388 MR. A. G. BCTLER ON NEW LEPIDOPTERA. [Apr. 2, 



with more acuminate primaries; above bright stramineous, the 

 external area densely irrorated with red-brown scales, but leaving 

 clear yellow patches or spots behind a submarginal series of small 

 black spots, which are partly united by a zigzag dusky line ; a 

 straight dark brown stripe from the apex of primaries to the middle 

 of the abdominal margin of secondaries ; a very irregular dark brown 

 line across the basal area ; a small tricoloured ocellus (white, black, 

 and yellow) with hyaline centre in the middle of each wing ; pri- 

 maries with the basal half of costal border lilacine grey, a broad 

 dark brown longitudinal belt from the base to the straight oblique 

 discal stripe, an irregular dentate-sinuate brown line from the costa 

 to the inner margin just beyond the ocellus, a curved dark brown 

 streak from the costa to the oblique stripe, two grey- edged apical 

 white spots ; secondaries with a regular dentate-sinuate brown line 

 just beyond the ocellus ; head, collar, and tegulse grey ; palpi and 

 prothorax plum-coloured : wings below altogether paler than above, 

 the markings less defined, the dark longitudinal belt of primaries 

 obsolete ; body below pale yellow, the anterior tibiae and tarsi plum- 

 coloured. Expanse 3 inches 8 lines. Ambriz (Monteiro). 

 We also have what seems to be a faded example of this species 

 from Lake Nyassa ; the latter, however, differs somewhat in mark- 

 ing, and may prove to be locally constant. 



Attacus, Linnaeus. 



20. Attacus pryeri, n. sp. 



Allied to A. walkeri of Felder from N. China, but darker than 

 any of the species of the A. cynthia group ; olive brown, with paler 

 borders and the usual submarginal lines ; the pale belt (bounding 

 the dark angulated central line externally) white inwardly, pinky 

 whitish and diffused outwardly, with no defined intersecting stripe 

 as in all the allied species ; the maggot-like markings, basai white 

 belts, and the apical markings of primaries as in A. walkeri. Ex- 

 panse, 3 5 inches 10 lines, $ 6 inches 2 lines. 



Yokohama (Jonas). 



This species is the most undeniably distinct of all the forms allied 

 to A. cynthia. I name it after Mr. II. Pryer, of Yokohama. 

 Attacus cynthia, as figured by Drury, does not agree with Felder's 

 Chinese species, but is certainly nearest to the form occurring in 

 Java, to which Mr. Moore has given the name of A. insularis. It 

 may eventually prove to be distinct from the latter, from which it 

 appears to differ in the more angulated central transverse line ; in 

 all other characters, such as colour, the strongly dentate pale belt, 

 and the bent form of the maggot-like marking of the primaries, it is 

 extremely like the Javan form.
