Dr. Sharp exhibited specimens of the pupte of Microjjteri/x 

 (probably scmijiurpurdla) and drawings to illustrate their 

 structure. The pupte were sent to him by Dr. Chapman, 

 who had described their peculiarities in the Transactions of 

 the Society in 1893. Dr. Sharp considered the pupa to be 

 that of a Trichopterous insect ; most of its structures were 

 those of Trichoptera, and the account given by Dr. Chapman 

 of its emergence showed that this was essentially the same as 

 that of Trichoptera. He remarked that the imago of this 

 division of Mkropteripj had been already shown to approach 

 Trichoptera in several respects, and suggested that it should 

 be treated as a group of Trichoptera whose larva? are not 

 aquatic in habits. If this course were not adopted he felt 

 clear that Trichoptera could not be maintained distinct as 

 an order from Lepidoptera. He remarked on the peculiar 

 projection from the head of the pupa of Mieroptcnix, and 

 suggested that it might be comparable with the head-vesicle 

 of the nymph, or primary pupa, of Lepidoptera. He also 

 called attention to the importance, for a classification of 

 Lepidoptera, of obtaining a full knoAvledge of the structure 

 and life-history of Eriocephala calthella. Mr. McLachlau said 

 that so long ago as 1865 he had suggested the close affinity 

 of Micropteryjo to the Trichoptera ; the opinion then formed 

 had since been much strengthened, but he was not disposed 

 to admit co-ordinal relationship. Mr. Hampson, Mr. Barrett, 

 and Mr. Blandford also took part in the discussion which 

 ensued, 



Mr. McLachlan exhibited a singular instance of monstrosity 

 in a Dragon-fly. The insect was a male of Hetcsrina occisa, 

 Hag., from Venezuela. On the left side were three wings, 

 two mesothoracic and the other metathoracic ; on the right 

 side only one wing, the metathoracic. The supplementary 

 wing on the left side was inserted almost immediately 

 beneath the ordinary wing ; it was normal in form and 

 neuration, but the red pigment at the base (fully developed in 

 all the other wings) was not evident, the wing in this respect 

 being similar to those of highly immature examples of the 

 same species. 



Mr. E. E. Green exhibited a larva of an Homopterous
