middle of a space away from ants brood, it is still, larger than 

 on entering nest, is dark in coloiir, with onc portion of darker, 

 but hardly black, thcrc is no sign of in jury by ants, eithcr before 

 or aftcr dcath. Aie on m Nos. i and 2 arc not perhaps quite as 

 large as they wcre, but look well, thcy arc more oftcn at cdge 

 of brood than in it, no proof that they arc feedmg, récent 

 addition of brood makes finding of dead ant larvae indecisive. 



May ci h. Larvae (2) of aie oit look rather bettcr than they 

 did, but do not grovv and there are no clear indications that 

 they fecd, thcy seem a little plumpcr howevcr and are more rosy 

 (less dark), they measure about 4.5 mm. long. 



A good many ova in nest to which g added April gth. 



May ijth. Alcon larvae in No. i, when nest was uncovered 

 was seized in the usual way by an ant and carried off, it carried 

 with it a full-grown ant larva, which the alcon held by its legs 

 and apparently jaws, and did not drop it until it came m full 

 collision against an impediment (pièce of sponge). The alcon 

 larva looked well and seemed a little larger than recently. 

 Récent measurements hâve been 5 mm. slightly under than over. 



May i8th. Alcon larvae looking better, plumper, segments 

 full and rounded and incisions well-marked, and colour paler. 

 This improvement in the alcon larvae coincides with two points 

 in their surroundings, the température has been much higher for 

 some days in my room, to-day, e. g. 71° (21.6" Cent). Pre- 

 viously it was very low never up to 60^ (15.5° Cent), oftener 

 50"-54« (io«-i2° Cent.). The other change, perhaps also dépen- 

 dent on the température, is that the ant larvae appear to be about 

 fully grown, having till recently been, though in last instar, 

 only about half -grown. 



May zôth. The alcon larvae look plump and fat and palcr 

 and are nearer 7 mm. long than 6 mm., and are more active than 

 they were, bending and reaching about. The ants still carry 

 them about when the nest is disturbed by letting in light. The
