this species there is no considerable development of the opercula. Most of 
the Cicadide were peculiar in having different times of the day when they 
stridulated, and Mr. Distant recommended this practically unworked field 
for observation to entomologists abroad. 
Mr. T. R. Billups exhibited a female specimen of Dufourea vulgaris, 
Schk., captured on a bloom of ragwort on the banks of the Basingstoke Canal 
at Woking, August 1st, 1881. This was the first female taken in Britain. © 
Sir Sidney S. Saunders said he captured a male near Chewton, Hamp- 
shire, in August, 1879. He believed this genus was rare on the Continent, 
as Lepeletier de St. Fargeau had never met with specimens himself, but 
described a male and female from Latreille’s collection. 
Sir Sidney S. Saunders exhibited a species of Scleroderma received from 
M. Ed. André, of Beaune, who states that it was sent to him by an 
entomologist of Lyons, “ayant vécu a l'état de larve dans un pin maritime 
et au dépens d’une larve de Coléoptére.”” It coimcides with the S. domestica 
described from Berlin specimens in Prof. Westwood’s Monograph of the 
genus in the second volume of our ‘Transactions,’ the scape of the 
antenne, however, not being obscure at the base. 
Sir Sidney Saunders also exhibited specimens of two dipterous insects, 
Oscinis frontella, Fall., and Drosophila fenestrarum, Fall.; the former reared 
from wild figs forwarded by Mr. Frank Calvert, of the Dardanelles ; the 
latter from the Egyptian sycamore figs. In both instances the parent flies 
appear to have entered these figs after the Cynipida, reared therein on the 
seed-germs, had escaped through a large aperture which they make by 
gnawing around the crown until this falls in. The slender white worm- 
like larvee of the Oscinis were wriggling about amid the pulp of the fig, 
together with many of the fragments of the former occupants, chiefly males 
which never quit the fig; anda large number of the Oscinis pupe —some 
of these obtained from their larve placed apart for identification—were 
found attached to the paper wherein the figs were enveloped, the flies 
emerging about three weeks later in September. 
These figs were sent with the object of possibly obtaining from that 
locality specimeus of the Cynips Psenes of Linneeus, found by Hasselquist 
near Smyrna in the figs of the “ Ficus Carice orientalis,” as described in 
his ‘Iter Palestinum,’ edited by Linneus in 1757, and therein adverted 
to under the names of C. Ficus and C. Carica, found (April 6th) in the 
same fig (in eadem cum altero Ficu), but the latter supposed to differ 
from the former in species or in sex, while minutely defining the oviduct 
of each; both having been united by Linnzus the following year, in 
his tenth edition of the ‘Systema Nature,’ under the denomination of 
Cynips Psenes. 
The types of C. Ficus exist in the Linnean Cabinet at Burlington 
House, but no one appears to have met with it since that period. This
