slender-bodied Asilid of unusual colouring, which, resting on 

 a grass stem, looked rather like a very small Agrionine." 

 The resemblance, which was sufficiently strong in the set 

 specimen, was probably closer in the attitude of rest. Dr. 

 G. A. K. Marshall 'had kindly helped in tracking the species, 

 which was evidently near L. lugens, Lw. 



Mr. C. 0. Farquharson's investigations into the life- 

 histories OP S. Nigerian Lycaenidae. — Prof. Poulton 

 said that for some years Mr. Farquharson had corresponded 

 with him on the above subject, and he hoped, as soon as a 

 few points had been cleared up, to bring forward a detailed 

 account of the discoveries. In the meantime the results 

 were so interesting and important that it was desirable to 

 make a brief announcement of Mr. Farquharson's main 

 conclusions. 



(1) The Liptenine Lycaenidae of the genera Hewitsonia, 

 Iridopsis, Teratoneura and the genus to which " Epitola " 

 honorius, F., belongs, possess hairy Lymantriid-like larvae 

 which feed on the delicate filmy lichen encrusting the bark 

 of certain forest trees infested by Cremastogaster ants. The 

 larvae are not molested even when walking in the regular 

 ant-track. 



(2) Lachnocnema larvae not only feed on Jassidae, as shown 

 by Mr. W. A. Lamborn (Trans. Ent. Soc, 1914, pp. 470, 471), 

 but also on the secretions of immature ant-tended Membracids, 

 as well as on insect food. 



(3) Two species of Argiolaus feed, as larvae, on the flowers 

 of a parasitic ant-infested Loranthus. The Rev. K. St. Aubyn 

 Rogers has also recently suggested that a parasitic creeper, 

 probably a Loranthus, is the food-plant of a fine species of 

 Argiolaus in late German East Africa. Pupae were on several 

 occasions found attached to the plant. 



(4) Pilodeudorix camerona, Plotz, P. digllus, Hew., and 

 Lycaenesthes musagefes, Holl. (kindly determined by Mr. G. 

 T. Bethune-Baker) feed, as larvae, on the ant-infested flowers 

 of a species of Pterocarpus. 



(5) Quite recently, on Sept. 10 last, the pupae of Cato- 

 chrysops parsimon, F., were found in large numbers, together 

 with mature larvae, in the subterranean nest of Camponolus
