190 Mr. G. Lewis on 
The late Mr. Julius Flohr, I believe, left his collections to 
the National Museum in Berlin, and therefore I presume 
there is an example of this species there. But on some occasions 
Mr. Flohr kindly gave me his unique specimens. 
Hister rubricatus, sp. n. 
Late ovalis, convexiusculus, nitidus, elytris apicalibus late rufis ; 
fronte stria integra medio retro-acuminata; pronoto bifoveolato, 
stria laterali basi abbreviata ; elytris striis 1-5 integris, suturali 
ante medium abbreviata. 
L. 33 mill. 
Oval, little convex, black, with the apical portion of the 
elytra broadly red; the head, frontal stria complete and in 
the middle drawn back to a sharp point; the thorax with a 
fovea and stria like those of H/. bimaculatus, L., but the 
latter is more abbreviated ; the elytra, striae 1-5 complete, also 
internal subhumeral, sutural apical and occupying two thirds 
of the elytral length, the fifth stria at the base turns towards 
the scutellum much more conspicuously than the corresponding 
stria in Hf. bimaculatus; the propygidium and pygidium have 
a few scattered and fine punctures ; the sternal plates are 
much wider than those of H. biémaculatus, otherwise they are 
similar. The anterior tibia has one large and wide apical 
tooth and four little ones behind it. 
The great differences between this and the Linnean species 
bimaculatus lie in its short and broad-oval form, the form of 
the frontal stria, and the more markedly inturned fifth dorsal 
stria.

CoPROXENUS, gen. nov. 
Body rather convex, broadly or shortly oval; head small, 
retractile, forehead impressed, clypeus transverse, mandibles 
equal and dentate; antenne, the club is oval and its fossa 
deep and in the anterior angle; the thorax is transverse, at 
the sides narrowing from the hind to the fore angle; the 
scutellum small and triangular; the elytra strongly carinate 
on the lateral edge (this carina takes the place of the usual 
external subhumeral stria), the internal subhumeral is also sub- 
stituted by a carina less strong; the dorsal striz are strong, 
and, in the two species known, complete, except the fifth ; 
the pygidia are formed like those in Pelorurus ; the proster- 
num is incised at the base, keel more or less wide, bistriate ; 
the mesosternum anteriorly acuminate, with a strong marginal 
stria and a transverse crenulate one; the metasternum late-
