30 LÉPIDOPTÉROLOGIE COMPARÉE 



darker edges. The labrum is rather paler, but possesses a similar 

 dark edging. The antennae are not long like those in hirlaria, 

 nor short and stout as pomonaria, but are midway between the 

 two. The eyes are set in black spots. 



Body. The body is stouter and shorter than hirtaria. 



The ground colour is grey, more or less mixed as in hirtaria 

 with dull purple; it may be wholly purple or even greyish white. 



The stripes, with their edging, are very clear. The medio-dorsal 

 stripes, after a yellow bar, are almost parai lel to the end of the 

 segment, when they gradually separate until the next bar is 

 reached. While parallel, thèse stripes are hlled m with yellow, 

 which, at the commencement of a segment, gradually passes into 

 orange, and then, when the two stripes are furthest apart, be- 

 comes paler again. Thèse stripes, like tlie rest, are very regular 

 and parallel on the thorax, except that breaks may occur at the 

 primary tubercles. The space between them at a segmentai 

 division, has a dark-shading. The medio-dorsal area has much 

 the same appearance on the thorax. On the whole, in the above 

 respects, the larva resembles that of pomonaria. The subdorsal 

 stripes, after a bar, are broad and yellow, gradually weakening 

 and disappearing at the anterior tubercles of the next segment, 

 the fillmg — in becoming more orange in the process. They con- 

 tinue then very veakly until the next bar is reached. On the 

 thorax, and also on the last abdominal segments, where they are 

 very narrow they are rather regular. The upper edging is strong 

 and even, but that on the lower edge is somewhat ragged. In the 

 space before and after the bars, and more particularly before, is 

 a black suffusion, which is présent at a similar position on the 

 other segments. 



The supraspiracular stripes are very even near the end of the 

 segments, but tend to weaken until the bars are reached. On the 

 last segments they are very much confused. As was mentioned 

 before, the dorsal area is like pomonaria but the remainder of the 

 stripes follow hirtaria in build, and pomonaria in coloration. 



The collar is quite distinct — much more so than in pomonaria
