COLEOPTERA. 179 



tiguous elytra, sub-cylindrical after the first, which alone is distinctly mar- 

 gined ; surface very deeply, closely, evenly, and rather coarsely punctate; 

 punctures about as large as those of the elytra ; interspaces feebly convex, 

 narrower than the punctures, highly polished. Legs short and slender, 

 black, tarsi rather dark piceous-brown, joints very robust, densely hirsute, 

 especially beneath ; fust joint scarcely two-thirds as long as the last ; fourth 

 joints very strongly- hi lohed, third very deeply emarginate at tip. 



Male. — Sixth Segment broadly incised, incisure occupying the entire seg- 

 mental width at apex, sides nearly straight, anterior angle rather broadly 

 rounded, exterior angles rounded, width nearly four times the depth ; seventh 

 segment obtusely rounded behind. 



Female. — Sixth segment angularly and acutely produced at tip, sides of 

 angle very feebly sinuate. 



Length 3.8-4.4 mm.

This species approximates more closely to the European tarsalis 

 Ljungh than any other which I have been able to examine ; it, differs 

 from that species as follows : — 



The elytral punctuation in tarsalis is -more even in distribution 

 and in the size of the punctures, the elytra together are shorter and 

 more strongly emarginate behind, and the maxillary palpi are shorter 

 and more robust than in litem's. 



In the former the tarsi are less robust, less strongly pubescent, and 

 have the first joint relatively longer than in the latter. 



The sixth segment in thp female of tarsalis is more obtuse behind, 

 and more acutely and abruptly produced as a cusp-like point at the 

 immediate apex than in the like sex of utenis. 



There are other differences, especially in the more robust shape of 

 the American species, which might be given, but the above will serve 

 to show that the two species are almost unquestionably distinct. 



The tarsal claw as figured, plate, fig. 15, is seen to be more 

 abruptly bulbous at the base than that of tarsalis. The conform- 

 ation of this appendage docs not vary appreciably with sex, as far as 

 I have been able to observe. 



24. A. trajectus n. sp. — Form robust. Pubescence rather long, fine, 

 evenly distributed, sub-recumbent, dark cinereous, moderately conspicuous. 

 Head moderate in size ; labrum broad, rather prominent ; interocular surface 

 two and one-half times as wide as the eye, flat; sulcations narrow, conver- 

 gent, rather feeble ; intermediate surface twice as wide as the lateral portions, 

 very feebly and broadly convex ; punctures rather irregular in outline, dose, 

 almost evenly distributed ; ocular lines meeting at two lengths in advance ; 

 antennae rather longer than the width of head, somewhat slender, club 

 moderate, basal joint piceous-black, remainder pale testaceous, club just 

 visibly darker; third joint one-half longer than the fourth, joints of club
