Synopsis of species of Eremotyhis

 male clasps rather long, subrectangular, obtusely rounded at the 



apex m a c r u r u s Linn.

Eremotylus macrurus Linn. 

 Long-tailed Ophion 

 This, the largest American species of the genus, is closely allied 

 to Erem. arctiae Ashm., which has been confused with it in 

 collections. The two species are easily separated from the others 

 of the genus by their considerably larger size; the smallest being 

 perceptibly larger than the largest of the other species, excepting
