jar of moss, but succumbed to the heat of the tropics. He also 

 showed two slides of microscopical preparations from a third 

 larva, including the mouth-parts, antennae and armature of 

 the cuticle. Dr. Tillyard also exhibited a gigantic undescribed 

 species of Heterojapyx from Sydney, specimens of which have 

 been found more than two inches long when alive. A dis- 

 section of this insect revealed the interesting fact that vestiges 

 of the Malpighian tubules are present in the form of a circlet 

 of six small evaginations of the anterior end of the hind-gut. 

 A further exhibit was a set of tubes showing the eggs, larvae, 

 pupae and imagines of the remarkable Australian Moth-lace - 

 wing, ItJione fusca. The eggs are laid in the sand and hatch 

 out into little white melolonthoid-like grubs, which burrow 

 downward and attack the larvae of Scarabaeidae. The 

 mouth-parts are very small, but of the true planipennian 

 sucking type; the head is reduced, eyes absent, and the fore- 

 legs formed for burrowing. The larva gives out a delightful 

 scent of lemon essence. The pupa is enclosed in a cylindrical 

 cocoon with rounded ends, formed of a white papery substance, 

 like that made by some Hymenoptera. The imago superficially 

 resembles a Hepialid moth. It flies only at sunset, the males 

 assembling in dozens round the females on tree-trunks.

 Mr. Talbot, on behalf of Mr. J. J. Joicey, exhibited the 

 following Gynandromorphs : — 



Papilio castor, Westw. — The left side is female. The right 

 side is a mixture of both sexes. 



Teracolus pleione, Klug. — A specimen taken at Aden, from

Delias descombesi leucacaniha, Fruh. — A specimen from 

 Sikkim from the collection of H. J. Elwes. Left side male,

 of Staudinger and Bang-Haas. One specimen with the right 

 side male, and left side female, with left hind-wing partly 

 male. Second specimen with right side male, left side female 

 with apparently an admixture of male elements.
