V. — Descriptions of a new Genus and some new Species of Ho- 

 mopterous Insects from the East in the Collection of the British 

 Museum. By Adam White, Assistant Zool. Dep. Brit. Mus. 



Ancyra, White. 



A new genus seemingly allied to Eurymela, from which it may 

 be at once distinguished by the shape of its head;, which has not 

 the dilated cheeks (see magnified fig. of face), so prominent a 

 character in the New Holland genus. I can detect in Ancyra no 

 stemmata. The antennae are situated close under the eyes. Hem- 

 elytra finely veined, with a notch on the lower margin ; at the end 

 they are rounded and have a sort of knob, from which, in the 

 male, proceeds a longish narrow appendage, widest at the end, 

 and somewhat resembling the feathers on the head of Pteroglossus 

 ulocomus. Wings somewhat falcated, especially at the ends, which 

 are pointed and hooked. The legs are much dilated and com- 

 pressed throughout ; hind legs very long, with four spines on the 

 outer edge of tibia. Body at the end covered with a somewhat 

 waxy down-hke secretion. 



The species [Ancyra appendiculatd) is of a rich deep brown 

 colour ; the hemelytra above are brown, spotted at the base with
