22 me. p. cameron on tiie [May 7, 



has a narrow furrow down the centre. Clypeus transverse in the 

 middle; its sides broadly rounded. Mandibles black; the base 

 thickly covered with greyish pile : the middle rufous. Palpi black, 

 covered with a grey pile. The sides of the pronotum behind are 

 straight and oblique. The median segment is distinctly furrowed 

 down the middle. The cloud in the fore wings commences at the 

 end of the radial cellule ; the radial cellule is wide in the middle ; 

 the apical abscissa of the radius is oblique ; the apical half has a 

 different angle from the basal. The spines on the tibia? and 

 tarsi are black ; the calcaria are two-thirds the length of the 

 metatarsus. The first and third transverse cubital nervures are 

 roundly curved ; the second straight and slightly oblique ; at the 

 top the second cubital cellule is not quite half the length of 

 the first. 



Comes near to P. pulvtrosm >Sm., which may be known from it 

 by the" cloud commencing " beyond the first submarginal cell," and 

 the calcaria are nearly as long as the metatarsus. The description 

 of P. pulverosus is not very complete. A revision of the Hymeno- 

 ptera collected by Dr. A. li. Wallace in the Malay region, and now 

 in the Hope Museum, Oxford, is a great desideratum. At present 

 the determination of many of the species from the description is 

 mere guesswork. With the Larridce, for example, one is never 

 certain whether the species described belongs to Larnt, Notoyonia, 

 Tachygpheaa, or TachytesJ]

Antenna? rufous ; the scape hollowed on the underside : the 

 outer edge is much sharper than the inner ; the apical joints are 

 roundly curved above. The head fulvous ; the face pale yellow ; 

 the vertex (especially at the ocelli) fuscous black. Eyes large, 

 slightly converging above ; the lower part parallel ; the ocelli 

 large, placed in a triangle, the hinder are separated from each 

 other by a slightly greater distance than they are from the eyes ; 

 there is a narrow shallow furrow in the middle of the front. Pro- 

 thorax rufo-fulvous ; the lower and hinder parts of the pleura? 

 darker coloured. The apical half of the mesonotum, the scutellum, 

 and postscutellum are rufo-fulvous ; the black on the mesonotum 

 is triangularly narrowed at the apex. Median segment, except at 

 the apex, transversely striated ; it is covered with a golden down 

 and som:( longish pale fulvous hairs. The scutellum is thickly 

 covered with long pale fulvous hair. Legs rufo-fulvous : the 

 hinder coxa? black ; the inner tooth of the claws is half the length 

 of the outer. Wings fulvo-hyaline at the base ; the apex with an 

 obscure violaceous-fuscous tinge, which is deeper in the radial and 

 cubital cellules ; the discoidal cellule is hyaline, with an elongated
