[851 ON SOME NEW SPECIES OF CEEUEA. 197 



From 3 &amp;lt;$ s and 6 ? s, in the Collections of Messrs, von 

 Meske, Tepper, Riley, Strecker and Lintner. 



The seven black spots on the white ground intermediate to 

 the bands, arranged in an ellipse as above described, readily 

 distinguish this species from any other of the genus. 



It is closely allied to the C. bicuspis of Europe. Mr. A. G. 

 Butler, of the British Museum, to whom I communicated an 

 excellent photograph of it, writes : &quot;it precisely agrees with 

 some of our European examples of bicuspis&quot; Dr. Speyer 

 who has received an example from Mr. von Meske, remarks 

 of it : &quot; it is very near to bicuspis&quot; 



Although quite dissimilar in color from C. cinerea Walker, 

 yet it is closely related to that species in the form of the bands 

 (often imperfectly defined in cinerea) and in the arrangement 

 of the intermediate nervular spots. 



The moth has been reared from larvae found by Mr. F. Tep 

 per of Flatbush, L. I., feeding on wild cherry, when near their 

 maturity. I am indebted to him for the following note in re 

 gard to them. &quot;They are of the same shape as borealis [pcci- 

 dentalis ] but differently colored. Instead of the green of that 

 species, the color is greenish-yellow, the dorsal patch is rather . 

 smaller and of a brighter shade, and the minute spots on the 

 sides are more delicate and brighter. The examples met with 

 have been larger than borealis and somewhat heavier in ap 

 pearance. Three mature larvse were taken by me between the 

 10th and 15th of July, 1875 ; one was ichneumonized ; the 

 other two spun up in the same manner as borealis^ within a 

 few days after their capture, and the moths emerged in from 

 two to three weeks.&quot; 



In Smith and Abbot s Insects of Georgia it is said of it : 

 &quot; The caterpillar was taken the latter end of July, feeding on 

 that kind of poplar vulgarly called the cotton-tree. When dis 

 turbed, it shoots out of the ends of its forked tail two soft 

 orange-colored threads. Early in August it shed its skin, and 

 on the 10th of that month it inclosed itself in a case made of 

 chips of wood and affixed to a branch. The moth came out 

 April 24th. It likewise feeds on the wild cherry and willow, 

 and is found also in Virginia, but it is a very rare species.&quot;
