 attenuato, obtuso, squamis minutis an nulatis arete obtecto, subtusque villis adsperso; fceminae 

 quinque-articulatis, attenuatis, squamulis minutis annulatim ordinatis vestitis, subtus setis

Character. The larva and chrysalis as yet unknown. In the perfect insect : Antenna of mo- 

 derate length increasing gradually in thickness to a cylindrical club which tapers to a short 

 point ; basal portion with an obsolete internal groove transversely crenulated, while the extreme 

 joints are marked with minute bristles. Palpi straight, compressed, slender ; measuring one- 

 third at least the length of the antennae : basal joint short, closely applied to the head, covered 

 by a tuft of delicate silky hairs ; second joint long, oblong, projecting far beyond the head, 

 gradually tending upwards, closely covered underneath with silky hairs uniformly pointing 

 downwards; third joint slender, oblong, obtuse, pointing forward, covered with a very minute 

 short down. Proboscis broad, longer than the palpi, with short bristles at the extremity. 

 Head short, obtuse. Eyes not prominent, even, naked. Body short, acute. Wings : anterior 

 oblong, obtuse; posterior, attenuated towards the anal region, abruptly truncated, with a short 

 anal appendage and straight tails following the direction of the wings. Feet: anterior of the 

 male, with tarsi consisting of a single, subcylindrical, attenuated, obtuse joint, covered with 

 minute scales, arranged in alternate rings of different colours, among which, underneath, stiff 

 bristles are also scattered; the extremity being blunt, incurved, without claws, but provided 

 with several stiff bristles : of the female, with tarsi consisting of five joints, the first thick and 

 long, the rest gradually attenuated to the terminal one, which has two minute lateral claws, an 

 appendage on each side, and an intermediate pulvillus, all which are concealed by a transverse 

 series of hairs ; the general hairy covering, and the bristles underneath, are similar to those of 

 the males: the mid legs and hind legs, in both sexes are also provided with two minute claws, 

 resembling in their appendages, pulvilli, and general structure the anterior feet of the female.
