LÉPIDOPTÉROLOGIE COMPARÉE 413 



ï) The fringes may be paler spotted. 

 7) The hindwings are slightly larger. 

 Wing expanse : 39-42 mm. 



II. Female (PL CLXII, Fig. 1576). The females of kunii and 

 ■pilsii are very like each other but usually, when of the same size, 

 those of hîiftii are paler. For the most part however, kunii Q Q 

 are much smaller and the wings more linear; otherwise, except 

 for the more sharply eut appearance of the smaller spécimens, 

 and the greater tendency of the fringers and costa to be provided 

 with bristles, there is but little différence. A typical short-winged 

 hunii Q, is figured on PL A, Fig. 12. 

 Wing expanse : 24-30 mm. 



The variation in both sexes, on a smaller scale, is the same as in 

 pïlzii. It is not necessary therefore to repeat the discussion hère. 



Genitalia. 



I. Male (PL J, Fig. 32). The influence of fomonaria is the 

 greater in deciding the genitalia in this forrn, although both sets, 

 except for the superior power of hirtaria in the formation of the 

 gnathos in pilzit, are nearer pomonaria. The valves are narrower 

 than in pilzii and the costal ridge slightly raised as in pomonaria. 

 The gnathos is less pointed and, therefore, broader and more 

 rounded. The cornuti are exceedlingly well developed, even sur- 

 passing in this respect some examples of pomonaria. 



II. Female. There is absolutely no différence in the genitalia 

 of pilzii Q and hunii Q- 



Teratological spécimen. 



I hâve one male, normal in gênerai appearance, but with a 

 circular hole in the cell of the right forewing. 



Habits of imagines. 



The imagines of both forms behave the same both in regard to 

 émergence, pairing and the other points; it is well, however, to
