222 THE entomologist's record. 



merit a careful examination. No precisely similar specimens seem to 

 have been taken elsewhere. I thought it not anlil<ely that they were 

 hermaphrodites, and determined to procure some more this year to 

 settle the point. Mr. Newman kindly promised to help and we each 

 found three, one of which was lost afterwards. Mr. Marshall also 

 obtained a specimen with one forewing almost entirely of male colour 

 and very much smaller than the other. This was handed over to me 

 for investigation. In addition I procured a specimen with wings 

 equal in size but showing streaks of brilliant blue on the right fore- 

 Avmg and left hindwing. Mr. Newman obtained a less well marked 

 example of the same kind. All except this last were carefully dissected 

 under water in the fresh state and the chitinous portions were then 

 softened in potash and examined while still soft. They were then 

 mounted after dehydration and clearing and reexamined under the 

 microscope. The following are detailed descriptions of these specimens 

 and bring out some n-jw and unexpected facts. 



No. 1. 



Both wings on right side small. 



Expanse. Right forewing 15 4mm., left 16-6mm. 



Right side shows small patches of blue scales chiefl}^ near the anal 

 angle of forewing, near apex and just internal to the central spot. 



Four or five androconial scales found. 



Hindwing scattered blue scales all round, but none in central 

 portion. 



Left side no blue scales on forewing and only a few at extreme 

 base of hindwing. 



The blue scales are nearly all rounded at extremity, as in the male, 

 and they are accompanied b}' the coarse pale blue hair scales peculiar to 

 the male. 



Ovaries, oviduct, ductus seminalis, receptaculum seminis, cement 

 glands and bursa copulatrix identified and found to be normal. In 

 mounted specimen chitinous structures, ovipositors, etc., recognised and 

 found to be normal. No trace of any male structure present. 



No. 2. 



Both wings on the left side small. 



Expanse of right forewing 16*2min., left 15-5mm. 



Patches of blue scales along posterior margin, near ajDex, and just 

 internal to central spot of forewing on left side, no blue scales on 

 right forewing. 



Some blue scales on both hindwings, but no more on left than 

 right. 



No androconial scales found. 



Underside : Two small spots at base of left forewing, one at base 

 of right, otherwise symmetrical. 



Ovaries normal in size, but lower parts contained no ova. 

 Oviduct normal, but devoid of ova. 



Ductus seminalis, receptaculum seminis, cement glands and bursa 

 copulatrix normal. 



No male organs present. 



Ovipositor and other structures normal ; no part of male armature 

 present.
