Cramer's description and figure of this species were based upon Surinam specimens \ 

 our numerous examples from Central and South America agreeing very well with the 

 figure. A certain amount of individual variation, however, can be traced in our series, 

 chiefly affecting the outer half of the secondaries beneath, the light markings being 

 more extensive in some specimens than in others. On the upper side P. idas much 

 resembles Epargyreus exadeus, but the two species may be readily distinguished by the 

 markings of the secondaries beneath. The Cuban form differs in having the primaries 

 nearly spotless, while in that from the island of Dominica, which we described under 

 the name of Proteides angasi, all the white markings of the underside are replaced by 

 chocolate-red. Mr. H. H. Smith has recently sent us similar specimens from the island 

 of St. Vincent. 



P. idas has a considerable range in altitude in our country, being found from the 

 sea-level to a height of 4000 or 5000 feet. 



The male genitalia have a cleft tegumen ; the scaphium is feebly developed and 

 short ; the harpes are drawn to a point where there is a short spine, the ventral edge 

 curves upwards to meet the dorsal edge, which is much straighter and without a 

 distinct fissure. (See Tab. LXXVIL fig. 5). 



CHRYSOPLECTRUM. 



Chrysoplectrum, Watson, P. Z. S. 1893, p. 24 



Mr. Watson separated this genus from Eudamus chiefly on the peculiar character 

 of the hind tarsi, which have on their under surface two series of thickly set golden 

 spines. These spines are somewhat like those found in Tarsoctenus, but are. not nearly 

 so long ; the terminal tibial spurs, too, are much shorter than in that genus, and the 

 subterminal pair are present. 



The antennae have a moderate club and are bent to a hook, the recurved portion 

 being very slender ; the primaries have a costal fold ; the discocellulars are nearly 

 straight and in a line ; the third median segment is short, about one-third of the second 

 segment, and there is no recurrent nervule from it ; the discocellular of the secondaries
