50 THE ENTOMOLOGIST. 



is sunken, the micropyle finely reticulated. There are about 

 twenty strongly developed longitudinal keels, eight of which run 

 the entire length, starting at the edge of the micropyle, where 

 they rise high above the surface ; others start about one-fourth 

 down, and run to the base, which is flattened ; the intervening 

 spaces, which are deeply concaved, are transversely ribbed by 

 about fifteen in number ; the surface is finely pitted. 



Mr, Eothschild informs me, when first laid, the eggs are "a 

 very pale straw-colour, but get gradually darker." This is the 

 case with all the Argynnidae eggs. When they first reached me 

 some had already assumed two purplish zones, one at the crown, 

 the other near the base ; these gradually darken to a deep 

 purplish hue, especially near the crown, the basal one being 

 much paler. The rest of the egg is an olive ochreous colour, 

 excepting the extreme summit, which is transparent ; the colour- 

 ing changes with the maturing of the larva, which is apparently 

 well-developed by the beginning of October, when the above de- 

 scription was made. 



During winter the egg appears to deepen somewhat in colour, 

 and assuming a generally rather deeper purplish drab before 

 hatching. 



On examining the eggs February 19th, 1908, I found some 

 had just hatched, and others on the point of hatching. 



The larva^eats its way out by making a large hole in the side 

 of the shell. Directly after emergence it measures -^^ in. long. 

 It very closely resembles A. paphia in structure. The head is 

 shining olive-black, beset with pale ochreous, finely serrated 

 bristles ; on the first segment is a dark dorsal disc, each segment 

 bears a series of large warts, on the summit of each rises a long, 

 finely serrated, club-tipped ochreous brown bristle, with a shining 

 black and brown bulbous base ; the dorsal series of bristles are 

 in pairs, both situated on a large wart on each segment ; the 

 other two large globular subdorsal warts have each a single hair. 

 There are in all eight hairs and six warts on each segment above 

 the spiracles; below each of the latter is a large globose wart bear- 

 ing five long, fine serrated hairs projecting laterally; excepting 

 on the last three segments, all the dorsal hairs curve forwards, 

 while those on these last segments are straighter and project 

 backwards ; on the ventral surface, claspers, and legs are simple, 

 white, finely-pointed bristles. The entire body (including the 

 legs and claspers) is a pale olive-ochreous colour, densely covered 

 with extremely fine black points, producing a very fine granulated 

 surface. The colouring gradually becomes slightly darker when 

 a day or two old, and the large body-warts assume an olive- 

 green-grey hue. 



When touched they fall and roll up, remaining so for many 

 minutes. 



The young larva exactly resembles that of A. paphia in
