184 Mr. G. Lewis on 
subhumeral internal dimidiate, 1-4 complete, Sapical, not quite 
reaching the middle, 6 complete and hamate near the scutel- 
lum; the propygidium clearly punctured; the pygidium 
much more finely punctured ; the prosternum, lateral striz 
gradually meet and join anteriorly ; the mesosternum, stria 
complete and sinuous in front ; the anterior tibia with three 
equidistant teeth and another smaller at the base. 
In general outline this species is most similar to P. facetus, 
Mars. 
Hab. Cameroon. 
Pachycrerus tenuistriatus, sp. n. 
Cylindricus, supra eeneus ; capite haud excavato, stria fronte inter- 
rupta, ante oculos utrinque foveolato; pronoto stria antice inter- 
rupta, ante scutellum impresso; elytris, striis 1-3 integris, 4 
brevi, 5 nulla, suturali ante basin abbreviata. 
L. 24 mill. 
Cylindrical, brassy above, black beneath, shining; the 
head not excavated nor impressed, microscopically punctured 
and strigose, stria angulate at the anterior edge of the eye, 
turning obliquely past a lobe-like fovea, and ceasing beyond 
it (¢. e. the transverse portion of the stria is obliterated) ; the 
lateral stria continues round the base of the head in a line 
with the hinder edge of the eye, the anterior edge of the 
clypeus is transverse and clothed with brownish hairs (perhaps 
in one sex only); the thorax rather sparsely punctulate, 
punctures of various sizes, lateral stria ceases behind the eye, 
in front of the scutellum is an impression more or less semi- 
circular, and near it a few punctures; the elytra—strice, sub- 
humeral external fine and complete, internal dimidiate, 1-3 
complete (3 in one example only visible at the base), 4 short, 
basal and slightly oblique, sutural crenulate, straight and 
shortened before the base, the apices sparsely punctured ; the 
propygidium clearly and sparsely punctured with a micro- 
scopic punctuation interspersed; the pygidium finely and 
sparsely punctulate; the prosternum microscopically strigose, 
with a few fine punctures, bistriate, strize barely reaching the 
base and diverging from one another at both ends; the meso- 
sternum sculptured like the prosternum, anterior edge without 
a stria, across near the base is a well-defined crenulate arched 
stria and beyond it the metasternal suture is faintly visible ; 
the anterior tibie 4- or 5-dentate.
