ZTdi^iM— Nevada, (Coll. R. H. Stretch.) 



Described from a single specimen taken near Virginia City, Nevada, 

 by Mr. William Eaves of that place. This species approaches K. tricolor 

 much more closely than the two Californian species, inasmuch as the 

 body parts are clothed with much shorter hairs, and the whole appear- 

 ance of the insect is less woolly. Of its habits I can add nothing.
