markable var. of Melitasa didyma, taken at Chateau de la Caze, Tarn, in 

 which the black markings of the lower under-side wings were almost 

 entirely absent ; and a series of Lycana dolus var. vittata from the 

 Cevennes, with L. admetus var. rippertii, from Digne, showing the re- 

 markable affinity of the two species, which, however, were never found on 

 the same ground or in the same localities while collecting. — Dr. Chapman 

 exhibited 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 the ' Transactions ' for 1897, and not many new 

 butterflies were added to Mrs. Nicholl's list. Z. quercus was taken at 

 Tragacete, but this is in Castile, not in Aragon. Augiades sylvanus was 

 taken both at Albarracin and Tragacete. Adojjcea actceon was met with 

 at Cuenca (Castile), while Adopcta linea seemed to be more abundant 

 than lineola at all stations. L. hylas and its vavietynivescens occurred on 

 the same ground. The common form of L. corydon seemed to be cory- 

 donius, or near that variety; this was especially abundant at Tragacete, 

 and was met with at all other places. The very large pale form Mspana 

 was the commonest at Albarracin, where the corydonius 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 admetufi might not be a dimorphic form of damon. The former 

 was often abundant, the latter always rather scarce. The females, 

 however, have constant difl'erences, 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, tliough very closely allied. 

 L. ddluft, however, seems to precisely occupy the relation to damon that 

 nivescens does to hylas, and that tlie vars. hispava 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 Satynis var. 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 difl'erent, and we never in fact mis- 

 took one for the other. The brown colour is no doubt the original one 

 in the Satyrids, but in this case is more probably a reversion." — Mr. 

 L. B. Prout exhibited a number of Geometridae, also taken by Dr. 

 Chapman and Mr. Champion in Spain. — Mr. F. Merrifield exhibited 

 specimens of Pieris rapm and P. eryane from Dalmatia, showing that 

 the two species are extremely difficult to separate, even if they are not 

 identical. — Mr. C. P. Pickett exhibited varieties of Aryyunis paphia and 

 A. aylaid from the New Forest. — Mr. C. J. Watkins sent for exhibition 

 micro-photographs of the larva in its case and the perfect insect of an 

 Oxyethira, one of the Hydroptilidie, a family of Micro-Trichoptera ; 

 these had been taken by Mr. Mearns, of Aberdeen. Also a drawing 

 made by himself under the microscope of a larva (in its case) of the 

 same genus. — H. Rowland Brown, Hon. Sec. 



South London Entomological and Natural History Society. — 

 October 24th, 1901. — Mr. A. Harrison, F.L.S., in the chair. — Mr. 

 West (Greenwich) exhibited about ninety species of British Homoptera, 

 mainly taken by himself, and which he generously gave to the Society's 

 collection. — Mr. Barnett, a long series of Bryophila muralis (glandifera)
