" Just before Mr. Lamborn went away I brought in two 

 larvae of Myrina silenus, and have been watching the attendant 

 ants — a form of Camponotus akwapimensis, Mayr., — at work 

 on the gland. I have been comparing the behaviour of the 

 larvae with that described, on p. 488 of the 1913 Trans. Ent. 

 Soc, for Cupido malathana, Boisd., and have been greatly 

 interested. I noticed that the tubercles do not apparently 

 work with such great rapidity as in this latter species. For 

 considerable intervals they were not out at all ; then they 

 would be thrust out somewhat slowly and deliberately. The 

 ants in this case did not seem to mind them, but when the leg of 

 an ant that was sucking the gland secretion happened to touch 

 a tubercle accidentally, the latter was withdrawn with great 

 rapidity. Both are not withdrawn simultaneously. It is 

 curious to note, too, that when one ant is working on the 

 gland, alternately tapping with its antennae and sucking the 

 droplet as it appears, another ant or sometimes two would 

 go on tapping the larva at other parts of the body, apparently 

 with as great assiduity as if they were on the actual gland. 

 To the credit of the lucky worker, be it said that it shared, by 

 regurgitation, its meal with the others. For quite a long 

 interval no amount of tapping the gland produced any visible 

 effect, and during this time the tubercles were not inactive 

 but were thrust out at intervals. The ants seemed in some 

 perplexity, and three altogether vigorously tapped the larva 

 but with no apparent result. The ants seem, after a short 

 preliminary alarm, to have no objection to any one looking 

 on with a low-power lens.

" The ants went on tapping the Lycaenids after pupation 

 had been completed." 



The misleading resemblance between mimetic butter- 

 plies AND their models. — Prof. PouLTON exhibited examples 

 from a small general collection of butterflies bequeathed, with 

 the great British J. C. Dale Collection, to the Hope Department 

 by Mr. C. W. Dale, and received in 1906. The South American 

 Papilioninae were classified by pattern, as in all except the
