LÉPIDOPTÉROLOGIE COMPARÉE 41; 



of the influence of fouionaria than before, for it is more rounded 

 than in zonar'm and the lobing is fairly well indicated. 



Boly. The colour resembles the cool grey of sonaria rather 

 than the somewhat blackish grey of fomonaria. This causes 

 the larva to hâve a superficial resemblance to zonaria at first 

 sight but the présence of the fine yellow transverse bars of 

 pomonaria soon dispels this illusion, as do many other minor 

 points derived from pomonaria. The most striking omission of 

 a pomonaria character is the almost total suppression of the dark 

 suffusion after the yellow bars. The longitudmal stripes, 

 although narrower, are as in zonaria. The filling in of thèse 

 more resembles that found in pomonaria, as it is grey, instead of 

 yellow. The yellow bars are somewhat reduced, as one might 

 expect, but the yellow spot on the supraspiracular stripe in still 

 majrkedly distinct. There is présent the spiracular stripe of 

 zonaria, but in a reduced form. Showing clearly on its paler 

 primrose surface, are the yellow spots of pomonaria. The spi- 

 racles, which are just above the stripe, are black. 



The collar is fairly continuous, and is not at ail dot like, as 

 that of zonaria is. 



Owing to the great development of the black markmgs, the 

 anal plate seems blackish now but a few pale marks are présent. 

 Posteriorly, although not so rounded in shape, it is white edged 

 like the plate in zonaria larva. 



Just before this plate, we hâve the two yellow spots of pomo- 

 naria and, in front of them, the two warts, developed in the 

 gênera Lycia and Pœcilopsis. Ventrally, the larva is blackish 

 and bears two medioventral stripes very like, but not so yellow 

 as, those of pomonaria. Between the spiracular stripe and thèse, 

 just as in pomonaria, there are traces of a subspiracular stripe. 

 The legs are black, freckled with yellowish at the base. The 

 prolegs are blackish too, but tend to become lighter anteriorly. 

 The anal prolegs spread a little more than in zonaria.
