GEN. DIASTELLOPALPUS, Lansb. 



DlASTELLOPALPUS OBBIGXYI, 11. Sp. 



Male : Black, shiny, almost glabrous on the upper side, pectus, 

 legs and under side of prothorax clothed with fulvous hairs, pygidium 

 and abdominal segments with shorter sub-flavescent ones ; antennae 

 yellow with the exception of the three basal joints which are piceous- 

 red ; clypeus broadly arcuate in front with the margin entire and 

 reflexed, genae hardly prominent, in the centre, in a line with the 

 suture at the junction of the genae there is a high, laminate, sharply 

 and broadly triangular keel the moderately rounded basal angles of 

 which are continued towards the frontal part as a sloping ridge set 

 at right angles with the clypeal carina and partly enclosing two deep 

 impressions the separating wall of which is continued as a short 

 median ridge reaching almost a transverse high laminate ridge set 

 on the vertex, truncate at both ends, reaching the median part of the 

 eyes and longer therefore than the clypeal which is widely separated 

 from the genac ; the surface of the clypeus is strongly transverse!}" 

 plicate, the frontal part and the genas roughly punctate ; the prothorax 

 is broader than long, almost vertical in front, and with the anterior 

 angles much produced, deeply excavated on each side, Copris-like, 

 while the central part of the apex projects as a broadly triangular 

 ridge the outer angles of which are continued vertically also as a sharp 

 ridge strongly dentate towards its median part, the lateral anterior 

 excavation has a sharp, short tooth on the outer part, close to the 

 lateral smooth impression ; the two lateral anterior excavations, and 

 also the median space edged by the two vertical ridges are sparingly 

 and not deeply punctate, on the upper part the anterior projection is 

 granular, the sides scabrose, the posterior median part is not closely 

 punctate, and the long, hind depression along the sides and part of 

 the carinate base is faintly punctate, there is no median smooth longi- 

 tudinal line ; elytra shorter than the prothorax and equally broad at 

 their widest part, plainly striate, intervals deeply and closely punctate, 

 each puncture bearing a very minute black hair, alternate intervals 

 wider than the others ; pygidium longer than broad, covered with 

 punctures similar to those on the elytra, but bearing each a much 

 longer and fulvous hair. 



Mons. d'Orbigny informs me that this species comes very near 

 I), tridepressus, Orb., but differs by the more shiny upper side, the 

 very short setose hairs on the elytra, the clypeal carina curving 

 behind at each end, and the frontal part with a depression on each
