having been procured as well as workers, soldiers, winged 
individuals, and the immature forms. 
Mr. Haviland gave an account of the manner in which he 
examined the nests so as to find the royal couple, which he 
stated frequently required some hours of search. There is 
great variety in the habits of the Termitide, and Mr. 
Haviland observed that at least one species wanders at large 
after the manner of the Hymenopterous ants; this it does at 
night, and individuals of this species may be found returning 
in the morning to their nest, the workers carrying balls of 
food, and being escorted by soldiers, who, however, carry no 
food. Mr. Haviland further stated that one or two of the 
Singapore species made use of mushrooms, which were 
growing in chambers near their nests, after the manner 
described by Smeathman in the Philosophical Transactions 
of the Royal Society. He had examined the alimentary 
canal and found spores of these fungi therein. Mr. Haviland 
mentioned that in the case of a species which is at present 
committing great havoc in the Museum at Singapore, he had 
not been able to find the reproductive individuals. 
Colonel Swinhoe said that it was generally considered in 
India, that the fertile females were never found in human 
habitations, even when these were much infested by the Anis. 
Mr. H. Goss remarked that the fact that the different forms 
of social insects were produced by nutrition was apparently 
known to Virgil, who, he believed, referred to it, and to the 
subject of Parthenogenesis in Bees, in the ‘‘ Georgies,”’ 
Book iv. Mr. McLachlan, Colonel Swinhoe, Mr. Champion, 
Mr. Jenner Weir, and Dr. Sharp continued the discussion. 
Mr. O. E. Janson exhibited specimens of Dicranocephalus 
adamsi, Pascoe, from Sze-chuen, Western China, and D. 
dabryi, Auz., recently received from the neighbourhood of 
Moupin, 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 when 
describing them, and presented a remarkable difference, for 
whilst in dabryi this sex is similar to the male in colour and 
sculpture, in adamst it is entirely dull black, with the upper 
surface minutely and densely punctate,
