 Unquestionably a Calliovima allied to C. lufesceiis. 



7. Calliohma lutescens.

I found this insect associated with C. thorafes in the genus Pergesa. 



S. Calliomma thorates.

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. thmates and C. licastus. 

 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.

On account, probably, of the difference in the sexes, and the difficulty of at once recog- 

 nizing them, Mr. Walker confounded this species with E. camerfus, gorgon, and danum.
