Synopsis of species of Eremotylus 



a Cubitodiscoidal vein usually strongly sinuate; hooks of hind wings 13-15; 

 male clasps rather long, subrectangular, obtusely rounded at the 



apex macrurus Linn. 



a a Cubitodiscoidal vein nearly arcuate ; first and second recurrent ner- 

 vures nearly equal ; hooks of hind wing 7-9 ; male clasps subrectangu- 

 lar, acutely rounded arctiae Ashm.

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 



a See account of this species, p.106.
