strongly from the base to the middle of the disk and 
enclose a low median scale-covered costa, and on each side 
of these an indistinct longitudinal impression. Antenne 
with joint 1 of the funicle longer than 2, the remaining 
joints short and gradually widening outwardly. Prothorax 
much broader than long, the base and apex of equal width, 
the former arcuate, the latter truncate, the sides very 
strongly rounded, broadest much before the middle; the 
upper surface closely set with small low confluent tubercles, 
and with an indistinct central furrow. Hlytra oblong- 
ovate, parallel-sided from the subhumeral prominence to 
beyond the middle, very broadly rounded behind, the basal 
margin not raised; with very shallow sulci, each containing 
a single row of deep close punctures; the intervals. only 
slightly convex and bearing a single row of broadly truncate, 
seale-like, erect sete.

Described from two specimens- 
Genus ProscerHauaperes, Schh. 
To this genus are here referred all the A frican “‘ Stropho- 
somus’’ having subglobose elytra. Apart from their some- 
what different facies, they may be distinguished from the 
other African species with which they have hitherto been 
associated by the following points :—The mentum is entirely 
devoid of true sete, though in most of the species there 
is a row of scales along its anterior edge—a very unusual 
character; the corbels of the hind tibiz are more nearly 
terminal in position; the first joint of the funicle is never 
longer than the second, being rarely equal to it and usually 
distinctly shorter; the apical margin of the rostrum is 
deeply sinuate ; and the hind coxe are distinctly separated 
from the elytra. 
The true European Strophosomus differ in having non- 
squamose and non-carinate mandibles, non-squamose funicles, 
a distinctly longer metasternum, and more coarsely facetted 
eyes. 
The described species which ‘should be placed here are: 
Strophosomus aspericollis, Fhs., S. lineatus, Fhs., S. varia- 
bilis, hs. (Ofv. K. Vet.-Ak. Forh. 1871, pp. 13, 14), 
S. binotatus, Mshl., and 8. salisburiensis, Mshl. (Proc. Zool. 
Soe. 1906, pp. 912, 913) ; and more than a dozen additional 
undescribed species are known to me.
