 the territories north of New Mexico, although it is found in Canada, 

 not far from Quebec. The males usuallj' have a smaller emargination 

 of the front of the clypeus than the females ; and they are also more

Inhabits" Texas, New Mexico, and the Southern States. The variety 

 S. Jimbriatus, Dallas, extends as far north as Massachusetts, while it is 

 not uncommon in all the States north of Yirginia. Almost all the vari- 

 eties, from an almost uniform yellow Jimbriatus through the red and blue 

 diana to the uniform violet violacea, have passed through my hands. 

 The latter variety has been taken once near Pliiladelphia ; in Georgia ; in 

 Florida; and once, also, in Texas by Mr. Boll.
