LÉPIDOPTÉROLOGIE COMPARÉE 38/ 



and so is that part of the wing. The various lines and bands are 

 almost gone giving the wing a very washed-out appearance. 



The hind wing is quite normal on the costa and for the bulk 

 of its area but vein I, as it leaves the base, sweeps upward and 

 then down forming a semicircular ctirve. The portion of the 

 wing before this vein is suppressed. 



The fur on the right side of the thorax is affected too for it 

 is much smoother and more zonaria like than that on the left. 

 The colours also are more like the pure black and white of zonaria. 



B) Female. I. This female example was produced in the same 

 brood as the second maie spécimen. 



In it, the left wings and right forewing are ail normal, but as 

 can be seen from fig. 10, PI. A, the other wing is strangely formed. 



This is brought about by the curious distortion of the veins. 

 Vein I is longer than usual, but is not otherwise mal formed. 

 On the contrary, vein 2 is twice as long as usual, and takes a 

 bolder curve on its outward path. After vein 2 leaves it, the two 

 chief veins of the cell curve toward each other slightly and then, 

 when vein 3 passes off, it curves outward and downward to vein 



2 and practically forms the margin of the wing. Vein 4 is either 

 absent or included in the thickened vein 2. Vein 5 forms a curve 

 similar to that of vein 3 but upward, and seems fused to vein 6. 

 Vein 7 is normal except that it is produced outward twice as far 

 as usual. The costa, therefore, is larger than in a normal example 

 and, instead of being slightly convex, is concave. After reaching 

 the end of vein 8, the costa rapidly curves down to meet vein 5, 

 giving the upper part of the wing the outline of a bird's head. 



The portion of the wing between the transverse vein and veins 



3 and 5 is absent. 



Genitalia. 



I. Mâle (PI. I, Fig. 30). The maie genitalia are very much 

 the same as those of denhami but there is a distinctly marked 

 approach to zonaria not visible in that hybrid.
