so apparently more solid. In the Spanish Apollo this is markedly so, the differences 

 are however being less proportionately than may be observed in Erebia cethiops, of 

 which the appendages of Continental specimens are so much larger than those of 

 British examples. Mr. G. C. Bignell sent for exhibition a specimen of Sphecophaga 

 vesparum, Curt., and the cocoon from whicli it had been bred. Mr. Donistliorpe 

 expressed his opinion that the host was a Ground Wasp. Mr. Gilbert J. Arrow 

 communicated a paper upon "The Genus Hgliota, with descriptions of new forms 

 and a list of described species ;" and Mr. W. L. Distant, " Contributions to a know- 

 ledge of the Rhgnchota." 



November 20th, 1901. — Mr. G. H. Vekkall, Vice-President, in the Chair. 



M. James B. Casserley, 7, Gloucester Boad, Finsbury Park, N. ; and Mr. M. 

 Lawson Thompson, 35, Leven Street, Saltburn-by-the-Sca ; were elected Fellows of 

 the Society. 



Mr. A. H. Jones exhibited various Lepidoptera from the Cevennes, including a 

 series of Lycana Dolus, var. vittata, L. Damon, L. meleager, Melanargia iapygia, 

 var. Cleanthe, and 31. Galatea, ab. leucomelas ; also a dark form of Thais verisyi 

 bred from a pupa received from Armenia ; also a specimen of Vanessa Antiopa taken 

 this year at Elthatn, and two specimens of Cerastis erythrocephala bred from ova 

 laid by parent moth captured at sallows near Canterbury. Mr. H. Rowland-Brown, 

 a remarkable var. of Melitcea didyma, taken at Chateau de la Caze, Tarn, in which 

 the black markings of the under wings were almost entirely absent, and a series of 

 Lyccena Dolus, var. vittata, from the Cevennes, with L. Admetus, var. Rippertii, 

 showing the remarkable affinity of the two species, which, however, were never 

 found on the same ground or in the same localities while collecting. Dr. Chapman, 

 butterflies taken by himself and Mr. G. C. Champion in the Sierra Albarracin, 

 Spain, last July ; he said, " The district traversed by Mr. Champion and myself 

 was practically the same as that described by Mrs. Nicholl in her paper in the 

 Transactions for 1897, and not many new butterflies were added to the list therein. Z. 

 quercus was taken at Tragacete, but this is in Castile, not in Aragon. Atigiades sylva- 

 nus was taken both at Albarracin and Tragacete. Adopcea Avtceon was met with at 

 Cuenca (Castile). Adopcea linea seemed to be more abundant than lineola at all 

 stations. L. hylas and its variety, nivescens, were found on the same ground. The 

 common form of L. Corydon seemed to be corydonius, or near that variety. The 

 very large pale form hispana was the commonest at Albarracin, where the corydo- 

 nius form was rare, and at Cuenca, and was not seen at Tragacete. Looking at these 

 and other dimorphic forms occurring here, one could not help questioning whether 

 Admetus might not be a dimorphic form of Damon. The former was often abund- 

 ant, the latter always rather scarce. The females, however, have constant differences, 

 and the general tone of colour and arrangement of spots on the under-sides seem 

 abundantly sufficient to satisfy one that they are definite species, though very closely 

 allied. L. Dolus seems to occupy precisely the relation to Damon that nivescens 

 does to hylas and that the vars. hispana and albicans do to Corydon. The male 

 appendages of the three, Damon, Dolus, and Admetus appear to be identical. We 

 observed nothing to account for or explain the use of the colouring of S. Uhagoni. 

 It resembles very much the female of Semele, which is abundant on the same 

 ground. But the habits of flight of the two are very different, and we never in
