NATURAL SCIENCES OF PHILADELPHIA. 91 



60. Heliconius Guarica, nov. sp. 



Upper surface dark brown, glossed with bluish black ; anterior wings crossed 

 by a broad central transverse scarlet band, abruptly terminating after the 

 first median veinlet, and not touching the outer margin ; posterior, immacu- 

 late. 



Underneath, the band becomes pale rosy white, edged only with dark pink ; 

 the costa of forewings, presents a short basal scarlet bar, that of the hind 

 wings a longer yellow one ; upon these are also five basal spots, one yellow, 

 surrounded by four scarlet ones. 



Body black, with some yellow stripes on thorax below and a yellow ventral 

 stripe ; some yellow spots on the collar ; first and second joints of palpi 

 yellow ; third black. Antennae black. 



Expanse 2*65 inches. 



Hab. — Insagasuga, New Granada. (Coll. Tryon Reakirt.) 



Closely allied to HI. Hydara, Hewits, but constantly diifers in the absence 

 of a scarlet spot on the upper side of the secondaries. 



In the same number (63) of his " Exotic Butterflies," he has redescribed 

 Cal/idryas Thauruma, Reakirt, as Call. Fiaduna ; his name must therefore be 

 regarded as a synonym.
