Philampelus calliomene, Schaufuss, Nunquam Otiosus, i. p. 19 (1870). 
Venezuela. 
Unquestionably a Calliomma allied to C. lutescens. 
7. CALLIOMMA LUTESCENS. 
Calliomma lutescens, Butler, P. Z.S. 1875, p. 5, pl. i. fig. 6. 
Haiti (Tweedie). Type, B.M. 
I found this insect associated with C. thorates in the genus Pergesa. 
8. CALLIOMMA THORATES. 
Oreus thorates, Hiibner, Zutrige, figs. 525, 526 (1825). 
Peryesa thorates, Walker, Lep. Het. viii. p. 151. no. 2 (1856). 
Haiti (Tweedie); St. Thomas (Hornbeck); St. Vincent (Doubleday); Oaxaca (Hart- 
weg); New Granada. B.M. 
Mr. Walker has been followed by Messrs. Clemens, Morris, and Grote in his reference 
of this species to the genus Pergesa; the latter appears, however, to be an exclusively 
Old-World group, with much less waved margins to the wings, and generally more 
prominent vertex to the head; the coloration of the primaries also shows a different 
character, whilst there is much in common between those of C. thorates and C. licustus. 
So far as I can see, the principal reason for the exclusion of C. thorates from Calliomma 
was the absence of the silver spot on the primaries; yet its position is indicated by a 
pale spot on the under surface. 
Genus 21. Enyo, Hiibner.

Honduras (Dyson); Santarem (Bates); Rio (Stevens); Brazil (Doubleday). B.M. 
On account, probably, of the difference in the sexes, and the difficulty of at once recog- 
nizing them, Mr, Walker confounded this species with FL. camertus, gorgon, and danum.
