This species was taken by M. RafFray many years ago, 

 and named P. Bocandei for me by Marseul and it stands in 

 several collections under that name. But lately I have 

 received the true P. Bocandei^ Mars., from the Congo River 

 and Senegal region and find that it differs from those taken by 

 Eaffray. P. Bocandei, Mars., has the clypeus deeply exca- 

 vated, the thorax wider anteriorly and more coarsely punctate, 

 but, above all, the prosternal striae in P. frater are parallel to 

 each other, while in P. Bocandei the strije through the whole 

 of their course incline towards each other. P. Bocandei also 

 is the larger species and has the anterior thoracic angles more 

 prominent.

Pachycrwrus vieridianiis, sp. n. 



Oblongo-ovalis, parum cylindricus, niger, nitidus ; capita stria 

 antice interrupta ; pronoto puuctulato, parcis punctis intermixtis ; 

 elytris, striis 1-4 siituralique integris, 5 abbreviata ; prosterno 

 bistriato, striis baud coDJiinctis : mesosterno stria marginali 

 Integra, stria transversa crenulata. 



L. 2| 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, tlie larger 

 punctures are larger than those on the head, marginal stria 

 ceases behind the neck ; the elytra — stride, 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 presternum bistriate, strise 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 strise 

 and other characters serve easily to separate it.
