marginal area, and an aberration of woak coloration, due in all 

 probability to lack of pigment in the scales. 



On behalf of Mr. Arthur Dicksee, Dr. E. A. Cockayne exhibited— 



1. Homoeosis in Papilio horishanus male, from Formosa. On 

 the underside of the left forewing, between nervure 4 and 5, is a 

 patch of the brilliant red and black of the underside of the 



hindwing. 



2. Aberration of male of P. thaiwamis, from Formosa, together 

 with a normal male and female. Instead of the hindwing being 

 rounded it is of the squarer shape of the female, but even more pro- 

 nounced, and it shows a greater attempt at a tail. 



3. Eight specimens of ^.^/r/fls aimjdon and of A. wuzomsis, from 

 Colombia. They prove that Friihstorfer in Seitz is wrong in stating 

 that the female never has a blue mark on the hindwing. In some 

 of these the blue mark is very distinct, and blue scales are present 

 in all except one. He is also incorrect in stating that the female 

 tvom Brazil is the only one with red on the hindwing. Red is 

 present in more than half the series. 



Colonel R. H. Rattray exhibited Cupulo winiimoi ab. semiobsoleta, 

 a g with only five spots showing on the front wings. A g with 

 striation commencing ; while the forewings are normal the spots 

 on hindwings show a tendency to lengthen out. Ab. striata. A <? 

 exactly similar to one taken by Mr. Joy m 1905. The forewings are 

 absolutely without any trace of spots. The hindwings have on lower 

 margin four black streaks of considerable but varying lengths, and one 

 line very black on basal costal area, no other spot showing on hmd- 

 wings. " It was taken on June 4th, 1922. Plebeius aeqan ab. duplex, 

 a 9 ''showing on each side a different tint of female colour, the right 

 side of both wings strongly marked with light blue, the left a dark 

 fuscous without any blue scales ; it is not gynandrous. Another 

 example, but not so strongly marked, was taken the same day 

 within a few yards of this one. A pathological specimen with all 

 four wings symmetrically light grey coloured, the underside mark- 

 ings showing through very plainly, taken in 1921 on same ground 

 as last shown. Agriades thetis [bellanjus) ab. addenda <? , a <? 

 with a patch of emerald green on the basal area of forewings. This 

 specimen was taken home alive in a pillbox and killed with cyanide, 

 leaving it in bottle not more than twenty minutes, nor was it pos- 

 sible for any damp to have got at the specimen. A g with a large 

 oval bar of a dark leaden colour across each forewing. These bars 

 are almost symmetrical. Examined under a high power of the
