The variety ?ioveborace7isis of Dr. Fitch has the orange 

 color of the pronotum distributed in two broad spots on 

 the sides, but in other respects it agrees quite nearly 

 with the normal type distributed throughout the region 

 west of the Mississippi river. A black variety occurs in 

 Utah which lacks entirely the orange spots of the pro 

 and mesonotum. The species extends quite across the 

 North American Continent in the latitude of the great 

 lakes, but while it does not appear south of Boston, in 

 the eastern United States, it spreads along the Pacific 

 highlands from Vancouver's Island to San Francisco.

 The more prominent front of the narrow head with 

 the yellow band across the vertex, the shorter first 

 apical areole, and the yellow banded tergum will dis- 

 tinguish this species from the preceding. It seems to 

 be confined to Utah, so far as is known at present, 

 although the following species may prove to be only a 

 variety of it-

 The type was captured near Denver, Col., and since 

 then other specimens have been secured near San Fran- 

 cisco, and south of that city in the vicinity of San Diego. 

 I have also seen a specimen from near Reno, Nevada.

 Three specimens are all that have yet been reported 

 of this beautiful little species. Two were captured near 

 Los Angeles, Cal., by Mr. Coquillett, and the other was 

 taken near San Diego by Dr. Blaisdell.
