In the Seventh Report of the State Entomologist of Illinois, that 

 for 1878, the occurrence of the species at Carbondale is noted by 

 Prof. French, brief descriptions of larva and imago are given, and 

 mention is made of its injuries to the rose. 



A description of a larva of an allied species, Pyrrhia angulata, 

 (according to some authors identical with this), was given by Mr. 

 Coquillet in the first volume of Papilio (18S1). In Volume X of the 

 Transactions of the American Elitomological Society (1883), Mr. J. 

 B. Smith figures the fore wing of both these species, (considering 

 angulata a variety of umbra), and quotes Mr. Coquillet's description 

 of the larva of the former. By Smith the species is placed under 

 the genus Chariclea. On page 259 of the same volume, Mr. A. E. 

 Grote objects to this generic assignment and insists upon Pyrrhia 

 as the proper generic name for the species, not considering Chariclea 

 a homogeneous group, as defined by its author. He also insists 

 upon the specific distinctness of angulata. In the third volume of 

 Papilio, pages 135-36, Messrs. Edwards and Elliot give descriptions 

 of the full-grown larva and pupa of this species under the name of 

 Pyrrhia cxjjrimens, and mention Desmodimn as a food plant. 



DESCEIPTION. ' 



Lfln'a. ^The full-grown larva is 1.36 inches in length, pale bluish 

 white above and greenish beneath, with a bright lemon-yellow stripe 

 along the side, including the stigmata, and above this a pale bluish 

 stripe of about the same width heavily bordered with black above 

 and beneatli. The dorsal and sub-dorsal regions are pinkish bluish 

 white, marked with irregular specks and lines having a tendency to 

 arrange themselves in five black stripes most conspicuous on the 

 second and third thoracic segments. 



The head is pale chestnut, inclined to orange ; cervical shield 

 nearly covered by eight large square black blotches in two rows of 

 four each, the middle blotches of the posterior row being much the 

 largest of all ; abdominal segments each with four large conspicuous 

 piliferous black tubercles upon the dorsum, one in front of the spiracle, 

 one just below the edge of the yellow stripe, and another above the 

 base of the proleg. The jointed legs are all black, prolegs shining 

 black without and dusky at the tip. The anal segment is widely 

 bordered with black posteriorly, and a broad black patch extends 

 forward from the middle of this arc. On the two segments preced- 

 ing this, the dorsal piiiferous tubucles are much more conspicuous 

 than elsewhere. Spiracles black. 



Pupa. — The pupa is three-fourths of an inch in length, shining, 

 dark brown, the spiracles slightly darker, surface smooth except for 

 some large punctures on the abdominal segments ; abdomen termi- 

 nating in t\yo slender, slightly hooked spines. 



Imago. — The front wings and thorax of the imago are brownish 

 orange, varied with yellowish, hind wings pale yellow at base, brown- 

 ish red on posterior half. Examined with a glass the brown color 

 of the front wings is seen to be irrorate with reddish scales. Trans- 

 verse anterior line red, zigzag with three angulations ; orbicular well 

 marked, of the ground color of the wing ringed with red. Middle
