species of Cetoniidce, recently received from Central Africa, 

 and described by him in the February number of ' The 

 Entomologist'; also some varieties of N. polychrous, Thorns., 

 from the Zanzibar district. 



Dr. N. Manders exhibited a number of Lepidoptera collected 

 by himself in the Shan States, Upper Burmah ; also a col- 

 lection of Lepidoptera made by Captain Eaikes in Karenni. 



Mr. M'Lachlan exhibited over 400 specimens of Neuroptera, 

 being a portion of the collection formed in Japan by Mr. 

 H. J. S. Pryer. They represented nearly all groups (excepting 

 Odonata, now in the hands of Baron De Selys). Some of the 

 AscalaphidcB, FanorpideB, and especially Trichoptera, were of 

 great beauty ; notably amongst the latter was the curious 

 moth-like genus Perissoneura, M'Lacli. 



Dr. Sharp exhibited the peculiar cocoons of an Indian moth, 

 Rhodia newara, Moore ; these were the cocoons possessing a 

 drain at the bottom in order to allow water to escape, already 

 described in the ' Proceedings of the Zoological Society ' for 

 1888, p. 120, where, however, their great resemblance to the 

 pods of a plant had not been alluded to. 



Mr. Enock exhibited, and made remarks on, specimens of 

 Cecidomyia destructor, bred from American wheat. 



Mr. W. Warren exhibited a bred specimen of Retinia posti- 

 cana, Zett., from Newmarket ; also specimens of Eupithecia 

 jasioneata and Gelechia confinis, bred by Mr. Gardner, of 

 Hartlepool. 



Mr. C. 0. Waterhouse exhibited and explained a number of 

 diagrams illustrative of the external characters of the eyes of 

 insects. He observed that the simplest form of primary eye 

 is that of an Eciton ; the simplest form of compound eye 

 yet known is that of a Brazilian Lathridius with seven 

 unequal-sized facets ; between that and the eye of Spliinx 

 convolvidi (in which there are 27,000 facets), probably every 

 number may be met with. In several handbooks 34,000 

 facets are given as occurring in a Fapilio, but this is 

 an error ; this number refers to the two eyes, each having 

 17,000. The eyes are subject to various interruptions, the 

 most common being by an encroachment of the ocular 

 canthus, which in some cases completely divides the eye.
