 ventral ly, or rather shrinking of ventral aspect, so as to bruig 

 the end to a ventral aspect. 



July loth. (4 p. m.). No. 2 alcon is found to bave moulted 

 to pupa. Thcrc is a dark substance over the last segment, which 

 is probably the cast skm, and at this an ant is tugging, whether 

 to help the moult of for what purpose is doubtful. 



5 p. m. The pupa stiU bas the cast skm (?) attached and bas 

 been moved a matter of 70 mm. by the ant or ants, but is at 

 présent at rest but with three ants m attendance. 



Not feeling clear as to the relation of ants and pupae and 

 with suspicion that the larvae, having for some days been at a 

 distance from the brood nest, were really seeking a place aw^ay 

 from the ants in which to pupate, I bave barricaded each of the 

 pupae in a corner of the nest where the ants cannot reach them, 

 this may or may not prove to be a proper proceeding. 



It is certainly difîicult to believe that the fat, léthargie larva, 

 stift and helpless by the tense distension of its skm could by 

 its own efforts hnd a suitable pupanum inside or outside the 

 ants' nest, but it is the case that the wandering of the larva 

 from the brood nest during the last week or ten days was 

 assisted, if not entirely managed by the ants. It is also, of 

 course, the fact, that my observation nests affordcd no suitable 

 place apart from that occupied by the ants, whether it was to 

 be reached by the larva's own efforts or by the assistance or 

 complète management of the ants.

 become of an olive-brown colour. No. i is only slightly darker 

 than at first, both bave the last segment more bent very ventrad, 

 so that the medio-ventral line of the abdomen beyond appen- 

 dages is very short as usual in Lycaenids.
