Dr. Chapman exhibited the young larva of Kriocephala 
allionella. The egg was very similar to that of L. calthella, 
which he had previously figured. The larva was also closely 
alike but the tubercular appendages were proportionately 
smaller, The ova were from moths taken near Cannes. He 
also exhibited the skin of a female imago of //eterogyna penella, 
to show the muscles, which were well developed on a larval 
type in both the abdominal and thoracic regions. 
Mr. Jacoby exhibited a fine example of the large Hepialid, 
Leto venus, from Plettenberg Bay, 8. Africa. The President 
said that the insect afforded an interesting case of localised 
distribution, being confined to an area of about fifty by 
fourteen miles, whereas the larva fed in the wood of Virgilia 
capensis, @ common and widely-distributed leguminous tree. 
The insect was very conspicuous and could not have been 
overlooked in other localities. 
Mr. Burr showed a pair of gynandromorphous earwigs, 
Chelisoches morio, Fabr., from Java, with ordinary males and 
females for comparison. In both specimens the right branch 
of the forceps was of the male, and the left branch of the 
female form. De Bormans had recorded a similar case in 
Labidura pugnax, Kirb., from Burmah (Ann. Mus. Civ. Gen. 
(2), xiv., p. 877), in which also the right branch was male 
and the left female. In the National Collection there was a 
Chelisoches morio, in which the left branch was male and 
the right female. According to Brunner this phenomenon 
was not uncommon in the Forficulariide, but the speaker had 
heard of no other cases. 
The Hon. Walter Rothschild exhibited a series of speci- 
mens of Hudemonia brachyura, Drury, and FE. argiphontes, 
Kirby, to show the differences between these two West 
African Saturniid moths. The distinctness of the latter 
species had been doubted, as until recently it was only
