C0LIA8 EDUSA BRED IN OCTOBER, 1908. 291 



Cryptid ; it looks, in fact, like one of the Acoenitini. I unfortu- 

 nately only know the male. 



Palmerella nigral sp. nov. 

 Black ; a small squarish white spot immediately below the antennae 

 and the palpi white, the fore legs brownish testaceous in front ; wings 

 clear hyaline, the nervures and stigma black. <? . Length, 8 mm. 



Kuching, Borneo (John Hewitt, B.A.). 



Face and clypeus closely, rugosely punctured, the former almost 

 reticulated ; the front and vertex more closely and finely reticulated- 

 punctured. Flagellum of antennge fuscous, black above. Thorax, 

 except the lower part of the propleurae, closely, distinctly punctured ; 

 the scutellum more strongly than the mesonotum, the metanotum 

 still more strongly and more clearly reticulated ; the depression on 

 the propleurge striated below the middle. First abdominal segment 

 distinctly but not closely punctured ; the second closely and regularly 

 punctured ; the punctuation on the others becomes gradually weaker. 

 Legs shortly, thickly haired ; the coxae and femora rather strongly, 

 closely punctured ; the long spur of the hind tibiae reaches to the 

 middle of the metatarsus ; the apex of the third joint of the hind tarsi 

 and the fourth yellowish white. 



COLIAS EDUSA BRED IN OCTOBER, 1908. 

 By F. W. Frohawk, M.B.O.U., F.E.S. 



It may interest some of the readers of this Journal to know I 

 have succeeded in rearing a nice series of C. cdusa this autumn 

 from a female captured August 7th at Wallasea, Essex (recorded 

 in the September issue, p. 229). I find, on going over the set 

 specimens, which number sixty, just thirty are males and thirty 

 females. A few others of both sexes emerged, which I did not 

 set ; therefore the sexes produced were of about equal propor- 

 tion. Most of the females resemble the parent in having the 

 marginal spots reduced in both number and size, which are 

 almost absent in some. The central spots on the primaries are 

 larger than usual, and a few have the central blotch of the 

 secondaries exceptionally large, forming in two or three speci- 

 mens conspicuous variation. 



The eggs hatched at the end of August. The parent died 

 August 30th. The first larva spun up for pupation September 

 21st, and pupated on 23rd, followed by others daily. The first 

 imago (a male) emerged October 8th, followed by others of both 

 sexes daily during the following fortnight. 



All the specimens (excepting two or three not set) are of full 

 average size, owing to the fine warm weather during the feeding 

 up of the larvae and the emergence of the butterflies ; usually 

 late autumnal specimens are reduced in size by cold weather.
