Exhibitions. 



Mr. M. Jacoby exhibited specimens of the genus Sagra from 

 Eastern Asia. 



Mr. M. Burr exhibited three species of Pseudophyllida', 

 two new species of Cajmoptera (females), and Ca2mo2)tera 

 quadrimaculata, Westw. (female), collected in the Siamese 

 Malay States, by Mr. N. Annandale. One of the specimens 

 illustrated the peculiar methods of offence adopted by the 

 insect when alarmed. Between the head and the pronotum 

 a scarlet hood was visible, the iullation of which bladder- 

 like organ always indicates fear or anger. The other 

 specimens showed the natural position of the head and 

 pronotum. 



Papei'. 



Mr. H. J. Elwes communicated a paper on " Bulgaiian 

 Lepidoptera," and made some remarks on the more notable 

 species which he had taken in the Balkan Peninsula during 

 the months of June and July 1899. The number of species 

 of Ehopalocera captured was 120, which, with a further 20 

 recorded by Lederer, brings up the total to 140. The 

 mountains visited were an extension of the Ehodope range 

 where the climate was particularly rainy, a number of ferns 

 flourishing everywhere, in contrast to the drier Balkans. 

 Some interesting new foi'ms and varieties were encountered. 

 A variety of Colias myrmidone occurred much larger and 

 brighter than the Austrian, and more nearly agreeing with 

 the Ural, form ; and whereas in Austria the white aberration 

 is exceedingly rare, in this locality it predominated. Mean- 

 while the orange forms clearly resembled Colias lieldreichi. 

 The form of C(jenonymplia tiplion met with show^ed an affinity 

 with the Asiatic and not the European form, being almost 

 precisely similar to specimens taken in the mountains of 

 Armenia by Haberhauer. The form of Argynnis pides was 

 intermediate between that found in Greece and the centi'al 

 European Alps, while a form of Erehia was taken similar to 

 the Pyrenean E. gorgone — a curious instance of interrupted 

 distribution.
