The characters wliicli distinguish this species from the FAaps fulrhiH 

 are those of <;olor only, as in structural characters the two are identical. 

 Many of the species of the genus dilfer in such characters only, ami 

 they are often very constant. Tiie present species displays ecpial con 

 stancy in the known individuals. 



The specimen alleged by Dr. Yarrow (Check List, p. 82) to have been 

 sent from C-liihualiua, Mexico, belongs to the E. curi/ranllnis. K. disinns 

 has been found only in l-'lorida.

The lu'oportions of the head jdates in this species are very dineieiit 

 from what is observed in E. t'ulrius\\w\ other species, and mark it as 

 one of the most distinct species of the genus. Us geographic range is 

 the Sonoran region, beyond which it has not been found. 



Prof. V. Cragin, of Topcka. Kans., sent me a specinu-n of this species 

 whicli he obtained at (luaymas, on the (iulf of Calilbinia. The speci- 

 men (112;5) from the liio Crande Hiver, referivtl to (his >pecies by \ .w- 

 row (Check List, p. 82), belongs to the IJ./iilrliis.
