LÉPIDOPTÉROLOGIE COMPARÉE 453 



clear but not so clear and grey as in hirtaria. Tlie ground between 

 the mediodorsal and the subdorsal stripes, just in front of the 

 yellow bars, is ûlled in with black, which does not shade off into 

 the ground as in hirtaria. The yellow bars are much weaker than 

 in hirtaria and not so regular. Fiurther, as they proceed outward, 

 they become narrower. The collar now consists merely of small 

 yellow spots at the end of the stripes. 



The anal plate is narrower and the colour much more yellow, 

 with heavier dark mottling, than in hirtaria. In front of it, are 

 the two yellow dash like marks with a small chitinous tubercle 

 emitting a hair. On segment 8, the two larger black warts are 

 fairly conspicuous. 



The spiracular stripe is provided with a black edging above, 

 and is somewhat regular. On it, are the large triangular spots, 

 the apex of which just touches the supraspiracular stripe. The 

 yellow spot on this stripe, which as in hirtaria^ has persisted 

 since the first instar, is connected with the spiracular stripe just 

 after the larger spots. The space containing the spiracles, and 

 the ground area near it, are blackish. The spiracles themselves, 

 are plainly larger than those of hirtaria. Ventrally, the larva 

 distinctly reminds one of zonaria larva. The medioventral 

 stripes are very broad and the hlling jn is pale, but the inner 

 edging is weak compared with the outer. So clear ly marked is 

 this tendency, that, on the early abdominal segments, the two 

 stripes are nearly one, and even elsewhere the inner edgings tend 

 to fuse. The subspiracular stripes are much nearer the médian 

 lines than in hirtaria and are thinner, more undulating, and 

 interrupted. The space between thèse and the spiracular stripes 

 is black, with faint paler frecklings. 



The legs are black, with paler markings, which stand out much 

 more clearly than the pinkish mottlings of hirtaria. The claws 

 are much shorter than in that form. The space between the legs 

 is yellow, and, just at the base of the legs, between it and the 

 spiracular stripe, is a rather conspicuous yellow bar. The prolegs, 

 which are quite evidently shorter than those of hirtaria, are pale
