470 Mr. P. Cameron's descriptions of new genera 



Dolcrus qffinis. 



?. Of similar colour to D. ephippiatus, Sm., but 

 smaller; antennae shorter, thinner; underside of thorax; 

 bluish-black, not reddish ; a black spot in front of meso- 

 notum; head a little more closely punctured; feet, head 

 and breast not so pilose, and wings a little darker. 



IJab. — China. 



Dineura (?) africana. 



i. Black; antenniii jnlose, 3rd joint longer than 4th, 

 basal joint large, I'urnished at base with a short white 

 peduncle. Head large; clypeus small and very deeply 

 incised ; labrum large, hairy; palpi white. Thorax smooth, 

 shining, tegulas black; a spot below the wings white. 

 Legs Avhite, posterior tarsi fiiscous. "Wings half smoky; 

 marginal nerviu-e received a little past the middle of third 

 submarginal cellule ; first recurrent nervure received near 

 the middle of second submarginal cellule, and second 

 recurrent near the apex of third submarginal cellule; third 

 submarginal cellule considerably dilated. Posterior wings 

 with two middle cellules; anterior wings with neuration of 

 Ulennocampa. 



Length 6 lines.
