 aa. Bristling hair extended farthest upon the posterior radius and anterior 

 pobrachial, but very nearly as far on the cubitus ; much less extended on 

 the anterior radius. Third joint in the $ antenna narrower and barely 

 longer than the 2nd, and provided (in addition to a few subappressed 

 scales) with an incomplete verticil of long wide-spreading hairs. Superior

aaa Bristling hair extended farthest upon the cubitus; its endings on the 

 radial branches subopposite each other. Third joint in the S antenna 

 shorter than the 2nd, and provided with an incomplete verticil of hair 

 spreading widely on one side. Superior J genital appendages op. clt.,

B. Wing narrower, elongate-ovale ; apex subacute or rounded between the cubitus 

 and the praebrachial nervure; endings of the bristling hair on the 

 pobrachial branches and postical nervure either in an oblique straight 

 line or hardly perceptible salient curve with one another ; those on the 

 radial branches less or not farther advanced than that on the cubitus, 

 which is the outermost. Antennae in the S similar in construction to 

 those of No. 10, Brit, (described above), but with the first three joints 

 subequal in length to one another. 

 b. Endings of the bristling hair on the radial branches opposite each other, and 

 a little less advanced than its ending on the cubitus...

First and 3rd joints in the J antennae each much longer than the 2nd joint, 

 clad very densely with scales, and furnished in addition with long flattened hairs 

 that spread a little beyond their extremities ; 1st joint obovoid, slightly compressed, 

 broader than the 2nd, which is globose ; 3rd joint elongate-oval, narrower than the 

 preceding, and provided above on the outer side with three long spreading spinules 

 in a longitudinal row inserted respectively, one close to the base, and two nearer 

 together towards the apex of the joint. The remaining joints moniliform, with 

 hairs only, in verticils that attain their greatest amplitude at the oth joint ; some of 

 them with a pair of slightly curved, subulate or linear-lanceolate, articular append- 

 ages inserted not quite midway between the verticil of hairs and the end of the 

 joint; 4th joint inserted at the extremity of the 3rd joint; 4th — 11th joints 

 Bubacutely ovoid, not beaked ; 12th — 15th joints oval, in close contact with the 16th 

 which is bulbose. Outer limits of the region of bristling hair on the wings light 

 coloured, skirted from the radius to the anal nervure by a narrow greyish fascia, with
