Loiij,'. 13 miu., elytr. '.•, lat. 4. 



Head punctured, elothed with a deuse yellowish cinereous pubescence ; with a 

 fine glabrous median sulcus : cheeks short and not dilated. Mandibles smooth as 

 in Pr. iliabolictim Thorns, (whilst they are longitudinally striped or rugose in all 

 species of Acmocera Thorns, that I know). Antennae of the male scarcely twice 

 as long as the body, those of the female a third longer than the body : sca])e 

 glabrous, finely and transversely rugate-granulate, with a few hairs underneath ; 

 third and fourth joints fringed with rather sparse hairs, the fifth has also some long 

 hairs ; base of the third and all following joints white. Prothorax punctured all 

 over, with the punctures smaller than the interstices ; broader than long, broadest 

 in front, slightly constricted at the base, and nearly straight at the sides ; the 

 colour similar to that of the liead ; disc with a row of three irregular black maculae 

 at each side. Scutellum grey, as long as broad ; the apex subtruncate and feebly 

 emarginate. Elytra jinnctured like the prothorax, the punctures forming rows here 

 and there, and each giving origin to an erect black hair ; pubescence yellowish 

 ashy grey, variegated with black jiatches and spots, which almost form two irregular 

 transverse bands, one in front of, and one behind, the middle ; the base also black 

 beside the scutellum, and the ape.x has one larger black spot and a small one in 

 front of it ; besides these markings which seem to be constant, there are some more 

 small spots, chiefly in the middle. Pubescence of the under surface similar in colour 

 to that of the upperside. Metastcrnum punctured laterally : abdomen with long 

 grey hairs ; the extreme base of the abdominal segments, a small spot on the 

 posterior femora, and the tip of the tibiae black. 



Hab. Kuilu (A. Mocquerys, 189^). 



The relatively short antennae of the mulr, with the basal joints sparingly 

 fringed witli long hairs, give this species an appearance which is somewhat 

 difterent from that of Pr. diabolicmn Thoms.; but, in other respects, it agrees (|uite 

 well with this species, so that there is no doubt that both species belong to one 

 genus.
