Thanatopsyche, n. g. 

 Aspect and coloration of Tlii/ridopteryx, but with 

 entirely different neuration ; primaries with the costal 

 vein ei^ending to second third of the costal margin ; 

 subcostal emitting its first two branches just before the 

 end of the cell which projects forwards at its anterior 

 angle, considerably in advance of its posterior angle ; 

 third subcostal branch emitted from the anterior angle, 

 forking just before the middle and emitting the upper 

 radial from its inferior edge, close to its origin ; lower 

 radial emitted near to the third subcostal, thus reducing 

 the upper disco-cellular to about half a millimetre in 

 length ; lower disco-cellular long and inangled, with 

 scarcely a trace of the usual recurrent spur ; median 

 four-branched, the third branch being forked from its 

 basal third ; submedian with short recurrent spur at 

 external third ; secondaries with powerful frenum and 

 several short stiff basal bristles ; no costal vein, its 

 place being occupied by the subcostal, which is arched, 

 and forks just before aj)ex ; cell large and broad, 

 projecting farther behind than in front, partly divided 

 by two short recurrent spurs, the first from an acute 

 angle near the commencement of the upper disco- 

 cellular, the other from the radial which separates the 

 oblique line of the disco-cellulars in the middle ; median 

 vein four-branched, the third branch being forked from 

 just above the middle, the branches all divergent so 

 that the first branch converges towards the submedian ; 

 antennae tapering, pectinated to the tips ; body densely 

 clothed with long hair; genitalia prominent and exposed; 

 femora woolly, sericeous ; tibiae and tarsi slender. 



Pupa-case elongate-fusiform, of densely-woven silk 

 mixed with small wooden chips, which give it a spotted 

 appearance, and just below the middle ornamented with 

 a zone of short projecting sticks. 



14. Thanato-psyche canescens, n. s. (Plate I., figs. 4, 4 a). 



Allied to Psyclie chilensis of Philippi, with which I 

 at first identified it, but differing, according to Mr. 

 Edmonds, in its smaller size and the paler colouring of 

 the thorax. Black ; wings semitransparent, with black 

 veins and margins ; head and antennae black, thorax 

 clothed with sericeous straggling grey hairs ; abdomen
