210 THE CANADIAN ENTOMOLOGIST. 



parti-coloured hairs, the basal third of each hair being black, the upper 

 two-thirds white. The maroon tentacle with its long hairs spread out 

 like a circular fan or rosette is whirled round with great rapidity in a 

 plane parallel to the body, its use being almost certainly to frighten away 

 its enemies, as this larva, as far as I am aware, is not attended by pro- 

 tecting ants and lacks the honey-gland on the eleventh segment present 

 in so many lycaenid larvpe which are affected by ants." 



Ants have been found attendant upon half a dozen genera, and in 

 many cases they have been identified by Dr. A. Forel, of Switzerland. 

 At least a dozen species are concerned, and they are about equally 

 divided between the Formicidse ^nd Myrmicidje. 



Spalgis, it appears, is another instance of a carnivorous lycgenid com- 

 parable to our Feniseca, the larva associating with and feeding upon the 

 " mealy bug " of the planters, a species of Dactylopius. De Niceville in 

 no way favors Edwards's belief that Feniseca belongs to the Lemoniinse, 

 and adds nothing, as we had hoped he might be able to do, to Holland's 

 suggestion that Liphyra, too, might be carnivorous, though he points out 

 that the two genera differ in their perfect state in the number of subcostal 

 nervules, and are therefore not so closely allied as Dr. Holland thought. 



The seasonal dimorphism of many Indian Lycaenidae is well brought 

 out, the dry and wet season taking the place of our spring and summer ; 

 indeed, it occurs in no less than eighteen genera, and this will be a revel- 

 ation to many, and seems to bid fair to renovate the study of tropical 

 butterflies. But while in India proper, " the seasonal forms seem to be 

 chiefly restricted to two, a wet and a dry," in the Himalayan district of 

 Sikkim " the dry season form which occurs at the end of the year differs 

 somewhat from the dry season form which occurs in the spring, so that 

 with regard to some species there may be said to be three forms — a 

 spring, a wet season, and a winter form." Sexual dimorphism on the 

 contrary is very rare among tropical Lycsenidae, de Niceville stating that 

 he does not know positively of any case, though he suspects it in a species 

 of Zephyrus. On the authority of Doherty (a native of Cincinnati by the 

 way, working most industriously in the east,) he credits half a dozen or 

 more species as mimicking others of the same or neighboring groups of 

 Lycsenidse. Much attention is also paid to the secondary sexual char- 

 acteristics so far as their gross appearances are concerned, and they are 

 noted in no less than nineteen genera.
