On one occasion, in the early part of Jnne, this species occnrred in 

 considerable numbers near the city of Baltimore, but since that time not 

 a single specimen has been captured in this vicinity.

 America, Walrussia, Canada, Massachusetts, and south to Pennsylvania. 

 In York County, in the latter State, I collected a few specimens, in 

 the month of August. 



It varies very much in color and in the amount of black upon the 

 tergum, so that it seems to include the European C. crassicornis, Linn. 

 One variety has the black bands of the couuexivum reduced to mere 

 points. Eobert Kennicott collected specimens in the vicinity of the 

 Mackenzie Eiver, and also near the Yukon Eiver. Mr. Scudder kindly 

 gave me a specimen from the regiou of the Saskatchewan, and Mr. Keu- 

 uicott collected others in the same locality. Unfortunately, his specimens 

 have been lost to science by the great fire in Chicago. 



Like C. lateralis and G. hyaUnus, this species becomes suffused with a 

 red color, which totally changes its appearance. This is also sometimes 

 conspicuously the case in very soft recent specimens.

The rufous stripe on- the sides of the body underneath are sometimes 

 changed from red to fuscous, and are occasionally obsolete. 



In Maryland, it may be found by beating rank growths on the borders 

 of woods; the first brood late in May to early in July, and a second 

 brood in August, September, and October. It lives over winter iu the 

 adult state,
