LÉPIDOPTÉROLOGIE COMPARÉE 393 



The large yellow spots on the spiracular line are présent, cau- 

 sing it to combine the distinctness of thèse spots in hirtaria with 

 the progress ponionaria niakes toward the possession of a dis- 

 tinct, if narrow, spiracular stripe. This development hirtaria 

 rarely shows in this instar. 



Beneath thèse large spots is another yellow spot, paler than 

 that of hirtaria, and best seen on the hrst abdominal segments 

 where it is large and round and not linear as in pomonaria. 



The small and indistinct spiracles are, like those of pomonaria, 

 situated m a blackish suffusion which however is never so dense 

 as in that species. Beneath, the two medio-ventral stripes are 

 well marked and there are scattered traces of the subspiracular 

 stripes and their edging. The coloration is much as in ponionaria, 

 but the space between the two chief stripes is shaped like that in 

 hirtaria. The legs are black with paler bases. 



The anal prolegs, although distinctly longer then they are 

 in a species like zonaria, are not so spreading as in hirtaria. The 

 posterior plates are dark-coloured with paler freckles, which 

 become more pronounced on the anterior parts of the claspers. 

 The other prolegs are more decidedly blackish but tend to be 

 paler within. 



As the larva grows in this instar it becomes more and more 

 like the adult form. 



4st INSTAR. 



Length at end 2,4 cm. 



Breadth 2,6 mm. 



Head 1,7 mm. 



Head. The head, perhaps, présents us with the most hirtaria 

 like characters in this instar for, instead of being grey, it is quite 

 purplish and is heavily black spotted. The maxillae, etc., are 

 dark m colour but the frons is paler edged. The antennge are 

 black tipped but the base seems somewhat purple. The usual 

 bristle appear on the primary tubercles. For the size of the larva, 

 the head seems rather small.
