shining beneath, the four basal dorsal seoments witli an 

 apical band of silver pubescence. Pygidial area shining, 

 strongly and rather closely punctured, without pubescence, 

 elongate, pointed at the apex. Comb of the fore tarsi long 

 and well developed; tarsal ungues long as in the genus 

 Notogonia. Third abscissa of the radius distinctly longer 

 than the second, the distance between the two recurrent 

 nervures on the cubitus scarcely more than half as great as 

 that between the first recurrent and the first transverse 

 culntal nervures. 



The male has the seventh dorsal segment closely but not 

 coarsely punctured, the punctures more or less confluent 

 longitudinally, and the median segment is granulate on the 

 dorsal surface.

May be distinguished from hypoleius, Sni., by tlie sculpture 

 of the median segment and pygidial area, the longer tarsal 

 ungues, and the lesser distance between the recurrent 

 nervures. But there seems to be considerable variation in 

 the development of the sculpture of the median segment, 

 which in some specimens is almost as smooth as in hypAeius.

To this genus must be assigned Gastrosericus neavei, Turn. 

 (Trans. Ent. Soc. London, 1912 [1913]), which, however, is 

 quite distinct from the typical species P. africana. The 

 generic distinctions given seem to me rather slight in view of 

 the aberrant structure of some species of Gastrosericus.
