This species is very closely allied to (7. femur-rubrum^ 

 from which it is to be distinguished by the greater prom- 

 inence of the front ; by the greater globosity of the eyes ; 

 by the markings of the wing-covers and hind legs, and the 

 sculpture of the valves of the ovipositor ; the wing-covers 

 are of the same color as in C. fe mur-rubrum, 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 upon the outside alternate, transverse, 

 straight bands of black and brownish-yellow, three of each 

 in number ; hind tibiae brownish-red with black spines, 

 with a narrow black annulation at the base, followed by 

 a wider yellowish one ; the upper valves of the ovipositor 

 are not curved so deeply on their upper surface, nor so 

 upturned and pointed at their tip as in C. femur-rubrum ; 

 the lower valves, too, are much straighter, bent downwards 

 scarcely at all at their tip, and the lateral tooth, so apparent 

 in C. femur-rubrum^ is here almost obsolete. 



Length of body, 1.1 in. ; of wing-covers, .69 in. ; of hind 

 femora, .48 in. ; 1 9 . I have seen only a single specimen 

 sent me by Mr. Uhler under the above name.
