27 ; HesperiidsB, 62 — nearly all taken within three or four miles of 

 Port of Spain. The series of Heliconius telchinia and Tithorea viegara 

 var. jiavescens were particularly fine, showing the yellow colouration 

 only found in Trinidad and upon the coast of Venezuela immediately 

 opposite. A long series of Papiiio xeuxis and P. alyattus, many of them 

 bred from the same parent, female, show that these two are really 

 identical species. The number of Erycinidfe in Trinidad compared 

 with the poverty of the same family in other West Indian islands alone 

 indicates the different origin of its fauna, and suggests afiinity with the 

 mainland of Venezuela, which at the nearest point is but seven miles 

 distant. — Dr. Chapman exhibited specimens of Parnassius apollo taken 

 last July in Castile and Aragon (Spain), as well as a number of speci- 

 mens of both P. apollo and P. delins, chiefly Swisa and French, taken 

 by himself, Mr. Tutt, Mr. A. H. Jones (at Digne), and Mr. Rowland 

 Brown (at Susa, North Italy), for comparison with the Spanish speci- 

 mens and to illustrate the extent to which the races of these species 

 approached each other in Western Europe. The Spanish specimens 

 differed from most of the others in their great size, the males reaching 

 3f in. in expanse, and the females 3| in. Both males and females 

 seemed to be exceedingly close to the Asiatic form of apollo, called 

 hesebolus, in general facies. The males placed between ordinary Swiss 

 apollo and delim obviously incline much more to the latter than the 

 former in general tone of colour and intensity of markings. The 

 females were very large, and varied to forms with much increased red 

 ocelli. The best character whereby to distinguish apollo and delim is 

 certainly the black ringed anteunfe, which are also usually proportionally 

 shorter. The denser creamier colouring is also very characteristic, yet 

 this would make the Aragon specimen deltas. The pouch of the female 

 appears to be identical in both species. The male appendages seem to 

 have no ascertained structural difference beyond one in size, those of 

 apollo being larger and apparently more solid. In the Spanish apollo 

 this is markedly so, the differences, however, less proportionately than 

 may be observed in Erebia athiops, of which the appendages of Conti- 

 nental specimens are so much larger than those of British examples. — 

 Mr. G. C. Bignell sent for discussion a specimen of Sphecophaga 

 vesparuiii, Curt., and the cocoon from which it had been bred. Mr. 

 Donisthorpe expressed his opinion that the host was a ground wasp. — 

 Mr. Gilbert J. Arrow communicated a paper upon "The Genus Hyliota, 

 with descriptions of new forms, and a list of described species" ; and 

 Mr. W. L. Distant, " Contributions to a knowledge of the Rhynchota." 

 November 20^/i.— Mr. G. H. Verrall, Vice-President, in the chair. — 

 Mr. James B. Casserley, 7, Gloucester Road, Finsbury Park, N., and 

 Mr. M. Lawson Thompson, 35, Leven Street, Saltburn-by-the-Sea, 

 were elected Fellows of the Society. — Mr. A. H. Jones exhibited 

 various Lepidoptera from the Cevennes, including a series of Lycmia 

 dolus var. vittata, L. damon, L. meleager, Melanargia iapygia var. clean the, 

 and M. galatea ab. leucomelas ; also a dark form of Thais cerisyi bred 

 from a pupa received from Armenia. He also exhibited a specimen of 

 Vanessa antiopa taken this year at Eltham, and two specimens of 

 Cerastes erythrocephala bred from ova laid by parent moth captured at 

 sallows near Canterbury. — Mr. H. Rowland Brown exhibited a re-
