THE ENTOMOLOGIST S RECORD. 



<3hitinous tube, which ends in a thickened oval sac and lies folded 

 between the two ovaries. 



No. 6. 



Right forewing very much smaller than left ; right hindwing 

 slightly smaller. 



Expanse of right forewing 15mra., left 16mm. 



Right forewing almost covered with blue scales, the majority of 

 which have rounded extremities, others intermediate or sharply ser- 

 rated. The blue scales are not disposed in regular rows, but there are 

 numerous small gaps, where the underlying brown scales are exposed. 

 Coarse bluish-white hair scales are numerous in the situations where 

 they are found in the normal male forewing. Battledore or andro- 

 conial scales are present in great numbers, and in some places occur 

 even in the absence of the blue scales which normally overlie them. 

 In the right hindwing, which is almost as large as the left, there are 

 scattered blue scales arranged in three short lines, radiating from the 

 base. The wings on the left side are devoid of blue scales. There are 

 some long hairs on the right side of the abdomen near the tip. 



On dissection the ovaries were found to be of normal size and equal, 

 but the ova were rather irregularly arranged. The ova themselves 

 appeared to be normal. Some were in the common oviduct, as low as 

 the level of the entrance of the receptaculum seminis. Ductus semi- 

 nalis and receptaculum seminis, normal. Cement glands equal and 

 normal. Bursa copulatrix natural in size and shape. No male organs 

 present. Chitinous armature absolutely normal, being without trace 

 of male or deficiency of female structures. 



No. 7. 



The wings equal on both sides. On the right forewing there are 

 blue streaks, two running from the base to the outer margin of the 

 wing, and two running only a short distance. On the left hindwing, 

 the opposite side, there is a short streak of blue near the anterior 

 border. All the blue scales are broad and slightly serrated, and are 

 everywhere mixed with scales of similar shape, but of a deep indigo 

 blue or black colour, which form a marked contrast with the much 

 more serrated light brown scales of the rest of the wing. 



No male hair scales and no androconial scales were seen, though 

 the blue streak runs through a part of the wing, where the latter are 

 most abundant in the male. 



The genitalia, internal and external, were symmetrical and of 

 normal female form in all respects. No trace of male organs was 

 present. 



I have examined 31 similar specmiens caught in 1913, 21 with the 

 right wing small, nine with the left, and in all these I found coarse 

 bluish hair scales and androconia on the small forewings, and in one 

 case androconia also on the small hindwing. The remaining specimens 

 had the right wing smaller than the left, but both sides were much 

 dusted with blue, and on microscopical examination the male hair 

 scales and androconia were seen on both forewings, though more 

 numerous on the right. 



I will discuss the last specimen (no. 7) first. This, though splashed with 

 blue, shows none of the primary or secondary sexual characters peculiar
