This species was taken by M. Raffray many years ago, 
and named P. Bocandet for me by Marseul and it stands in 
several collections under that name. But lately I have 
received the true P. Bocande?, Mars., from the Congo River 
and Senegal region and find that it differs from those taken by 
Raffray. P. Bocande?, Mars., has the clypeus deeply exca- 
vated, the thorax wider anteriorly and more coarsely punctate, 
but, above all, the prosternal strie in P. j‘rater are parallel to 
each other, while in P. Bocandei the strie through the whole 
of their course incline towards each other. P. Bocande? also 
is the larger species and has the anterior thoracic angles more 
prominent. 
Hab. Abyssinia and Zanzibar (Raffray). 
Pachycrerus meridianus, sp. 0. 
Oblongo-ovalis, parum cylindricus, niger, nitidus; capite stria 
antice interrupta ; pronoto punctulato, parcis punctis intermixtis ; 
elytris, striis 1-4 suturalique integris, 5 abbreviata; prosterno 
bistriato, striis haud conjunctis; mesosterno stria marginali 
integra, stria transversa crenulata. 
L. 23 mill. 
Oblong-oval, somewhat cylindrical, black, shining; the 
head not impressed or excavated, not closely punctulate, 
points varying in size, stria angulate at the eyes, but the 
transverse portion is wanting; the thorax evenly, not very 
closely punctate, with small points intermixed, the larger 
punctures are larger than those on the head, marginal stria 
ceases behind the neck; the elytra—strie, external sub- 
humeral very fine and complete, internal faint and dimidiate, 
1-4 and sutural complete, 5 punctiform and extending just 
beyond the middle, near the apices are scattered punctures ; 
the propygidium is sparsely punctured ; the pygidium much 
more finely punctured ; the prosternum bistriate, striz diver- 
ging at the base, not joining anteriorly, but diverging very 
slightly ; the mesosternum is irregularly punctured and the 
stria complete, and rather closely behind it is a very distinct 
transverse, crenulate, arched stria; it appears to be in front 
of the metasternal suture, which is only very faintly visible. 
There is a superficial similarity between this species and 
P. facetus, Mars., but it is smaller, and the prosternal striae 
and other characters serve easily to separate it.
