HARPALIISLE 231 



inference merely, as I have not seen his types and the large series 

 sent to me by Dr. Keen and Mr. Sherman display all the color 

 variations which seem to serve largely as the basis for the published 

 names. Nitens Lee., is a species evidently distinct from ruficrus 

 (axillaris} and not synonymous as thought by the author.

Although so different in the elongate-oval, very convex body, 

 with hard dense glabrous integuments and obsolescent elytral striae, 

 there can be but little doubt that this genus is more closely allied 

 to Trichocelhis than it is to Bradycellus; this is indicated by the even 

 sparse punctulation of the abdomen and by the male abdominal 

 and tarsal modifications. The head is relatively much smaller 

 but with very prominent eyes, the antennae rather short, mentum 

 tooth slender and very acute, the ligula feebly dilated at apex, the 

 inner lobe of the maxilla strongly hooked and with very coarse 

 cilia, the last joint of the outer lobe moderate in length, gradually 

 thicker toward base and very finely subulate apically and the second 

 labio-palpal joint is barely at all shorter than the third. The 

 prothorax has well defined basal angles and, along the sides in the 

 finely reflexed edge, there is a series of erect setae arising from very 

 moderate punctures and recalling a rather similar structure in 

 Nothopus and Hartonymus. One section of smaller species has only 

 one marginal seta, the others having become obsolete, but a careful 

 inspection of the fine marginal gutter shows a feeble irregular 

 crenulatioh, this being a vestigial remnant of the normal series of 

 definite setigerous punctures. The elytra have all the elytral 

 striae, excepting the deeply impressed sutural and feeble eighth and 

 ninth, completely obsolete or sometimes represented by very 

 feebly impressed punctulation. The discal puncture and scutellar 

 stria are obsolete, although the annuliform fovea of the latter is 

 well developed. The anterior tarsi of the male are feebly dilated 

 and have beneath joints 2-4 slender, hyaline, acutely pointed and 

 decumbent squamules, extending transversely and closely out- 

 ward from the median line, the first joint with only one or two 

 squamules at apex and not transversely arranged; the middle 

 tarsi are slender and unmodified and the posterior slender, with the 

 first three joints decreasing uniformly and rapidly in length. There
