450 LEPIDOPTEROLOGIE COMPAREE 



On thc thorax, thèse lines are représentée! by a séries of small 

 whitish spots which ma y appear but more feebly, on the last 

 abdominal segments. In hïrtaria thèse are scarcely visible. 



The SLipraspiracular lines in both are very weak, and can be 

 seen before and after the spot, developed very early in this région. 



The transverse bars are neater and smaller than m hirtaria. and 

 are of a brighter yellow colour. The collar in bidoveci, instead 

 of being formed by brighter yellow spots at the ends of the 

 stripes, is continuons, for thèse spots are joined up. The anal 

 plate is darker and not so heavily built as in hirtaria. The 

 posterior margin is paler and bears, like that of hirtaria, four 

 black warts, emitting hairs. The two spots before this, instead 

 of remaining distinct as in hirtaria, become linear and are more 

 or less connected in bnloveci. 



Along the position of the spiracular line is a séries of large 

 yellow spots. Thèse are very différent from the round spots of 

 hirtaria, for they are pearshaped and the narrow portion points 

 upward. Beneath thèse, and in contact with them, is the weak 

 pale spiracular line appearing much stronger and decidedly 

 yellow before thèse spots, which are well developed on the thorax 

 and more faintly on the last abdominal segments. Thèse spots 

 are much stronger than in Jitrtarïa. 



Ventrally, the larva is deep black, only intcrrupted by the 

 longitudinal lines and the yellow subspiracular spots. The medio- 

 ventral stripes much resemble those of denhami and are thus 

 rather more indistinct than in zonaria. Thèse lines are but faintly 

 seen in Jnrtaria. In both Jùrtaria and bnloveci, there are slight 

 traces of the subspiracular stripe. 



In build the larva is distinctly nearer to that of the larvae of 

 the genus Ithysia than to Jàrtarïa. 



3rd INSTAR. 



Length at end : 14,5 mm. 



Even to the naked eye, the larva now seems much lighter in 

 colour, although the head differs but little from that of hirtaria
