cells were left open on both sides, but when the cell was complete below only 

 one surface of the insect could be examined. 



Mr. Billups exhibited Meteorus luridus (Ruthe), a species of Ichneumonidse 

 new to Britain, obtained by Mr. Bignell. 



Mr. W. White, in exhibiting cocoons of Cerura vinula t called attention to 

 the vexed question as to how the perfect insect escapes from these solid struc- 

 tures. He was inclined to think that formic acid, secreted by the insect, was 

 a probable factor in the operation. The question as to the mode of escape 

 from these cocoons of the parastic Ichneumonidse and Diptera was also raised ; 

 and the President, Baron Osten-Sacken, Mr. Waterhouss, and Prof. Meldola 

 made remarks on the subject. 



Mr. Elisha exhibited living larvse of Geometra smaragdaria from the Essex 

 marshes. He also exhibited the singular pupae of A, Bennettii. 



Mr. Howard Vaughan exhibited a series of several hundred bred specimens 

 of Peronea hastiana, showing the innumerable varieties of the species. He 

 also exhibited, on behalf of Mr. Sidney Webb, of Dover, an interesting series 

 of Cidaria suffumata, with especial regard to the progeny of particular females, 

 the parent and the produce of the eggs laid by her being carefully separated. 

 Mr. Vaughan also read notes on the subject communicated by Mr. Webb ; 

 and Mr. Jenner Weir, Mr. Waterhouse, Mr. Distant, Dr. Sharp, and Mr. 

 Stainton took part in the discussion that ensued. 



Mr. A, G. Butler communicated a paper on " New Genera and Species of 

 Lepidoptera-Heterocera from the Australian Region " in which 21 new genera 

 and 103 new species were described. 



Mr. J. S. Baly communicated a paper on " Uncharacterized Species of 

 Diabrotica" — H. Goss, Secretary. 



HAGGERSTON ENTOMOLOGICAL SOCIETY. 



At the Meeting of May 27th, Mr. J. A. Clark exhibited a very beautiful 

 series of Xylocampa lithoriza bred from ovss, and several other exhibits were 

 placed upon the table. Reporis from various members were unanimous in 

 stating Epping Eorest to be in a very swampy state owing to the heavy rains, 

 and lepidoptera were scarce, especially Diurni ; a few half torpid Alveolus and 

 Tapes on the rushes being almost the only species observed. 



The next Meeting was the 28th, Annual Meeting, and was chiefly occupied 

 with the Secretary's Report, and with the Election of Officers, all the gentle- 

 men previously serving being re-elected. The President exhibited specimens 

 of A. prunaria, bred the same day, and stated that for two years previously 

 he had been breeding the pure orange or lemon forms only, but wishing to 

 obtain some banded forms, he visited Epping Forest in June 1885, and
