This species together with P. aliena and " Sternotomis" bicolor are distiii- 

 gnished from the other sjjecies of Prosopocera hj the peculiar whitish green 

 tomeiitum of the upperside. la both aliena and bicolor the head and thorax have 

 the chxyish colour of the under surface, while in lameeri the occiput and prouotum are 

 coloured like the elytra. P. aliena differs, besides, in having the sutnral angle of 

 the elytra dentate and possessing very small prothoracical spines, which are barely 

 traceable in our d from Lolodorf, Cameroons ; whereas bicolor can be distinguished 

 from the other two species by the scape of the antenna just reaching the prothorax. 



5'J. Prosopocera insig'nis spec. nov. 



c? ? . Variegated with a brown, black, and greenish white tomentum ; a double 

 spot on occiput, a spot behind the side-spine of the prothorax, another, transverse, 

 on each side of the disc before middle, and a less distinct one in front of the 

 scnti'llum, the usual lateral posthumeral spot of the elytra and the discal ante- 

 median one, velvety black, more or less encircled with greenish white ; this latter 

 tomentum especially conspicuous on the prothorax in front of and below the 

 spine, on the elytra round the black spots and behind middle, on the sterna and 

 abdomen as spots and patches, and on the legs as rings ; the punctures of the 

 prothorax and elytra black. 



Frons unarmed in <?, with dispersed jJcmctures near eye, an anterior mesial 

 patch greenish white. Antenna three to four times the length of the body in 3 , 

 one-fourth longer than the body in ? : scape reaching just beyond the antemedian 

 sulcus of the pronotum, with disjjersed coarse punctures : third segment at least 

 half as long again as the scape, reaching in J to black posthumeral spot 

 of elytra. Disc of pronotum punctured in front and at the sides ; antemedian 

 transverse groove deep, bent backwards in middle ; mesial callosity in front of 

 basal constriction and lateral discal callosities distinct but not prominent ; 

 side-spine verj' prominent, broad at base. Elytra gradually narrowing behind, 

 dispersedly punctured all over, the punctures rather denser near the shoulders 

 on upperside, and their anterior edges here raised to granules. 



Length, 23—30 mm. ; elytra, 16—20 mm. ; breadth, 9—12 mm.

Anoplostetha (1850) Reiche. 



There does not seem to be anything constant in structure which separates 

 Anoplostttha lactator from Prosopocera. Two of the geographical forms of 

 lactator have indeed been described as Prosopocera. There are at least four 

 or five subspecies of this species, connected by intergradations, namely : — 



(a) P. lactator iiieridiowilis subsp. nov. 



S ? . White frontal patch generally large ; head white behind eye ; dorsal 

 patches of prothorax reaching to antemedian groove ; basal patch of elytrum 

 triangular ; granulation of base extended to near suture in both sexes ; breast 

 white, excejjtiug lietween and in front of coxae, the white tomentum covering the 

 mutasternum anteriorly ; abdomen in S with a single white mesial stri[)e or this 

 stripe divided, in ? entirely white or with small brown mesial and lateral marginal
