in which "every single pupa was parasitized in this way." 

 Prof. Poulton pointed out the bearing of these and Mr. 

 Guy Marshall's earlier observations on the extraordinary 

 assumption of the late Erich Haase, that the specially pro- 

 tected species of Lepidoptera are immune from the attacks of 

 parasites. 



Some Ant-tended Lycaenid Larvae observed by Mr. \Y. A. 

 Lamhurn in the Lagos District. — Prof. Poulton exhibited 

 material illustrating the following records received in letters 

 from Mr. Lam born —

Marc/, 3/--/, 1911. 

 " The food-plant, which bears a fruit much like a little fig, 

 grows here and there in the primitive forest round Oni camp. 

 The larva of Euehromia lethe, V., also feeds upon it, as well as 

 that of a Sphingid moth. The larvae are green with white 

 tubercles and are not very conspicuous on the food-plant, 

 though found in all positions on it, on both sides of the leaves 

 and frequently on growing buds at the end of stems. They 

 pupate anywhere; frequently on the upper ride of a leaf. It 



is vi'iy common to find the larvae attended by ants of various 

 kinds, which run all over them, and the larvae do not notice 

 them in the least even when feeding. The pupae also seem to

 " 1 lie larvae of all these have been found all round ahout Oni 

 camp ; for the food-plant grows abundantly in the clearing. 

 The larvae are found sometimes on the upper side of a leaf 

 even during the heat of the day, and they are leaf-green in 

 colour. Both larvae and pupae attract ants to a remarkable 

 degree. I have learnt that it" ants are running about on the 

 food-plant without flowers, larvae are almost certainly on it, 

 and if there are no ants I do not trouble to make an ex- 

 haustive search. My first half-dozen larvae were placed in 

 a box covered with fine muslin. On the following morning I
