joints. Front with six stiff bristles — a divergent pair at 

 the centre of the vertex, a single one on each side close to 

 the eyes, and one lower down above each antenna. Thorax 

 greatly arched, with three complete rows of small dorsal 

 bristles, and well-marked humeral, posthumeral, noto- 

 pleiiral, supraalar, and pcstalar bristles, scutcllum with 

 four long marginal bristles. Abdomen about equal in 

 breadth to, but a little longer than, the thorax, altogether 

 without bristles. Legs of medium length, bearing a few 

 bristles, the coxpe considerably lengthened. Wings large, 

 unusually broad, the costa strongly convex ; mediastinal 

 and subcostal veins anastomosed, cubital vein unforked ; 

 discal vein incomplete at the base, and with an incomplete 

 veinlet above; discal cell wanting; the basal cells short, 

 the first and second of equal length, the anal a little 

 shorter. 



The correct position of this curious genus is somewhat 

 doubtful. Notwithstanding the very different venation, I 

 am of opinion that it is allied to the genus Ironoinyla 

 previously described. The venation resembles that of the 

 genera Micromnki and Bicellaria, particular!}^ the latter, 

 but differs from that genus in having the second basal 

 cell only equal in length to, instead of much longer than, 

 the first basal cell. It differs so much, however, from 

 Bicellaria in the form of the antennae, the widely-separated 

 eyes of the female, and the shape of the wings, that I 

 am doubtful whether the resemblance in venation may 

 not be a misleading one. The genera Microsania anct 

 Bicellaria are placed by Lundbeck in the Hyhotince^ by 

 Melander in the Ocydromiincz; without wishing to ex- 

 press an opinion as to the correct position of these two 

 genera, I might mention that the new genus now de- 

 scribed seems to m© to show no relationship whatever with 

 the Ocydromiince, and that if it is referable to any of 

 the existing subfamilies, it can only be placed in the 

 HyhotincE. 



Only one species is at present known.
