﻿LÉPIDOPTEROLOGIE COMPAREE 



colour is a lively rose, slightly darker perhaps than " La 

 France ". Not quite what Ridgeway calls La France Pink 

 (3. o. R. f.) but nearer an nitermcdiate between his Deep Rose 

 Pink and Rose Colour (71 V-RR d & 6). 



May 2çth. Larvae much the same, fatter if anything; though 

 they must be 6 or seven times the bulk not leitgth, &c., they were 

 at end of winter, nothing has yet been traced as to how they 

 feed, they are not seen feeding, no sucked out ant larvae are 

 found in midden, nor is any alcon frass detected. 



June ist. Each of the two larvae is now 9 mm. long, looks 

 as if it might moult soon, the skin being stretched and the 

 incisions expanded and opened. Nothing has been observed to 

 shew how they are fed, one is inclined to suspect that the ants 

 feed them, as there is no direct or other évidence that they eat 

 or suck the ant larvae. The ants are well supplied with dead 

 diptera and honey, and their own larvae are many of them very 

 large and fat. 



Jtine yd. No. 2 nest larva of alcon is seen with head in 

 ventral sinus of a full grown ant larva; and its thoracic seg- 

 ments curved round the ant larva, so that it holds it partly by 

 this grasp round it, partly probably by its jaws. Curiously 

 a sucked ant larva is found in the midden of this nest; though 

 none hâve been found for many weeks, though looked for 

 whenever nests examined. The skin of alcon larva looks very 

 tight and glazed. 



Jiine I2th. Tarvae much the same, one when rather extended 

 was 10 mm., the skin is very tense smooth and shining, and 

 there is a dépression but no fold or overlap at the incisions. 

 To-day it is noticed that both Larva i and Larva 2 are not with 

 the mass of the brood, but at a separate point, away from brood 

 in No. 2 and with some smallcr ant larvae in No. i. There are, 

 however, a fair share of ants in attendance in both cases.
