at the abdominal margin. On the underside the yellow spots are deeper in tint 

 in honrathi, and tlie bliick colonr of the hindwing is decidedly more extended. 



?. The submarginal .spots of the upperside are smaller in honrathi than in 

 the first-described form of the species ; on the underside the spots of the forewing 

 are less yellow in honrafki, while the black colour of the hindwing is more 

 developed.

8. Coscinocera hercules. 



This insect, of which I have a series of eleven sj>ecimens from Queensland, 

 New Guinea, and New Ireland, has developed into three easily recognisable races, 

 which are distinguished from one another as follows : — 



a. C. hercules omphale Butler, Tr. E. Soc. Loud. p. 7 (1879) (N. Ireland). 



(?. Wings above much more reddish tawny than in the other two forms ; 

 white band in basal half of wings not bordered black outwardly ; postmediaii 

 white line not very clearly defined, of nearly the same width (2 mm.) throughout, 

 straight between the veins, its inner border darker than the ground-colour of the 

 wing, but not so black as in the races from New Guinea and Queensland. The 

 eye-spot of the forewing is irregularly elliptical, not pear-shaped, and has a 

 triangular hyaline centre the longer diameter of whicli (7 mm.) is jiarallel to the 

 postmedian baud, while the longer diameter of this hyaline spot is parallel to the 

 veins in the other races ; the hyaline spot in omplcale is encircled with white, upon 

 which follows a broad ochraceous ring (5 to 7 mm.), which is much more yellow 

 than the ground-colour of the wing and has a black otiter border. The distance 

 between eye-spot and postdisoal band is about .5 mm. The eye-spot of the hind- 

 wing is almost circular (width 13 mm.) ; the longer diameter of the hyaline centre 

 is again parallel to the postdiscal band ; colour the same as on forewing. On the 

 underside the size of the eye-spots is especially remarkable, the ochraceous ring 

 round the hyaline centre being .5 mm. wide midway between the veins.

S. Outer band of forewing much less white than in hercules hercules, con- 

 sisting of rather obscure whitish lunules, which are on the forewing widely separate 

 from one another and are inwardly bordered with brownish black. Basal band 

 outwardly with a brownish black Ijorder : the anterior luniform jiortiou of this band 

 stands at a distance of 13 mm. from the black outer ring of the eye-spot. The 

 eye-spots both of fore- and hindwing are very small, strongly triangular ; that of 

 the forewing reaches the postdiscal band, its clajnsh ochreons ring less bright 

 than in omphale, in li/pc from Dorey 2 mm. wide basally, in specimen I'rom German

 at an angle of about 45° to postdiscal band ; hyaline spot small, diameters 2 and 

 4 mm. respectively. Eye-spots on underside with the hyaline centre as above, but
