( XXXV ) 



following species, amongst others, were represented, viz. : — 

 Crymodes exulis, Triphcena pronuba, Noctua conflua, Pliisia 

 gamma, Larentia casiata, Eupithecia scoriata, Melanij)pe sociata, 

 Coremia munitata, Phycis fusca, and Cramhus pascuellus. 



The Rev. Dr. Walker also exhibited a number of Lepi- 

 doptera, Diptera, and Hymenoptera, recently collected by 

 himself in Iceland. The collection included the following, 

 viz. : — Crymodes exulis, Noctua conjiua, Larentia catsiata, Co- 

 remia munitata, Culex pipiens, Scatophaga stercoraria, Calliphora 

 erythrocephala, Helophilus grcenlandica, Bombiis terrestris, &c. 



Mr. W. White exhibited, on behalf of Mr. G. C. Griffiths, 

 a specimen of NejjJironia hippia, Fab., var. g(£a, Feld., having 

 the external characters of the male on the right side, and 

 of the female on the left side, and which he believed to be 

 hermaphrodite. He said it was exactly similar to the types 

 oi gmi figured by Distant ('Rhopalocera Malayana'), with the 

 exception that the marginal spots on the upper wing side are 

 much developed and larger. This however, might be a 

 transference of character from the female influence, as 

 a result of hermaphroditism. An enlarged sketch of the 

 genitalia (which were fortunately pressed out) exhibited what 

 he supposed to be the ovipositor, and a single clasping organ 

 on the male side. He further pointed out that the species 

 was an interesting one also on account of its mimicking two 

 species of Danais — agleoides and melaneus — equally. Mr. White 

 quoted Mr. Distant as considering gcea to be a variety of hippia, 

 and as distinct ixom. Valeria "by the character of the pale- 

 spotted outer margin of the anterior wings. Even treated as 

 a distinct variety, considerable variation is discovered amongst 

 the female examples, particularly as regards the amount of 

 ochraceous markings on the abdominal area of the upper 

 surface of the posterior wings, and the depth of hue of the under 

 surface of the same wings, which are either infuscated, as in the 

 specimen figured, or almost greyish, as in other examples. 

 The fuscous margin containing the series of pale spots is, 

 however, always present" (p. 321 'Rhopalocera Malayana'). 



A discussion on hermaphroditism ensued, in which Mr. 

 Distant, who exhibited type examples of the species, Mr. 

 Elwes, Mr. M'Lachlan, and Mr. Baker took part.
