LÉPIDOPTÉROLOGIE COMPARÉE 395 



the thorax. Just before the yellow spots, is a deep black clouding, 

 containing the black shiny spiracles. The first and the last of 

 the spiracles are the largest. Below the line is a yellow spot, 

 more or less continued forward, as in -pomonaria, as an obscure 

 longitudmal stripe with edging complète. In many cases, the 

 black clouding between this and the spu'acular stripe, so conspi- 

 cuous in pomonaria, is absent in this hybrid, thus anticipating 

 what holds good ni the last poînonaria histar. 



The two yellow spots before the anal plate bearing two of the 

 primary tubercles together with the two warts on segment 8, 

 are very distmct. The anal plaie now is doser to that of hirtaria. 

 In colour, it is black, pale-raarbled, the posterior edge being paler 

 but bearmg the four usual warts and setae. The plate on the anal 

 claspers is a mixture of black and dull yellow, more decidedly 

 yellow behind and before. The other prolegs are paler. 



The legs are black with paler rings and be?r laterally the 

 remains of a subspiracular stiipe. In gênerai appearance, they 

 resemble pomonaria but the paler areas are pinkish tinged. The 

 underside of the larva is ornamented much as in pomonaria. 

 There is the medio-ventral séries of barrels formnig the two 

 œntral stripes, with a broad space between like pomonaria. This 

 causes the medio-ventral stripes to approach the subspiracular 

 stripes; thus the spaces between thèse are narrower than in hirtaria. 

 The edging, however, is more hirtaria like.

Length at end 42 mm. 



Head 3,4 mm. 



5th abdominal segment 4,8 mm. 



Head. In shape, the head very closely resembles pomonaria 

 for, in proportion, it is broader than long, owing to the fui 1er 

 epicranil lobes. The inclination to notching, which is quite per- 

 ceptible in hirtaria, is very slightly shown hère. 



The colour is yellow, more or less purplish, clouded and heavily 

 marbled with black. The mouth parts are yellow-brown with
