Sci. 77. 



Nearly the size of G. caesonia; but the primaries are much more 

 pointed at the summit, and the external edge more falcate. 



The primaries have a beautiful, vivid, yellow spot on the disk ; 

 a violet reflection over all the wing ; base powdered with black, as 

 well as the whole length of the anterior edge; a black discoidal 

 point ; the black border of the external edge is wider than in C. 

 caesonia ; it is emarginated, square, somewhat, as in this species, 

 but it encroaches more on the yellow spot so as to nearly touch the 

 discoidal point, which completely destroys the likeness to a dog's 

 head, so distinctly marked in C. caesonia. 



The fringe is rosy, with some yellow spots on each side of the 

 summit. 



The secondaries are beautiful citron yellow, covered over with 

 orange yellow without any spot, only that the trace of the dis- 

 coidal point of the under side is indicated by an orange point. 



The under side of the four wings as in C. caesonia, only that the 

 discoidal point of the primaries is smaller, and the second silver 

 point of the secondaries is larger. Head black ; antenna reddish; 

 thorax black, with some scattered yellow hairs. 



Body black, a little yellowish below.
