prove that they were not homologous with the entire cerci ; 
perhaps the internal structure of the latter was retracted by 
a histolytic process before amputation. In Forficula he had 
found evident traces of meristic division in the forceps of 
embryos which were nearly on the point of hatching. 
Dr. CHapman read a paper entitled “Some remarks on 
Heterogyna penella,” giving a full account of its life-history. 
The female was destitute of all appendages whatever, and 
only left the pupal case for pairing, returning within it about 
ten minutes later. It possessed an organic connexion with 
the pupal case in the situation of the legs. The larve were 
hatched within the case and devoured the remains of the 
mother. The pupa of the female was quite peculiar and 
specialized in structure, and utterly unlike that of the male. 
The larva-like character of the female imago he did not 
regard as ancestral. On anatomical characters he assigned 
to the insect a place near the Zygenide. 
Sir Grorce F. Hampson pointed out that Herrich-Schatter 
had suggested on other grounds that Heterogyna was probably 
a link between the Psychide and Zygenide.

the Society. 
Exhibitions. 
On behalf of Mr. Greenshields, Mr. Jacosy exhibited 
specimens of the longicorn beetle, Micropsalis durnfordi, 
Burm., from Patagonia. Mr. Greenshields, who was present, 
stated that this species, remarkable for the great development 
of the palpi, was originally taken by Darwin; his own ex- 
amples were taken hiding in thorny bushes, locally known 
as ‘Calefatas,” in a dry water-course. It was necessary to 
beat these bushes before the insects would come out. They
