may be figured by Hiibner as C. ruhicundaria; an immaculate form 

 answering to Walker's var. y. The other wider winged form appears 

 to be Hiibner s aurantiaca and with i\\\s ferruginosa of Walker may 

 be synonymous. I have already described the Tariations of C. opeJla 

 (Proc. Ent. Soc. Phil. Vol. 6, pp. 313-314), which is much the stout- 

 est species and think that this and C. quinaria are now readily dis- 

 tinguishable. C. opella has been recently taken in Chautauqua Co., 

 N. Y., and must be added to our lists of New York Bombycidae.
