ENTOMOLOGICAL CONTRIBUTIONS. 168 



Wings beneath, a lustrous smoky-brown. The tuft supporting the 

 frenulum is rust-red. There are no cellular lunules, and the mar- 

 ginal band of the secondaries is obsolete. 



Expanse of wings 1.85 in. ; length of body, .75 in. In the figure 

 of Guenee, the alaric expanse is represented .28 in. in excess of that 

 given in the description (40mm.). 



This species seems to be the most rare" of our Cucullias, the above 

 example being the only one of which I have knowledge. C. poster a 

 appears to be nearly as rare. A single pair is in the collection of 

 Mr. Meske, and, from their photographs, Mr. Strecker has identified 

 an example in his possession, taken at Falls of Schuylkill, Philadel- 

 phia, Pa. 



?Chariclea exprimens (Walker). 



Caterpillar feeding on rose leaves ; length one inch and one-eighth, 

 head red, body green with yellow lateral stripes, along which a num- 

 ber of black spots are sprinkled. On the first segment, dorsally, are 

 four black spots, on the second are two, and on the terminal (?) seg- 

 ment are four ; these are of a larger size than the remaining ones, of 

 which there are four on each of the other segments, forming a trape- 

 zoid in which the two anterior are considerably nearer the mesial 

 line than the two posterior. 



Taken August 4th, 1859, at Schoharie, and on the 7th August 

 changed to an imperfect pupa, which did not develop. 



It is believed to be identical with other larvae from which C. 

 exprimens has been reared. 



Chamyris cerintha (Treits.). 



Frojn a cocoon made in an angle of a box, the moth emerged May 

 12th. When disturbed, it runs rapidly about the box, without taking 

 wing. Upon suddenly opening the box, it has, in several instances, 

 been observed to drop upon its back and lie in that position, with 

 folded limbs, for several minutes, counterfeiting death. 



It has been captured in the vicinity of Albany, and by Mr. Meske 

 at Sharon Springs. 



Plusia balluca (Hiibn.). 



A moth of the above species emerged from a cocoon July 6th 

 (1861), which was taken about the 20th of June from a hop vine. 

 The cocoon was attached to the under side of a leaf, arid through its
