Plate IV. 



Up to the present, representatives of the Satyrid genus 

 Calisto appear to have been rather scarce in collections of 

 Exotic Lepidoptera, and consequently little is known of 

 them. Kirby, in his " Catalogue of Diurnal Lepidoptera," 

 p. 108, enumerates four species only, and to my knowledge 

 none have been added since, the last described being 

 C. archehates, Men., in 1832. Recently Mr. Herbert J. 

 Adams, F.E.S., has received several fine collections of 

 Lepidoptera from Haiti, and I myself collected in Jamaica 

 during the latter part of 1897 and the early part of 1898, 

 with the result that good series of most of the species 

 inhabiting these islands have been obtained. As two of 

 these are new, as well as a third from the collection of the 

 late Ed. G. Honrath of Berlin, and now in the possession 

 of Mr. Adams, and as some of the species are very closely 

 allied, I tliink that an account of the genus may be of use 

 to Lepidopterists. 



Calisto may be separated from the allied genera by the 

 peculiar position of the 1st subcostal nervule, which leaves 

 the nervure after the end of the discoidal cell. The true 

 home of the genus appears to be the West Indies, though 

 some are found in Central America. Kirby, in his " Cata- 

 logue," and Cramer (Pap. Exot.) give Carolina and 

 Pennsylvania respectively as localities for C. zangis, Fabr., 

 while Mr. Adams has a single female of this species from 

 Demerara,
