C. piincfnlatn^, Uhler, in Scudd. Bost. Jour. Nat. Hist., vii, 465. 



This species is very closely allied to C. femur-ruhrum, from which it is 

 to be distinguished by the greater prominence of the front; by the greater 

 globosity of the eyes ; by the markings of the elytra and hind legs, and the 

 scidptiire of the female abdominal appendages. The elytra are the same 

 color as in C. femur-ruhrum^ with the square, dark spots not limited to a 

 medial band, but found equally above and below this, extending nearly to the 

 tip. The hind femora have, on the outside, alternate, straight bands of black 

 and brownish-yellow, three of each in number: hind tibiae brownish-red, 

 with black spines, a narrow black annulation at the base, followed by a wider 

 yellowish one. The upper corniculi of ovipositor not curved so deeply upon 

 their upper surface, nor so upturned and pointed at their tip as in the C. 

 femur-ruh-um ; the lower corniculi much straighter, scarcely bent down at 

 the tip; and the lateral tooth, so apparent in C. femur-rubrum, is here almost 

 obsolete. Possibly a variety of tlie latter species. 



Dimensions. — 9 Length, 1.1 inches; elytra, 0.6d; posterior femora, 0.48 

 inch.

''Grrizzled with dirty olive and brown; a black spot extending from the 

 eyes along the sides of the thorax ; an oblique yellow line on each side of the 

 body beneath the wings; a row of dusky, brown spots along the middle of 

 the wing-covers; and the hindmost shanks and feet blood-red, with black 

 spines. The wings are transparent, with a very pale greenish-yellow tint 

 next to the body, and are netted with brown lines. The hindmost thighs 

 have two large spots on the upper side, and the extremity black ; but are red 

 below, and yellow on the inside. The appendages at the tip of the body in 

 the male are of a long triangular form. Length from 0.75 to 1 inch ; expan- 

 sion of wings 1.25 to 1.75 inches." 



As this species, which is so common, varies considerably, I have con- 

 cluded to give Dr. Harris's description without change, adding the following:
