laid by a female captured in April, 1898, at Digne. The first portion, twenty-one 

 males, emerged in 1899, the second portion, two males and seven females, emerged 

 in 1900, and two piipfle remained over, but had since died. Mr. Blenkarn reported 

 that he had taken the rare Ischnura pumilio in Abbot's Wood. Dr. Chapman, 

 specimens of Cnethocampa pityocampa, pi-epared to show the frontal apparatus for 

 forcing an exit from the tough cocoon, which process he explained was also assisted 

 by the special development of the first pair of imaginal legs. — Hy. J. Turner, 

 Hon. Secretary. 



Entomological Society of London : October 3rd, 1900. — Mr. Gr. H. 

 Veeeall, President, in the Chair. 



Mr. E. A. C. Studd, Oxton, Exeter ; Mr. H. Maxwell Lefroy, B.A., Economic 

 Entomologist to the Imperial Agricultural Department for the West Indies, Bar- 

 badoes ; Mr. W. F. Urwick, 34., G-reat Tower Street, London, E.G. ; were elected 

 Fellows of the Society. 



Mr. Gr. C. Champion exhibited specimens of Troy op h Ice us anylicanus, Sharp, 

 found by Mr. Keys at Plymouth ; Pachyta sexmaculata, L., found by Col. Yerbury 

 at Nethy Bridge, and Anchomenus quadripunctatus, De Greer, found by himself at 

 Woking. Mr. M. Jacoby, an ichneumon, Rhyssa persuasoria, taken by him at 

 Blandford, parasitic on Sirex, and Col. Yerbury said that he had met with the same 

 species iir some numbers in Scotland. One female observed in the act of oviposition 

 had thrust her ovipositor through an inch of fir trunk. Col. Yerbury, (1) a rare 

 sawfly, Xyphidria camelus, taken in Scotland this year at Nethy Bridge. The 

 species is mentioned in the old books as extinct in the United Kingdom, and Mr. 

 Waterhouse said there were no modern specimens in the South Kensington Museum 

 collection ; (2) rare Diptera from Scotland, including (a) Laphria Jlava, two males 

 from Nethy Bridge ; (J) Chamcesyophus scceoides, new to Britain, from the Mound, 

 Sutherland, where it was common on UmhellifercB, one female also being taken on 

 the path up Cairngorm ; (c) Microdon devius; (d) Chilosia chrysocoma at mountain- 

 ash blossom, Nethy Bridge ; and (e) Stomphastica Jlava, two males from Golspie, 

 September, 1900. Mr. H. K. Donisthorpe, (1) a Drusilla canaliculata, with the 

 dead body of a Myrmica in its mouth, captured at Chiddingfold on July 17th ; (2) 

 Myrmedonia collaris and its larva taken in Wicken Fen, with M. Icsvinodis, in 

 August, 1900. The Rev. F. D. Morice, a remarkable hermaphrodite of the bee 

 Podalirius (= Anthophora) retusus, in which the male characters were confined to 

 the left side of the head and genitalia, the right side of the thorax and the abdo- 

 minal segments. The antennae and hind (pollinigerous) legs were those of a female, 

 and the genitalia half of each sex. Dr. (/hapman, beetles of the genus Orina, some 

 of them alive, and remarked on the fact tiiat while some were viviparous othei-s were 

 oviparous, in some cases of the former the larvse being developed in the ovarian 

 tubes. Mr. H. J. Elwes, a collection of Lepidoptera from Greece, taken this season 

 in conjunction with Miss Fountaine, in the Morea, and in the Parnassus region. 

 He remarked that the country about Athens was iimch dried up, and therefore the 

 Lepidopterous fauna was poor. On the south side of the Gulf of Corinth, however, 

 the PieridcB were well represented, and out of eight European species seven were 

 taken in three weeks. The spring and summer broods of Pieris Krueperi this year 

 were flying together — an unusual occurrence, possibly due to the rainy spring.
