the mandibles less closely and less roughly punctured. The 

 mandibles are also quite different in form from those of the 

 small male type of P. iphis, being elongated, strongly curved, 

 rather cylindrical, and unarmed towards the base, and dilated 

 and compressed to a thin cutting-edge at the extremity, as in 

 the larger males of P. cacicus, White, and P. Buckley i, 

 Waterh. This difference, however, is not greater than might 

 be expected to occur between forms of major and minor deve- 

 lopment within the limits of a single species, and must not be 

 looked upon as a character for distinguishing the species. 

 The two prominent and very distinct ridges on the upperside 

 of the head, running back from the antennal tubercles, the 

 absence of smooth callous areas from the base of the pronotum, 

 and the feebleness of the punctuation of the abdomen are 

 characters that readily distinguish the present species from 

 P. Bucklet/i, Waterh., and presumably also from the 

 P. Whymperi and P. trigonodes of Bates, who has not men- 

 tioned any of these characters as distinguishing his species 

 from P. Buckleyi.

J . Piceo-niger, nitidus ; prothorace supra medio vix punctato, 

 versus latera sat dense et subrugose punctato, disco bituberculato, 

 tuberculis sat remotis, obtusis et paullo elevatis ; elytris leviter 

 coriaceis, minute haud dense punctatis, nitidis, apicibus rotun-

 elytrorum longe superantibus, articulis 6°-10 m apice iutus breviter 

 angulato-productis.

Resembles in colour and in many points of structure the 

 South-African species, A. capensis, White, but has the joints 

 of the antennas from the sixth to the tentli only slightly 

 produced and less acutely angular at the inner apex ; the eyes 

 are rather more widely separated above, and behind each 

 there is a rugose and depressed area, which extends a little 

 further upwards than does the eye itself; the mid-dorsal 

 region of the head forms with the front a continuous nitid and 

 almost impunctate area with an impressed line along the 

 middle ; the underside of the head and the sides of the breast 

 have a shorter and thinner pubescence, and this pubescence 

 is greyish rather than tawny in colour. The mandibles in 

 the two males of the present species are short, toothed along 

 the inner edge, and in form quite like those occurring in the 

 females and smaller males of the species of this genus.
