LEPIDOPTEROLOGIE COMPAREE 



— D"" T. A. Chapman exhibited spécimens of Callophrys avis, 

 a new species from the South of France, first taken by him at 

 Hyères three years ago, and in the following year, and now 

 obtained by him this year from the Pyrénées-Orientales. It is very 

 closely allied to C. ruai, but distinguishable by its larger size, 

 ruddier colour, red hairy face without silver Hnes round the eyes, 

 the very différent form of the androconial band, the red underside 

 to the club of the antennae, the différent tone of the green of the 

 underside and the différent character of the white line. 



It has probably been passed over in the field as merely ruèi, 

 but could hardly be so in the collection, though the only spécimen 

 seen by the exhibitor, and not in his own possession, is one in 

 the Natural History Muséum at South Kensington, séries of 

 C. nibi, labelled « Tangier, Elwes coll. » The species is doubtless 

 scarce and local. D"" Chapman said he hoped to submit later a 

 paper on the species giving some détails of habits and life history; 

 he thought it better not at présent to forestall any interest that 

 communication might possess. 



He ventured to say, however, in case the présent exhibit left 

 any doubt as to whether C. avis might not be merely a variety 

 of C. nibi, that there were great différences in the larvae, of 

 which also he exhibited examples in the last instar. The most 

 remarkable was perhaps in the first stage. In two species, so closely 

 allied, one rather expected there would be no appréciable diffé- 

 rence between them in the hrst stage. There were, however, not 

 only différences of colour and markings, but notable différences 

 in the development of the hairs. »

 français qu'il l'est en anglais, sa langue maternelle.
