570 PEOCEEDINGS OF THE AMERICAN ACADEMY. 



The hairs above are brown-black, while low down on the sides of the 

 body, on the head and prothorax, they are whitish. 



The dorsal setae are rather stout, with slightly marked short spinules, 

 while the setae of the lateral tubercules (supraspiracular and infraspi- 

 racular series) are slenderer, with longer delicate spinules, and longer 

 than in Telea polyphernus, Stage I, being about three times as long as 

 the tubercle itself. 



Brahmaea japonica Butler. 



A number of pupae from Japan of this interesting monogeneric type 

 were obtained by purchase, and Mr. Joutel kindly mated the moths, thus 

 obtaining a supply of the eggs, from which the larvae were reared by 

 him and myself in all stages. The eggs were laid in April, and the larvae 

 hatched April 27, while I received them alive (four examples) April 28. 

 They fed on the privet and lilac, and throve well in Providence on the 

 latter plant. 



Eggs. — Rather high, somewhat conical, with a broad, flattened base 

 and the apex a little depressed. It thus differs from the somewhat flat- 

 tened eggs of Ceratocampidae, and from the ovo-cylindrical eggs of the 

 Saturniidae ; apparently presenting striking family differences. The 

 shell is seen under a strong lens to be finely pitted. 



Larva. — Stage I. Length 9-12 mm. Width of head li mm. Head 

 small, no wider than the body, smooth, jet-black, polished and shining ; 

 with scattered long hairs. Body elongated, rather slender compared with 

 Ceratocampid larvae of this stage ; the body does not taper behind. On 

 the trunk segments (thoracic and abdominal) are six rows of small black 

 tubercles scarcely higher than they are thick, and giving rise to from 7 

 to 8 hlack hairs about as long as one-third the diameter of the body. 

 The tubercles on the 1st thoracic segment are no larger than those on 

 the abdominal segments ; on this segment they are situated on a black 

 cervical shield, forming a transverse black band, somewhat contracted in 

 the middle. 



Four large, long, thoracic dorsal horns, all of equal length, a pair 

 on the 2d, and another pair on the 3d thoracic segment. They are 

 each about one-fifth to one-quarter as long as the body, all of the same 

 shape and thickness, scarcely tapering to the end, which is blunt, black- 

 brownish at the end, flexible, not stiff, rigid and chitinous, and furnished 

 with numerous long fine hairs, which are of nearly equal length ; those 

 at the end almost forming a pencil or brush ; each hair very finely 

 spinulated.
