(? ? . Palpns triangular, pointed, differing markedly from that of tlie otber 

 species. Mernm of mid- and hiudcoxae somewhat angnlate. Spines of abdominal 

 tergites contignons, long and short ones almost regular!}' alternating ; those on 

 stemites much weaker and more numerous ; first sternite with spines. First 

 hindtarsal segment about two-thirds the length of the tibia, barely as long as 

 segments 2 to 4 together ; spurs shorter than in Jrei/s. 



Body and wings much darker than in Jims. Forewing with broad, 



interrupted or complete, paler median band, which is much broader at costal than 



at hinder margin, and includes the minute black stigma. Hindwing almost 



unicolorous, darker distally, without distinct bands. 



(J. Scent-organ of forecoxa small. Tenth tergite (PI. XLI. f. 22, dorsal view) 

 divided into two lobes, which are widely separated by a rounded sinns, the lobes 

 broad, slanting, somewhat twisted, apically roundedly excised ; sternite (Xv) also 

 produced into processes, which are, however, very much longer than the tergite 

 (Xt), and are internally dilated into a broad tooth. Clasper (PI. XLVI. f 1) rather 

 narrower than in Jiciia ; the harpe similar, but spines heavier, ajiex broader. 

 Penis-sheath (PI. LIII. f 11) obtuse, with some minute teeth at the left side ; 

 numerous spines within the sheath. 



?. Eighth tergite short, truncate, shallowly sinuate, membranaceous in 

 middle distally. Vaginal plate (PI. XL. f. 16) distally sharply defined, the apical 

 margin raised, angnlate mesial ly, continued basad, forming the border of a large, 

 mesial, rounded depression, in which is situated the rather small vaginal orifice ; 

 anterior edge of the orifice raised. Seventh sternite broader than long, trapeziform, 

 apex truncate, not membranaceous, no spines. 



Larva said to be like that oi fcxs, but larger {'i^. Brmninghansen describes 

 it as being lighter green than JJcxs, and becoming black with green belts shortly 

 before pupation. — Food-plants : Artocarpufi ; Fie us.

6 ? . Pale median interspace of forewing separated into two patches : one 

 costal, large, including the stigma, the other small, at hinder margin ; the two 

 patches seldom connected, but if so, the band thus formed strongly constricted ; the 

 posterior patch sometimes vestigial.
