2. Lophophanes inornatus griseus, subsp. nov.

 Colorado to New Mexico and Arizona. 



All specimens of this species from the Middle Province region differ 

 from Californian examples as noted above, the difference being abso- 

 lutely constant in the considerable series examined. The distinctions 

 between the two races may be stated more precisely as follows : 



Var. INORNATU^S. Above grayish olive- brown, beneath grayish white- 

 Wing 2.G8-2.90, tail 2.20-2.60, culmen .38-.40, tarsus .80-.88. Hah.—

 in a very limited space, immediately back of the auriculars. Entire
