50 PACHYTERIA VANDEPOLLI. 



but very narrow groove, and the vertex of the head opa- 

 que in consequence of a very dense though fine sculpture; 

 the clypeus smooth and impunctate along the middle, pro- 

 vided with large punctures at the sides; the mandibles on 

 the outside and the space between the eyes and mandibles 

 sparsely punctured ; the punctures beyond the eyes placed 

 between longitudinal wrinkles: the undersurface of the head 

 transversely wrinkled. The antennae rather short and thick, 

 not quite reaching the narrow ochreous band in the dark 

 coloured half of the elytra; the scape is short and thick, 

 above rugose , beneath strongly punctured ; the 3rd joint 

 equal in length to the 4th and 5th joints taken together, 

 the 4th joint distinctly shorter than the 5th , the subse- 

 quent joints slightly decreasing in length. 



The prothorax armed on each side behind the middle 

 with a rounded tubercle which is separated from the disk 

 by a narrow groove; the disk coarsely sculptured, the pu- 

 bescent parts opaque ; the sides glossy , sparsely punctured ; 

 beneath transversely wrinkled. The scutellum broadly trian- 

 gular with curvilinear sides , densely and irregularly sculp- 

 tured. 



The elytra parallel, conjointly rounded at the apex, and 

 provided with three faint longitudinal costae ; the ochreous 

 basal half densely and irregularly punctured , whereas the 

 sculpture of the dark apical half is very fine and dense. 



The anterior and intermediate femora are covered with 

 large and deep punctures , which are not densely set ; the 

 posterior femora are very densely punctured on the out- 

 side, much sparser on the inside; the sculpture on the 

 tibiae is very fine and dense. 



The apical (5th) ventral segment is rounded at the tip 

 and provided with a few punctures on the apical half. 



The described female specimen originates from Malacca 

 and belongs to Dr. Baden's collection which is now in the 

 possession of Mr. Neervoort van de Poll to whom I dedi- 

 cate this pretty species.
