ATTACDS. 



Id this genus 1 consider A. lorquini Feld. a good species instead of a suli- 

 8i)ecies of A. atlas (Linn.). I have three new species to describe : — 



Attacus dohertyi sp. uov. 



This species, of which I have three males, is somewhat intermediate between 

 A. edwardsi White and A. cratneri Feld. 



Foretcings : gronnd colour nearest to that of .1. crameri Feld., bnl diifers by its 

 more rosy tinge and the much larger vitreous spots in the middle of each wing. 

 Costa and base of the wing deep red, densely powdered with bine scales. 



The transverse band beyond the vitreous siJots consists, as in most members of 

 the genus, of four contiguous bands ; the inner one is black and very deeply and 

 distinctly deutated, the second is white, flic third is bright maroon red, and the 

 outer and broadest one is deep brown, densely powdered with blue scales. 



Outer margin half an inch wide, and clay brown, enclosing a black zigzag line, 

 changing to bright rose red at the apical third. 



Hinduings similar, but inside the submarginal line is a row of large bright 

 maroon red patches. 



Head, thorax, and abdomen rosy brown ; antennae very large, and with the 

 pectinations very long. 



Underside similar in marking to the upper, but ground colour pale clay brown 

 washed with grey, and the row of muroou spots within the submarginal line is 

 present in both pairs of wings. 



Expanse : 9 inches = 230 mm. 



Hub. Timor {t//pe) and Flores. 



Attacus aurantiacus sp. nov. 



Forewings rosy brownish orange, the transverse band composed of three con- 

 tiguous bars only, the inner one chocolate red, the second one white, and the outer 

 one twice as broad as in A. atlas (Linn.) and bright rose jiink, powdered with blue 

 scales on the outer edge. Costa blue grey. 



Hinduings similar. 



Vitreous patches in all four wings large and much nearer the base of the wings 

 than in any other Oriental species of Attacus. Outer margin of all the wings half 

 as wide as in A. dohertyi sp. nov., and much darker ; submarginal line red, and the 

 j)atches inside it rosy pink. 



Expanse: 11 inches = 280 mm. 



Hab. North West New Guinea (2 <?, 2 ? ). 



Attacus staudingeri sp. nov. 



This very remarkable species is nearest to A. edwardsi White, but in shape 

 reminds one forcibly oi Drepanoptera albida (Druce). 



Forewings narrow and very strongly curved, almost semicircular or sickle 

 shaped. Ground colour rich plum purple, washed with an olivaceous tinge. About 

 an inch from the base there is a rectangular elbowed tniusverse wliite band, and the 

 outer edge of the large triangular vitreous sj)ot is deeply bordered with olive yellow. 

 The transverse band beyond the vitreous patch is strongly angulated and dentated, 

 and consists of three contiguous bauds —first black, second white, and the outer one
