(3) Zijiiaena trifolii, Esp., a yellow aberration, one of the original 

 series taken by Mr. W. M. Christy in 1893, at Watergate. 



(4) Zyijaena filipendulic, L., a yellow aberration taken by Mr, C. 

 D. Head, at Tenby, ] 897 ; an aberration with confluent spots on 

 left forewings ; an aberration intermediate between yellow and red ; 

 and a fine bred example of the aberration chrysantlieuii, much 

 darker than usual. 



(5) A new phase of variation illustrated by twelve new forms 

 of Heliconius vielponione from French Guiana, taken between 

 the two places, St. Jean and St. Laurent, on the Maroni river. 

 These were named primus, J. & K., collis, J. & K., \nelpina, J. & K., 

 nei/roiila, J. & K,, maris, J. & K., faustalia, J. & K., elefjantula, J. & 

 K., eltriju//taiiii, J. & K., piinctarius, J. it K., majestica, J. k K., 

 Incimh'lla, J. & K., and stygianus, J. & K. The most remarkable 

 among these were primus, uiarls, and punctarius, which collectively 

 represented a wholly new phase of variation in vtelpomone, with a 

 conspicuous yellow spot within the cell. In describing all these 

 new forms it was pointed out that the end kept in view was that, as 

 the iiielj)omene forms divide up according as to whether they have 

 a hindwing with either (1) a black, (2) a red base, (3), a red base 

 and flame-streaks, it was necessary to describe each phase of the 

 forewing in each category of the hindwing as soon as it was known 

 to occur. In many instances this repetition is known to occur, but 

 in some few cases up till now the links are missing. For instance, 

 there is no known pure black -melpomeue. Yet it seems possible that 

 some day it may occur, for forms occur with all the discal forewing 

 colouring absent, and melpomene itself has of course a black hind- 

 wing, but till now absence of discal forewing colouring is only 

 known when the base of the forewing is red, when also at the same 

 time the hindwing is either red at base or flame-streaked in addi- 

 tion. Most of the forms named above were to be figured on a plate 

 to appear in the " Transactions of the Entomological Society of 

 London." (1916, p. 412, pts. cvii, cviii.) 



Mr. W. J. Kaye himself exhibited a large cabinet drawer containing 

 practically all the species of the Ithomiine genus, Leucutlnjris. The 

 genus was characteristically composed of transparent insects with 

 black markings, and a recurring feature was a black belt across the 

 cell of the forewing. Although the majority of the species were 

 thus coloured there was a small group that had developed a varying 

 amount of orange marking on the forewing. These species were 

 ■doubtless mimics of other Ithomiines, or species of other families.
