Description of a New Genus and 3 new species 

 ofMalcididae trom South Aîriea. (Bym.) 



By P. Cameron. 



Centrochalcis gen. nov. 



Antennae lougisb, slender, of uniform thickness, the 

 scape slender, its apex reaching to the ocelli, its base broadly, 

 the apex uarrowly dilated; 12-jointed; the 2 n d joint (pedicle) 

 almost the longest, almost twice the length of the 3 r d, which 

 is hardly half the length of the #h ; the last joint hollowed 

 below. Scutellum large, its apex euding in two large, obli- 

 quely pointed teeth, which become "Tadually narrowed ; 

 sides of median segment armed with 2 stout teeth, uuited 

 at the bottom. First abdominal segment large, as long as 

 the following 3 uuited ; the 2nd aboufc oue third of its length; 

 the ovipositor broad, projecting. Hind femora with a broad 

 tooth behind the middle ; the apex broadly round ly dilated. 



Allied to Euclialcis aud Neochalcis. Stomatoceros, an 

 African genus resembles it in some respects, e. g. iu the 

 spotted wings; but the femora are not toothed beneath; and 

 the sides of the median segment are unarmed. 



1. Centrochalcis octodentata sp. nov. Q. 



Black ; the antennae reddish, darker towards the apex. 

 Malar space long, almost as loug as the eyes, which con- 

 verge slightly above. Inner orbits covered closely with 

 stout, raised tubercles, which are mostly • broader thau long 

 and are arrauged iu longitudinal rows, which extend to the 

 lower ocellus ; above they are closely rugose. Malar space 

 coarsely, closely rugose. Ou ter orbits covered closely with 

 raised tubercles, Upper part of thorax closely covered with 

 round, clearly separated puuctures of almost uniform size. 

 Metanotum at the base with 3 rows of reticulations ; the 

 central area is about 3 times longer thau wide and extends 

 to the apex of the 2ud row. Upper part of propleurae 

 covered with longish puuctures. Central part of mesopleurae 

 striated closely, the Striae becomiug weaker below. Meta- 

 pleurae closely, coarsely reticulated ; the upper lateral tooth 

 is stouter, longer and more rouudly narrowed at the apex
