specimen. Fig. 1 is, however, a hybernating form, assumed by a 

 Laggard at the 8th skin. Fig. 2 is a Laggard in 4th skin ; compare 

 with Normal in 4th skin (Plate I, fig. 8). Fig. 3 is a Laggard 

 hybernating in 7th skin. 



Fig. 5 is a hybernating form that is rather rare, and is remarkable 

 for its large size and cam-like plumage ; several of these occurred in 

 later broods ; the one figured Avas in its 6th skin, and was descended 

 from the large red hybernating larvae already referred to, as the only 

 definite variety of hybernation that occurred in the first brood. 



Figs. 6 and 7 represent the anal armature of coia pupa ; beyond 

 the opportunity afforded for having the drawings made, they have no 

 connection with the subject of this paper, but they interested me as 

 having, more than any other pupa that I have met with, certain features 

 very similar to those of Acronycta pupte. The two definite dorsal 

 spines and the numerous ventral set, being of the same pattern as pre- 

 vails amongst the Cuspidiae, whilst the texture of the pupa reminds one 

 a good deal of Viminia. These facts make one suspect that the 

 resemblance of the larvae of Viminia to those of Arctia may indicate 

 relationship, extending as it does to an identity of the lateral strii^e in 

 menyanthidis and rumicis with that found in some varieties of young 

 caid larvfe.

Three meetings of The Entomological Society of London have 

 been held since our last note. — On March 14th, Dr. D. Sharp exhibited 

 a collection of White Ants (Termites), comprising about a dozen species, 

 which had been taken by Mr. G. D. Haviland, in Singapore ; he stated 

 that Mr. Haviland had found in one nest eleven neoteinic queens, — 

 that is, individuals having in some respects the appearance of queens, 

 while in other respects they were still immature ; these neoteinic 

 queens were accomj^anied by kings in a corresj^onding condition. Dr. 

 Sharp alluded to the opinion expressed by Mr. Herbert Spencer, in his 

 recent discussion with Prof. Weissman, that the different forms of social 

 insects were produced by nutrition, and said that the observations made 

 by Prof. Grassi, showed the correctness of this view. Mr. Haviland 

 stated that two of the species exhibited, certainly grow fungus for their 

 use, as described by Mr. Smeathman many years ago, in the Philo- 

 sophical Transactions. Mr. Goss remarked that Virgil (Gcorgics, Book 

 iv.), referred to the fact that the different forms of social insects were 

 produced by nutrition, and also to parthenogenesis in Bees. Mr. 

 0. E. Janson exibited specimens of Dicranocephalus adamsi, Pascoe, from 

 Sze-chuen, Western China, and D. dahryi, Auz., recently received from 

 the neighbourhood of Meupin, in the same district ; he observed that, 

 although the latter had been quoted by Lucas, Bates, and others, as a 

 synonym of adamsi, the two species were perfectly distinct ; the females 

 of both were unknown to the authors, and presented a remarkable 

 difference, for whilst in dahryi this sex is similar to the male in colour 

 and sculpture, in adamsi it is entirely dull black, with the upi)er surface 

 minutely and densely punctate. Mr. C. 0. Waterhouse exhibited, for 

 Mr. E. A. Waterhouse, a specimen of Colias ednsa, closely resembling 

 C. erate (a Continental species), which was taken on Wimbledon Common,
