Pygoccelis strigosifrons^ sp. n. 



Cylindricus, niger, nitidus ; fronte dense strigosa ; rostro apice 

 truncate, leviter sinuate ; pronoto ante medium partim strigoso ; 

 prosterno marginato ; pygidio valide punctate ; tibiis anticis 

 4-dentati8. 



L. 3^ mill. 



Cylindrical, black and shinino;; the head, tlie anterior part 

 is densely strigose with a small fovea on its vertex, behind 

 which there is a small smooth space ; tiie thorax is con- 

 spicuously sinuous at the sides with the lateral strise well- 

 marked, surface rather closely and coarsely punctured, 

 punctures sliallow and crescent-shaped anteriorly, others 

 before the middle but not close to the sides are strigose ; the 

 elytral punctures are less close and smaller ; the pygidiuna 

 is coarsely and densely subocellately punctured and in the 

 female but slightly concave on its disk ; the prosternum is as 

 long again as broad, marginate on its four sides and slightly 

 sinuous at the coxse, where the margin is reddish, the anterior 

 and posterior edges are both sinuous, the surface has some- 

 what shallow and elongate points; the mesosternum, the 

 anterior part projects somewhat in the middle and the marginal 

 stria is interrupted behind the prominence, the lateral margin 

 is reddish near the coxae, and on the surface the punctures are 

 relatively fewer and less close (yet evenly set) than those of 

 the prosternum and are more conspicuously cucuUate ; the 

 metasternum is similarly punctured ; the anterior tibiee are 

 4-dentate. 



The prosternum of this species is shorter than that of 

 P. africanus^ Lew., and the species is narrower and not so 

 large as P. usamhicus, Kolbe.
