey. 



The single specimen before me is a female. The species belongs 

 near rubicunda, differing obviously however in its very minute 

 size, shorter, coarser vestiture and nearly obsolete subbasal fovea 

 of the pronotum. It is also allied to farlixm but has the pubes- 

 cence longer and coarser, and the abdominal carinas more distant ; 

 the size, also, is much smaller.
