new Species of Histeride. 183 
Pachycrerus Spaviosus, Sp. N. 
Ovalis, parum depressus, niger, nitidus ; elytris obscure eeneo-nigris ; 
capite impresso, stria integra ; pronoto stria marginali late inter- 
rupta. 
L. 4 mill. 
Oval, rather depressed, black, shining, with the elytra 
feebly eneous; the head is rather narrower than in P. cyan- 
escens, Hir., but the form of the stria and the frontal impres- 
sion are similar allowing for the width, the punctuation is 
slightly closer; the thorax is also like Krichson’s species in 
punctuation and in the lateral stria ceasing behind the eye ; 
the elytra, strie 1-3 complete, 4-5 coequal, apical and about 
3 of elytral length, sutural very short, terminating anteriorly 
in a line with the fourth and fifth, subhumeral external 
dimidiate; the propygidium and pygidium are punctured 
somewhat similarly to P. cyanescens, but the punctures are of 
a slightly smaller grade and the segments are flatter; the 
prosternum is wide and the striz are parallel to each other 
and terminate at the suture behind the anterior lobe; the 
keel is as wide again as that in P. cyanescens, and with the 
lobe is punctulate ; the mesosternum, marginal stria complete, 
but very fine at the space behind the keel; the anterior tibie 
are somewhat slender and have three or four small teeth. 
The species in some of its characters is intermediate 
between P. cyanescens and P. latus, Lew. 
Hab, Cameroon. 
Pachycrerus cariniceps, sp. n. 
Oblongo-ovatus, parum conyvexus, obscure rufo-brunneus; capite 
punctulato, stria carinata ; pronoto utrinque sinuato, stria laterali 
carinata, angulis anticis subfoveolatis; elytris, striis 1-4 et 
suturali completis, 5 apicali. 
L, 22 mill. 
Oblong-oval, rather convex above, obscure reddish brown, 
shining ; the head obscurely and sparsely punctulate, frontal 
stria complete and cariniform, the carina 1s the least strong on 
the middle of the anterior edge, the clypeus is transversely 
concave at the base, with a strong ridge dividing the concave 
part from the anterior portion; the thorax subfoveolate at the 
anterior angle, distinctly sinuous laterally before the base, 
_ the lateral stria cariniform, carina strongest at the sinuosity, 
stria complete but fine and crenulate behind the head, surface 
somewhat sparsely and finely punctulate; the elytra—strie,
