410 A. S. PACKARD, JR., ON GYNANDROMORPHISM 



two deep scallops near the ocellus. The ocellus is more like that of the female than of the 

 male, the blue semicircle being much more distinct than in the normal male. 



The hind wings are marked and colored as in the anterior pair, with the submarginal row 

 of dumb-bell like spots obsolete and represented by faint x-eddish discolorations, being con- 

 colorous with the corresponding spots in the female. Beneath, the fore wings are as in the 

 male, not differing essentially in color. The hind wings have the white discal spot nearly 

 ol)solete, and the submarginal row of spots nearly obsolete, but concolorous when present. 

 The left wings are both female throughout, the markings rather more highly colored and 

 with larger and more distinct discal spots on both wings than in the normal female with 

 which I have compared it, but owing to the shortness of the wing, the extradiscal line is 

 nearer the apex of fore wing than in the normal male, and in the hind wings the same line 

 is a little beyond, rather than considerably within, the middle of the wing, as in the normal 

 female. Beneath, both wings only differ from those of the normal female in the larger, 

 better marked discal spots, the style of coloration being the same, except the difference in 

 situation of the common extradiscal line. 



The thorax and abdomen are reddish as in the female, except on the right half of the 

 thorax and basal half of the abdomen, which is blackish-brown, as in the male ; the blackish 

 discoloration does not, however, quite reach the median line of the body ; on the abdomen 

 it recedes from the median line rapidly towards the middle of the body. This dark color 

 extends beneath the insertion of the wings on to the side of the thorax, but there is a 

 broad red patch on the right side of the thorax, while the right side of the abdomen is 

 beneath entirely like the left side. The three pairs of legs are, on the right side, consider- 

 ably smaller than on the left. The tibiae are but little smaller, and differ in color from 

 those on the left side, being of a dull sable brown. The most striking difference, however, is 

 in the diminutive size of the tarsi, which are scarcely half as large as those of the left legs. 

 The five tarsal joints and the claws are present and well formed, but very short and small, 

 the entire tarsus of two front pairs of right legs not being much longer than the first 

 tarsal joint of the male (the tarsi of the third pair of legs are broken off). The inequal- 

 ity of the two anterior legs is shown in Plate xiv, fig. 1, c, d. The right tarsus is about 

 one-third shorter than the left ; the first and fifth joints being about one-half shorter than 

 in those of the opposite tarsus ; the second and third joints also shorter, Avhile the fourth 



is about the same. 



The abdomen is as large and well developed as in normal gravid females, and is distended 

 with eo-o-s equally on both sides, as, though the specimen is dried, I was able to pick out 

 with a sharp point an egg from each side, showing quite conclusively that the gynandromor- 

 phism has not affected the internal organs of generation. The eggs are of the normal size, 

 beinc .08 inch in diameter. They are easily seen through the abdomen as in other dried, 

 gravid females. 



The extenial appendages (fig. 1, h, c) are symmetrical and do not differ from those of 

 other normal females. The supra-anal bilobed plate is large, well developed and of the 

 normal form, and so is the less deeply bilobed infra-anal plate. The ovipositor Avithin con- 

 sists, as usual, of two well developed rough projections closely approximate and alike on 



both sides. 



As regards the external generative parts, then, the specimen is entirely female.
