even when shot at. When flying they utter a note like "caff a, caff a," 

 and on the ground run clumsily and slowly, generally forming a line. 

 In Northern Tibet they were frequently heard flying about at night ; 

 but no cause could be found to account for this strange behaviour. 

 The Kokonor basin, according to Prjevalsky, forms the northern aud 

 probably also the eastern limit of its geographical distribution.

4. Descriptions of nineteen new Species of Diurnal Lepi- 

 doptera from Central America. By F. DuCane Godman 

 and Osbert Salvin. 



[Eeceived Jan. 18, 1878.] 



Nearly half of the species described in this paper have been sent 

 us during the past year by Mr. II. Rogers from Costa Rica, where 

 he has been collecting on the slopes of the volcano of Irazu. The 

 rest of the species are selected from unnamed specimens in our col- 

 lection, some of them from Guatemala and some from Mexico. 

 Figures of most of them have been prepared and will be published 

 shortlv. Specimens of all the species are in our collection.
