forming a line, distinct keel from the tubercle to the margins ; 

 the elytra have on the space next the sutural stria only a few 

 large faint punctures, then three yjairs of rows of rather large, 

 lightly impressed punctures placed in feeble striae, both striae 

 and punctures failing a little behind the middle of the elytron, 

 then a nearly impunctate space extending to the margin, and 

 the apex is finely, faintly, and closely punctured. The pygidium, 

 underside and legs do not differ noticeably from those of 

 P. porcelliis (?). The apical ventral segment in the male (as 

 usual in this genus) has a sinuous line (which is ciliated with 

 golden hairs) running across it from margin to margin. 



The system of faint puncturation on the prothorax and the 

 absence of any trace of a protuberance on the clypeus of the 

 female will distinguish this species from P. 2^orcellus, Er. 



I possess a single pair taken by Professor Tate at Ouldea. 

 P. (? hujiis generis) duhius, sp. nov. Oblongus ; minus latus ; 

 nitidus ; obscure rufescens ; capite rugoso ; clypeo antice 

 subf ortiter bisinuato ; prothorace baud evidenter punctu- 

 lato ; elytris minus f ortiter punctulatis, vix striatis ; tibiis 

 anticis externe fortiter tridentatis. Long. 7i — 9 1. ; 

 lat. 3f, 4il. 



Mas. Sutura clypeali elevata in medio tuberculata. 



Eem. Capite baud tuberculato. 



In the few examples that I have seen of this insect the suture 

 is rather widely iufuscate, and in some specimens also the head 

 and apex of elytra (these latter parts I find liable to infusca- 

 tion in all the species of the genus j. The head scarcely differs 

 from that of P. crassus, except in having the clypeus very dis- 

 tinctly bisinuate in front. The prothorax scarcely differs in 

 shape or proportions from that of P. por callus {'^). Under a strong 

 Coddington lens it is seen to be sprinkled towards the sides 

 with very fine needle-point punctures. The scutellum is im- 

 punctate. The sculpture of the elytra is almost exactly as in 

 P. crassus. The rows of punctures on the elytra, however, do 

 not run noticeably in pairs. The pygidium and underside do 

 not differ noticeably from those of the other species I have de- 

 scribed. 



I hesitate much to refer this insect to Fimelopus, and think 

 it very likely that a new generic name may be required for it 

 eventually. It is a distinctly narrower insect than any of the 

 species described above, and has not the posteriorly swollen 

 appearance that they present. Its middle and hind tibiae also 

 are less stout, and are only unicarinate on the external margin. 

 In these respects it approaches Pseuclopimelopus, but its tarsi 

 and sexual characters are distinctly those of JPimelopus. As I 

 have not a specimen that I can devote to dissection, I place the 

 species for the present under Pimelopus.
