reniform spot moderate, somewliat squarish with a pale brown center, 

 rin<>ed with bhick. Transverse posterior line evenly dentate, with two 

 broadly prominent teeth, broadly marked at its last and deepest inflex- 

 ion at internal margin, followed by an even, broad, brown shade, which 

 occupies the space between it and the sub-terminal line, latter distinct. 

 black, preceded, towards internal margin, by a greyish shade. Termi- 

 nal space with a row of black and greyish dots between the veins. 

 Posterior wings yellow with a basal dark brown shade, internal margin 

 clothed with long dark brown hair. Median band black, absorbed su- 

 periorily by the brown basal shade, much constricted at the disc, taper- 

 ing, sinuate to internal margin. Terminal band broad, black, leaving 

 a small yellow space at external angle and a narrow yellow line from 

 thence to anal angle, streaked five times with blackish at the center 

 of external margin. Under surface dark orange yellow, median bands 

 black, slightly purplish, median band of posterior wings attenuated, ob- 

 solete towards internal margin. Exp. o inches. Coll. Ent. Soc. Phila.

I can detect no differences between C. phalanija, m , and the present 

 species, with which it conforms in the shape of the wings, size, course 

 of the median lines on the anterior, and coloration of posterior, wings, 

 except the distinct black band which follows the transverse posterior 

 line, giving an appearance of narrowness to the sub-terminal space, 

 and the paler coloration of the median space superiorily. 



The following species is regarded by some Entomologists as identical 

 with the foregoing, but I am of opinion that it is very distinct. I think 

 it probable, from determinations I have received from Mr. Walker, that 

 C. palseogama, of the British Museum, refers to the present, and not 

 to the species I have above described as C. palaeogama Gruenee.

Anterior wings brown, varied with blackish, with a paler oblique 

 costal band extending over the sub-reniform spot. Transverse anterior 

 line black, distinct, irregularly undulate with a sub-costal tooth ; me- 

 dian space brown with a broad, oblique, anterior, paler costal shade 

 band which extends over the sub-reniform spot {% ). Reniform spot very 

 large, rounded, ringed with an indistinct brownish line, smaller, more 

 distinct in the 9 ; sub-reniform spot long, pale brownish, oblong, 

 enclosed by ( S ) the transverse posterior line ; transverse posterior
