214 THE ENTOMOLOGIST. 
Ornithoptera from Cochin—Mr. Dunning remarked that 
the Ornithoptera bred by Mr. Sealy from larve taken at 
Cochin, South India, and exhibited by him at a recent 
meeting, had been identified as O. Minos. 
Curculio attacked by a Fungus.—Mr. Bond exhibited two 
specimens of a Curculio, sent by Mr. Griffin from Nova 
Fribourgo, Brazil, which were attached to the same twig, and 
were both attacked by a fungus. Mr. Janson said that they 
belonged to the genus Hylopus, and were well known to be 
subject to such attacks. 
Osmia nesting in a Lock.—The President exhibited a lock, 
taken from a gate at Twickenham, entirely filled with the 
cells of a species of Osmia, which Mr. Smith said was most 
probably O. bicornis, of which he had known several instances 
in locks. The larve were still alive and healthy. 
Parasilic Coleoptera, &c.—The President also exhibited 
an example of the minute Hylechthrus Rubi, one of the 
Stylopide, parasitic upon Prosopis rubicola, recently obtained 
from briars imported from Epirus, and remarked upon a 
method of expanding the wings of Stylopide. In repose 
these wings were rolled up in an elongate form; but he found 
that by pressing them gently forward from below they 
suddenly became erect, and then easily retained an expanded 
position. He further exhibited males and females of Spilo- 
mena troglodytes (one of the Crabronide) reared from 
bramble-stems found at Shere, in Surrey; also a series of 
Halictus nitidiusculus, stylopized, and recommended ento- 
mologists going to the south coast in August to search for 
stylopized Halicti, especially on thistles. Finally, he remarked 
on the parasites of Osmia and Anthidium ; and exhibited two 
specimens of the Coleopterous genus Zonitis (Z. mutica and 
Z. bifasciata) reared from the cells of Osmia tridentata, and 
a third (Z. preusta) from those of Anthidium contractum, 
which latter had also produced two species of Chalcidide 
(Leucospis dorsigera and Eurytoma rubicola). He enume- 
rated eleven species of Insect as attacking the same Osmia in 
various stages, of which he had himself reared six, including 
the two Zonites aforesaid, the other four being Cryptus 
bimaculatus, Melitobia Audouini, Halticella Osmicida, and 
Chrysis indigotea; some of which had been recorded by 
Dufour and Perris, together with Stelis minuta and two
