sinuate-truncate, the sutural angle of the truncature being ad- 
vanced but obtuse, the external angle prolonged into a stout 
spine j the posterior carina, which in P. partitus is very long, is 
here reduced to a faint elevation close to the tip of each elytron, 
and the sutural stria is not strongly impressed ; the surface has 
many rows of setiferous punctures; the basal half is dingy 
ochraceous, much speckled with black ; the apical part has an 
ochraceous patch neatly limited on its anterior edge, and varied 
with dusky points, the extreme apex near the suture having a 
smaller opake ochreous spot ; the rest of the elytra is dull black- 
ish, which colour forms a broad fascia, varied only by minute 
grey linear specks, arranged in lines. Body beneath and legs 
dingy ashy ; tarsi pale testaceous ; apical segment of abdomen 
black ; ventral plate obtuse, dorsal plate truncate and bidentate 
in both sexes. 
This was rather a common insect at Ega, on branches of dead 
trees in the forest.

P. ellipticus, fusco-niger, fulvo-ochraceo variegatus : thorace dorso 
nigro, lineis duahus ochraceis antice convergentibus : elytris fusco- 
nigris, maculis ochraceis conspersis et fasciatis, apice oblique trun- 
catis, angulis externis vix dentatis : autennis nigris, infra parce 
setosis, articulo quarto basi pallido. Long. 4| lin. 
Head tawny ochraceous, vertex with two oblique flexuous 
dusky lines. Antennae black, two basal joints dingy ochraceous, 
fourth with the basal third of its length pale testaceous; they 
are setose, but the basal joint beneath is free from setae. Tho- 
rax on the sides tawny ochraceous, the middle blackish, with 
two oblique S-shaped streaks converging in front on the fore 
part of the disk ; the dorsal line is also dotted with ochraceous. 
Elytra strongly narrowed towards the tip, which is not spined, 
but obliquely truncated, with the sutural angle rounded off and 
the external one simply acute; the surface is furnished with 
rows of setiferous punctures ; there is no posterior carina, and 
the colour is shining brown-black, with a sprinkling of tawny 
specks, some of which collect to form two indistinct narrow 
fascise, one near the middle, the other near the apex. > Body be- 
neath dusky, with dingy ashy pile ; margins of ventral segments 
whitish. Legs blackish ; claw-joints of the tarsi testaceous. The 
apical dorsal plate has shortish and rather blunt teeth.
