transverse rugae. This rough area varies a good deal in its extent. The 

 central line is divided at the base of the maxillae, and encloses a small 

 triangular portion, the base of which adjoins the labrum ; a little farther 

 down, on a line with the base of the eyes, the central line again divides, 

 and encloses a long narrow strip 4 mm. long and about 0-25 mm. across 

 at its greatest width. This area is a portion of the labial palpi, and is 

 divided by a central suture. The antennae show every joint very distinctly, 

 and are somewhat roughened. The scape of each antenna is square in

outline and plainly marked out. The prothorax lias a slight central suture 

 and a sculpturing of fine lines ; the posterio-lateral extremities are elongated, 

 forming 2 narrow tongues extending down alongside the antennae for 

 0*54 mm., the 1st spiracle being imprisoned in the angle so formed, the 

 posterior margin of the prothorax projecting over it like a lid just raised 

 from the aperture. The 1st legs have a narrow margin against the eyes 

 and antennae, are wide and large, the greatest width being 1-25 mm. 

 Between them and the maxillae is a small strip 1-74 mm. long, the 1st femur.

The 2nd leg is somewhat narrower than the 1st, both legs having a slight 

 transverse sculpturing. The mesothorax has an appreciable sculpturing 

 in labyrinthine wrinkling, and there is a well-marked central suture. The 

 wings are finely sculptured, and the nervures are easily seen. Poulton's 

 line is gracefully curved, and cuts oft* a fairly large triangular area. The 

 metathorax has a deep central suture, and is covered with fine labyrinthine 

 wrinkling. The narrow strip of the hindwing has its greatest width at the
