452 ANNUAL REPORT SMITHSONIAN INSTITUTION, 1925 



fore legs were not used for this purpose at all in the instance he 

 witnessed, and that the homoptcron was quite free. There were 

 plenty of ants on the branch, which was some 4 to 5 feet from the 

 ground, but they did not seem to disturb the butterflies. 



About January 20, 1910, the same native again brought in this 

 species of AUotinus, together with an homopteron, telling Mr. INIoul- 

 ton that he had watched them for a long time and that he was con- 

 vinced that the lycaenid in no way held the homopteron. On Feb- 

 ruary 2, 1910, he brought in another AUotunis (of a species near 

 nivalis) which he had found in similar attendance on the same spe- 

 cies of homopteron (also brought in). As before, he told him that 

 he watched them for some time to see if there was any restraint 

 imposed on the homopteron, but he was quite sure that it was free. 



About February 10, 1910, Mr. Moulton's Dyak Kigi brought him 

 an example of Allotinus horsfieldi which he had taken in attendance 

 on a " heteropterous larva." In the case of this last observation the 

 collector reported having noticed large numbers of this insect on the 

 tree in company with many ants, which latter appeared to be bother- 

 ing the lycsenid, although he stuck to his work in spite of the ants 

 until the collector's net removed him. In the previous observations, 

 except for the homopterons attended by the butterflies, none or but 

 few were seen on the same tree. 



Gerydino^ sp. indet.— In a letter to Prof. E. P. Poulton, Mr. J. C. 

 Moulton wrote : 



I watched some few months ago a group of ants, a Lyca^nid belonging to the 

 subfamily Gerydinix?, and Homoptera (identified by Distant as the Membracid 

 Ebhul vnrius Walker, previously only known from the unique Burmese 

 type). The Membracids were quite passive while ants vigorously massaged 

 them and imbibed the exuding liquid. The Gerydus rested within a foot of an 

 ant slowly stroking an Homopteron with his proboscis and I suppose at the 

 same time drawing up liquid. 



According to Professor Poulton the observation was made in the 

 neighborhood of Kuching in 1913. 



These observations by Colonel Barrow, the Dyak Rigi. and Mr. 

 J. C. Moulton must be considered in connection with Mr. Ivamboi-n's 

 notes on Megalopalpus^ the African representative of the oriental 

 Allotinus^ and Mr. Kershaw's on Gerydus chinensis. Feniseca tar- 

 quinius also seems to be quite immune from attack by ants. 



A NOXCARNIVOROUS BUTl'ERFLY FEEDING WITH IMPUNITY AMONG ANTS 



ON COCCID SECRETIONS 



Mr. Charles O. Farquharson gives an excellent accoimt of a but- 

 terfly of the genus Teratoneura feeding on the secretions of ant- 

 attended coccids and driving off the ants.
