developed, but extremely small, and the left bind wing slightly more 

 elongated than the right hind wing. Mr. C. 0. Waterhouse exhibited 

 a tube which formed the entrance to a nest of a Triffona, sent from 

 Singapore by Mr. H. N. Ridley. It was about fifteen inches in length, 

 of a resinous substance, but more waxy towards the end, which was 

 spoon-shaped. He also exhibited a portion of the resinous mass formed 

 within the trees by these bees, and stated that one of these masses sent 

 from Penang by Mr. Ridley weighed fifteen pounds. The true nest of 

 the Tricjona consists of an irregular mass of cells filled with honey, quite 

 distinct from the resinous formation. A paper was communicated by 

 Mr. W. H. Ashmead, Assistant-Curator of the United States Natural 

 History Museum, on " The Aculeate Hymenoptera of the Islands of 

 St. Vincent and Grenada, with additions to the Parasitic Hymenoptera, 

 and a List of the described Hymenoptera of the West Indies." 



April Uh. — Mr. G. H. Verrall, President, in the chair. Mr. J. W. 

 Carter, of 25, Glenholme Road, Manningham, Bradford ; Mr. L. L. 

 Feltham, of Johannesburg, South Africa; and Mr. H. Fortescue Fryer, 

 of the Priory, Chatteris, Cambs, were elected Fellows of the Society. 

 Mr. M. Jacoby exhibited specimens of the genus Sagra from Eastern 

 Asia. Mr. M. Burr exhibited three species of Pseudophyllidae, two new 

 species of CapnojJtera (females), and C. quadrimaculata, Westw. (female), 

 collected in the Siamese Malay States by Mr. M. Annandale. One of 

 the specimens illustrated the peculiar methods of offence adopted by 

 the insect when alarmed. Between the head and the pronotum a 

 scarlet hood was visible, the inflation of which bladder-like organ 

 always indicates fear or anger. The other specimens showed the 

 natural position of the head and pronotum. Mr. H. J. Elwes com- 

 municated a paper on "Bulgarian Lepidoptera," and made some 

 remarks on the more notable species which he had taken in the 

 Balkan Peninsula during the months of June and July, 1899. The 

 number of species of Rhopalocera captured was 120, which, with a 

 further twenty recorded by Haberhauer and Lederer, brings up the 

 total to 140. The mountains visited were an extension of the 

 Rhodope range, where the climate was particularly rainy, a great 

 number of ferns flourishing everywhere, in contrast to the drier 

 Balkans, where the number of species of Rhopalocera is not less 

 than 200. Some interesting forms, but no new species, were en- 

 countered. A variety of Colias myrmidone occurred much larger 

 and brighter than the Austrian, and more nearly agreeing witii 

 the Ural form ; and whereas in Austria the white aberration is 

 exceedingly rare, in this locality it predominated. Meanwhile the 

 orange forms clearly resembled C. heUlreichi. The form of Cceno- 

 nympha daviis met with showed an affinity with the Asiatic and not 

 the European form, being almost precisely similar to specimens 

 taken in the mountains of Armenia by Haberhauer. The form of 

 Argynnis pales was intermediate between that found in Greece and 

 the Central European Alps, while a form of Erebia var. gorgone was 

 taken similar to that in the Pyrenees — a curious instance of interrupted 

 distribution. — C. J. Gahan & H. Rowland Bkown, Hon. 8ecs.
