June i^lh. No. 2. Alcon bcing in a favourable position for 

 measurement, vvas found to bc 10 mm. long, more rathcr than 

 less. 



}ime iSth. (6.30 p. m. Greenwich Time). No. i alcon was 

 found lying on lus back with his hcad bent down towards 

 abdominal aspect of about ist abdominal segment, and held 

 between his head and body there appcarcd about one-third 

 (i/3rd) of an ant larva, thc remaindcr obviously eaten (or 

 collapsed fom contents being sucked). 



June 22nd. No. 2 alcon seen on his sidc with head pressed 

 close to ventral surface about 3rd thoracic, as if holding there 

 somethmg he was eating, the portion of ant larva, if so, had 

 become too small to project into view. 



June 2^th. Both larvae hâve the skms very tense and shining. 

 One measured yesterday was 1 1 mm. long. It is rather ludicrous 

 to see the ants endeavouring to move about thèse larvae so much 

 larger and heavier than themselves, in which, however, they are 

 not altogether unsuccessful. No search for alcon frass or 

 remams of sucked ant larvae, as numerous as found in the 

 autumn, has had any success ; it may be mentioned than an ant 

 pupa half-eaten (or sucked) at least damagcd and collapsed 

 was seen close to alcon larva, who had no doubt been eating it, 

 but his actual contact with it was not seen, uncovering the 

 nest &c. had no doubt disturbed it before it was noticed. 



]um zôth. No. 2 alcon quite straight measured 12 mm., not 

 stretched, as its tense skin would obviously admit of little 

 stretching. No. i with a slight curve measured 1 1 mm. 



]une 2Qth. Both larvae happening" to be favourably placed 

 for the purpose were measured and found to be 12 mm. long 

 in each case, the tint is decidedly paler than it was, may be 

 described as pale flesh-coloured, the skin seems less tense than 

 a week or two ago ; the incisions are not so decp, suggesting 

 that the skin has grown and stretched.
