the subteniiiiuil line. The distinct transverse lines run a little 

 more straiglitly and parallel at internal margin below the internal 

 vein. The costal tooth of the transverse posterior line is a little 

 shorter than in its allies. 



C. Angusi^ may be distingnished by its greenish-gray tint on fore- 

 wings and thorax. It is a little less roughly scaled, and more silky 

 than C. insolahilis. It varies in sometimes showing a strong black 

 basal shade, another from reniform to external margin, and another 

 beyond the transverse posterior line at its last sinus, while in one 

 male specimen these are all wanting except the last, which is feebly 

 indicated. The reniform is large, as in C. residua, which latter 

 species it more nearly resembles on the under surface of tlie wings. 



On the accompanying Plate, figures 1 and 2 represent the male 

 and female of C. Angus i; figure 3 represents C. insolahilis; figure 

 4, C. residua.
