attached to the trunks. The pupa is covered with a bluish 

 eiilorescence, enclosed in a slight cocoon of silk, spun amongst 

 leaves or bark. C. piatrix Grote is brown on the anterior 

 wings and varied with black, while the hind wings are yellow 

 with u broad median and marginal band. It is common in the 

 Middle and Eastern States. 



C. ultronia Hubner (Plate 8, fig. 4 ; a, larva) expands two 

 and a half inches and is of a rich umber color, with a broad 

 ash stripe along the middle of the wings, not extending to- 

 wards the apex, which is brown. The hind wings are deep red, 

 dusky at base, with a median black band, and beyond is a red 

 band a little broader than the dark one, while a little less than 

 the outer third of the wing is blackish. The larva feeds on 

 the Canada plum. It is gray with black punctures, and the 

 head is edged with black. The segments are transversely 

 wrinkled, and on each one are two whitish and two brownish 

 papillae ; the two brown ones on 

 the eleventh ring are much 

 larged, and on the ninth ring 



small brownish horn. On the />~ J>

 sides of the body, before the spir- 



acles is a line of light pink fila- 



ments fringing the scalloped sides. On July 15th the larva 

 changed to a chrysalis in an earthen cocoon, and the moth ap- 

 peared on the 2d of August. 



Druxtcriti is a small, grayish moth, with two geminate black 

 dots near the apex, and a broad diffuse line on the fore wing. 

 The larva is a looper, and the body is attenuated at each end. 

 D. erechtea Cramer flies very abundantly in grass lands in May 

 and early summer. Mr. Saunders informs me that the larva 

 (Fig. 247) is "one and a quarter inches long and walks 

 like a geometer ; the body is thickest in the middle, being 

 somewhat smaller towards the head, but tapering much 

 more posteriorly, while the head is not large and is rather 

 flattened in front and is pale brown, with darker longi- 

 tudinal lines. The body above is reddish brown, with many 

 longitudinal darker lines and stripes ; there is a double whitish 

 dorsal line, with a stripe on each side of the darker shade, 

 another stripe of the same hue on each side close to the stig-
