tarsi notably shorter thau in Pseicdopimelopus (another dis- 

 tinction noted by Burmeister between Erichsen's P. Porcellus 

 and bis P. nothus). In P seudopimelo'pus Lindi, moreover, the 

 hind and intermediate tibiae have only one well defined 

 transverse keel, and the basal joint of the hind tarsi is shorter 

 across the apex than down its central line, while in the species 

 I regard as true Pimelopits there are two strong transverse 

 keels on the middle and hind tibia? and the basal joint of the 

 hind tarsi is decidedly wider across its apex than its length 

 down the middle line. I have dissected several specimens 

 without discovering any di:fference likely to be generic in the- 

 mouth organs. 



P. Lindi, sp. nov. Nitidus ; f usco-castaneus ; capite ruguloso,.

The colour varies to some extent, the head and prothorax in 

 many examples being darker, and the underside and femora 

 paler than the other parts. The sculpture of the head and 

 clypeus consists of coarse puncturation or wrinkles which in 

 some specimens (mostly males) seems to be partly obliterated. 

 The clypeus is strongly transverse and moderately wide in 

 front, where it is strongly bisinuate in an upward direction ; 

 in the male the clypeal suture forms the well defined lateral 

 edges of a stout recurved horn, of which the front face rises 

 almost from the front margin of the clypeus and the hind face 

 from the level of the front of the eyes. The distance from the 

 front of the clypeus to the apex of the horn is about equal to, 

 and the height of the hind face of the horn above the head is- 

 about half as great as, the greatest width of the clypeus. In 

 the female the clypeal suture is not strongly marked, and 

 being least evidently defined in the middle gives the head a 

 slight appearance of being bi-tuberculate. The prothorax in 

 the male is just about, in the female a little less than, half 

 again as wide as long ; the front margin is rather more than 

 half as wide as the base ; the sides are strongly (male) or 

 moderately (female) rounded ; in both sexes the surface is 

 very shining and hardly distinctly punctured ; in the male 

 there is a large flat-bottomed excavation occupying the middle 

 two-thirds of somewhat less than the anterior two-thirds of 

 the segment. The floor of this excavation is finely and reticu-
