22 D-. G. A. K. Marshall on Afric in 
of equal length. Prothorax transverse, the basal margin 
finely carinate. Scutelium concealed. Elytra subglobose, 
fitting closely to the prothorax, with a subhumeral pro- 
minence and irregular punctation. Sternum with the gular 
margin shallowly sinuate, the coxe in the middle of the 
prosternum, the centro-sternite small and tubercular ; mes- 
episterna narrowly separated from the elytra and with a 
transverse furrow at their extreme base (often hidden by the 
prosternum); metasternum between the cox distinetly 
shorter than the mid-coxe and with a strong antecoxal fold, 
the episternum angularly produced inwards at the base, the 
episternal suture more or less obliterated at its apex ; the 
hind coxz narrowly separated from the elytra. Venter with 
the intercoxal process strongly angulated, and nearly as 
broad as the hind cox; segment 1 with a sma!l sinuation in 
the middle of the hind margin, segm-nts 2-4 subequal ia 
length. Legs comparatively slender, the femora only slightly 
clavate; all the tibiae with a row of five to seven stout spines 
along the inner edge of the apical half, the hind tibie with 
the corbels obliquely terminal, bare and distinctly enclosed ; 
claws connate. 
¢. The last ventral segment bears a large deep impression. 
Genotype, Pseudoblosyrus sharpt, sp. n. 
Superficially just like a Blosyrus, but distinguished by the 
setose mentum, the enclosed corbels of the lind tibiae, the 
angulated base of the metepisternum, and the irregularly 
foveate and tuberculate elytra. 
Pseudoblosyrus sharpi, sp. n. (PI. 1. fig. 2). 
g ?. Black, not very shiny, with sparse grey scaling on 
the elytra and pale bluish scales on the head and pronotum. 
Head with fine shallow punctation, the lateral sulci almost 
as deep as the central one; eyes hardly p-oduced backwards, 
their greatest depth well behind the m ddle, the hind edge 
of the orbit not projecting. Rostrum longer than the head, 
about as long as broad, almost parallel-sided, somewhat 
flattened above, with a strong complete central costa, which 
bifureates near the apex ; adjoining the costa on each side 
a broad, deep, oblique impression, the }unctation coarse, but 
very shallow. Antenne with joints 4-6 of the funicle sub- 
equal, bead-like, a little longer than broad, and shorter than 
3 and 7, which are nearly equal. Prothorax with the sides 
rather strongly rounded, broadest before the middle, the 
apical margin truncate, narrower than the base and quite
