214 THE ENTOMOLOGIST. 



Ornithoptera from Cochin. — Mr. Dunning veraavked that 

 the Ornithoptera bred by Mr. Sealy from larvae 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 larvae were still alive and healthy. 



Parasitic Coleoptera, dc. — The President also exhibited 

 an example of the minute Hylechthrus Rubi, one of the 

 Stylopidae, parasitic upon Prosopis rubicola, recently obtained 

 from briars imported from Epirus, and remarked upon a 

 method of expanding the wings of Stylopidae. 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 Crabronidae) 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. praeusta) from those of Anthidium contractum, 

 which latter had also produced two species of Chalcididae 

 (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
