recurved : hindwing sliort, apex pointed, exterior margin slightly sinuons and angular 

 in male; subcostal spur at one-half from base of cell, two subcostal branches from 

 end of the cell ; discocellular much recurved outward, radial from the middle ; cell 

 short, extending one-third the wing ; middle median at one-seventh and lower at 

 three- sevenths before end of the cell; submedian and internal veins slightly curved. 

 Body very robust, male with a slight tuft ; head slightly tufted between the antennae; 

 palpi convex in front ; legs and antennse moderate. 



ACOSMERYX CINEREA (Plate 89, Fig. 2, 2a, larva). 

 Acosmeryx Cinerea, Bntler, Proc. Zool. Soc. 1875, p. 245. 



Dark grey: forewing with three pale brown transverse subbasal equidistant 

 curved narrow bands, three discal and a less distinct submarginal sinuous band, a 

 broad oblique brown fascia crossing the latter from the costa to posterior angle, a 

 brown zigzag streak also below the apex, and a similar brighter streak from the costa 

 before the apex; a brown spot at end of the cell: hindwing with the apical area 

 broadly brown. Thorax streaked above, and abdomen with oblique lateral brown 

 streaks ; palpi and legs above brown. 



Expanse 3J to 3-^ inches. 



Larva pale olive-green, dorsally dotted with darker green; head small, anterior 

 segments depressed from the fifth towards the head, dilated laterally and edged by a 

 yellow-bordered black band ending at the ocellated spiracle on sides of fifth segment ; 

 a pale-bordered purple subdorsal band extending from head to horn ; below the band 

 the green is of an emerald tint and numerously white-dotted ; the spiracles black 

 ringed; below them on sixth to eleventh segment is an oblique green stripe; horn 

 purple, dotted with black; on fifth to eleventh segment is a dorsal purple-brown 

 yellowish-bordered mark. Pupa thick, blunt, spiked at each end ; reddish, paler

 Forewing narrow, apex falcate ; exterior margin convex in the middle, slightly 

 uneven ; posterior margin recurved, first subcostal emitted at one-third, and second

 immediately beyond the end; cell extending to half the wing; discocellular obliquely 

 concave, radial from near lower end ; middle median at one-fifth and lower at three- 

 fifths before end of the cell ; submedian and its basal branch very close together : 

 hindwing short, narrow, apex convexly pointed ; exterior margin recurved, pointed 

 at anal angle ; cell not extending to half the wing ; subcostal spur emitted at beyond
