Ir. A. heliconia dicta f. extensa forma nov. 



This form is apparently much rarer tliau f. dirtu. As tijiie we take a specimen 

 in Dr. Statidinger's collection (from the Kina Balu, 1200 — 1500 m., Waterstradt 

 1892) which lias the following characters : It is similar to sucli Indian individnals 

 oi clacatn which liave the streak of the forowing wide and the marginal band to the 

 hindwing narrow. The white streak occupies on the npperside the posterior half of 

 the cell, reaches at vein 4 about 2 mm. beyond the apex of the cell, and extends 

 along vein 2 for mm., having at the apex, which is bisinnate, a width of nearly 

 6 mm. The border of the hindwing is from vein 6 to the anal angle very narrow, 

 measuring at that vein 2^ mm. and at vein 4 scarcely more than 1 mm. ; at veins 4 

 and 5 it is indented. The subcostal and submedian nervures are whitish in the basal 

 half of the forewing. 



In a male from Sarawak iu the Tring Museum the streak of the forewing is 

 slightly narrower, less obviously bisinnate, than in the before-described ? , and the 

 border of the hindwing is of nearly the same width as iu dicta f. dicta. In neither 

 the ? nor the S here mentioned is the abdominal region of the hindwing below 

 suffused with blackish scales.

c. A. heliconia nicobarica. 



Hyjisa nicnharica Swinhoe, Cat. Lep. Het. Oxf. I. p. 87. n. 387 (1892) (Great Nicobars). 



Differs from A. heliconia dicta f. dicta in the two outer black dots of the basal 

 yellow area of the forewing being merged together, thus forming a black border to 

 the yellow area. 



A specimen in Dr. Staudinger's collection has the veins in the basal half of the 

 wing faintly striped white, and there is a white angle-shaped spot behind the median 

 nervure outside the transverse black snbbasal line. The pro- and mesothorax have 

 black spots.

d. A. heliconia enganensis subsp. nov. 



S. Resembles A. heliconia dicta f. dicta from N. Borneo ; but the basal half of 

 the costa is deeper black, the three basal black dots at the costa scarcely visible : 

 the outer one of the two black dots behind the median nervule not angle-shaped, and 

 not encircled with white. The forewing has no wliite nervular lines ; the white 

 longitudinal streak is club-shaped as in dicta, and between veins 2 and 3 sinuate as 

 in clavata. Border of hindwnng above as broad as in dicta, extended a short distance 

 along the abdominal margin, with a faint blackish longitudinal line in tlie middle 

 extending straight from the base across the black cellular spot to the marginal band ; 

 the band a little dilated at the nervules. On the underside the basal portion of the 

 longitudinal mark of the forewing is obsolete ; hindwing with a broad black border 

 all round. Body bright orange above; abdominal black sjiots as in clavata ; anterior 

 pair of legs blackish. Our series of cf cf varies as follows: In one specimen the 

 white streak of the forowing is convex between veins 2 and 3 as in dicta, the longi- 

 tudinal median line of the hindwing above is much more heavily marked, and the 

 underside of the hindwing is for the greater part black, there remaining only a long
