Imago. — ^$. Upperside of body and fore wing grey, the 

 hind wing and dark markings of fore wing and abdomen walnut- 

 brown ; underside of body and first segment of palpus greyish- 

 white : wings pale walnut-brown with grey base. Fore wing 

 above with distinct white discocellular dot lying in the anterior 

 broad portion of the antemedian transverse band ; between 

 the lower radial and upper median branches a longitudinal 

 streak, connected with the transverse band and distal! y 

 reaching an elliptical submarginal spot ; between the cell and 

 margin four transverse lines, the first two of which are more 

 or less confluent, the third one slightly developed, the fourth 

 widened anteriorly and here connected with the broad apical 

 oblique stripe. Hind wing with whitish-grey markings 

 before the hind margin and at the anal angle. Distal margin 

 of fore wing not undulate as in the two preceding species, 

 shallowly sinuate before posterior angle. Second segment 

 of palpus rather smaller than in the other species. Row 2 

 of spines of first segment of hind tarsus extending close to the 

 base as in Psilogramma. Expanse : 106-150 mm. 



$. Tenth tergite (fig. 12 A) divided into two long and 

 slender processes, which are regularly curved downwards and 

 gradually narrowed to a point ; the processes approach each 

 other a little in middle ; the sternite produced into a long 

 cylindrical process, which is slightly bent downwards at end, 

 the apex obtuse. Clasper sole-shaped, dorsal margin bent 

 inwards ; the large clay-coloured patch of modified scales 

 on the outer side consisting of large, multidentate, ribbed 

 scales ; harpe (fig. 12 B) ladle-shaped, minutely dentate ; 

 subdorsal longitudinal groove of clasper sharply defined, 

 deep, the fold below it with long bristles. Penis-sheath 

 (fig. 12 C) with one pointed process, which is rather broad at 

 base. Eighth tergite without friction-scales on the inner 

 surface. 



o. Vaginal plate (fig. 12 D) very feebly chitinized, the whole 

 post vaginal part membranaceous and scaled, the ante vaginal
