Clear reddish brown, mottled with small pale spots, especially on 

 the aljdoineii, where the spots have a tendency to arrange themselves 

 in longitudinal rows. Often, but not always, a median light stripe 

 on the dorsal portion of the pronotum, bordered by darker fuscous 

 blotches. The legs paler, the exterior face of the hind femora with 

 the usual darker transverse bars, but not so prominent as in C. 

 maculatus. 



Anterior femora a little longer than pronotum, unarmed beneatJi. 

 Intermediate femora also unarmed or with a single apical spine on 

 front margin. Hind femora about equaling the body, rather stout, 

 the inierior sulcus of average width, rather deep; both earinae of 

 male bearing numerous small serrations, like the fine teeth of a saw, 

 about 25 in number and crowded on the apical two-thirds of the 

 segment; those of the female unarmed ox with a few very fine teeth 

 on the apical third. Hind tibite straight, a little shorter than the 

 femora. Ovipositor less than three-fifths the length of hind femora, 

 the tip upturned a little and pointed. 



Measurements: Male — Length of body, 13 mm.; of pronotum, 5 

 mm.; of front femora, 6 mm.; of hind femora, 1 1 mm.; of hind tibia?, 

 lo mm. Female — Length of bod}'', 16 mm.; of fore femora, (i.o mm.; 

 of hind femora, 15 mm.; of ovipositor, 8 mm. 



C. icrreslris is in Indiana less common than any other species of 

 the genus, having been taken only in Putnam and Yigo counties. 

 The most of those secured v>-ere in April and the specinnens were 

 probably only about half grown. Its general range includes the 

 northern Fnited States and C*anada,east of the Mississippi IJiver.

Dull sooty brown, a little darker on the dorsum of the thora.x 

 where there is usually a narrow median lint' of elay yellow. Very 

 profusely spotted with dull yellow spots, esj)ecially on the posterior 

 margins of the al)doniinal segnumts. Near tlie apex of the liind 

 femora, these spots nearly form an annulation of yellow, more 

 noticeable on account of the more or less dark band beyond.
