LÉPIDOPTÉROLOGIE COMPARÉE 405 



Teratological spécimen. 



The spécimen figured on PI. A, Fig. 14, except, for the absence 

 of the right hind wing, is quite normal. 



Genitalia. 



1. Mâle (PI. J, Fig. 31). The uncus is not so broad as in /nr- 

 tarïa nor even relatively so. 



The valves are more like those of hirtaria on the costal margin, 

 but on the outer margin, they are convex like pomonaria. The 

 tendency displayed by hirtaria to be indented at the tip is not 

 markedly shown. The costal ridge is very slightly raised like that 

 of potnonaria. 



The gnathos is narrow and somewhat pointed and, although 

 influenced by the broad one of pomonaria, is nearer to hirtaria. 

 It surface however, is more like that in pomonaria. The œdeagus 

 is very short and as in hirtaria is thickened at the sides. The 

 cornuti form a very prominent band of closely packed spines, 

 vvhich, although very like those on the vcsica of pomonaria, are 

 even stronger than in that form. 



IL Female. There is little to be said about the génital organs 

 of the female, except that both the ovipositor and its sheath are 

 nearly alike in ail three forms except in size, and in this the hybrid 

 is intermediate. 



Habits of imagines. 



The imagines émerge a little earlier than those of the parents, 

 but the sexes do so at the same time, the usual time being the first 

 and second weeks in April, although if forced, they can be made 

 to émerge early in January. They leave the pupae at the same time 

 as ail the others, that is to say, late in the afternoon. Neither sex 

 displays a lack of instinct to climb, for they do so at once and 

 proceed to expand their wings. However, as the females are some-
