444 LEPIDOPTÉROLOGIE COMPARÉE 



are very distinct and, with their yellow ûlling in, stand out clearly 

 just as they do in lafponarïa, they are broader than in that 

 species and so is the edging, although it is still broken and dot- 

 like as in zonaria. The subdorsal and supraspiracular stripes, 

 which in lapponaria are very narrow and practically obsolète on 

 the thoracic and last abdomnial segments, are a little more 

 strongly developed, but they are narrow and the edging is very 

 irregular. On the whole, the longitudinal stripes bear a close 

 resemblance to those of zonaria. 



The yellow transverse bars, too, are présent and are very much 

 like those of lapponaria in appearance, as they are somtwnat broad 

 and seem to be protubérances of the dorsal stripe rather than 

 bars. They are perfectly edged with black and may appear in 

 a reduced form on the 6th and /th abdominal segments. 



The collar, although somewhat beaded in appearance, is like 

 that of lapponaria. 



The anal plate is more rounded than that of that species and 

 is less black dotted ; the two larger spots on it bearing hairs are 

 absent but the four terminal tubercles are very distinct. Before 

 the anal plate are the two yellow spots of lapponaria and before 

 thèse agam, the two larger warts, although in a reduced form. 

 The blackish shades before the yellow bars are there too. 



The spiracular stripe, which m lapponaria is distinct only 

 beneath the spiracles and practically absent elsewhere, in sinall- 

 niani becomes broad and regular and possesses a fine black edging. 

 Above it, but m rare cases within in it, are the rounded black 

 spiracles. Thèse are more often in the blackish suifusion derived 

 from lapponaria. The stripe is much brighter yellow than in 

 zonaria, and in it can be seen, the yellow lapponaria spots. 



The underside of the larva, both in the appearance of the 

 stripes and in the whole scheme of coloration, is very close to 

 that of lapponaria, except that the médian stripes are broader, 

 a little further apart, and neatly filled in with yellow, as in 

 zonaria. The legs and prolegs are also lapponaria like. 



The larvae are variable, but the variation is practically restricted
