Type of genus. — Sphinx ephemeraejormis Haworth, 1803.

Male.^ — Medium to relatively large moths, very stout, densely 

 hairy body. Antennae (fig. 383) broadly bipectinate, individual seg- 

 ments short, stocky; those of basal fourth broader than long, gradually 

 longer, more slender toward apex; pectinations more or less com- 

 pressed, long near base of antenna gradually diminishing in length 

 before apex, distal fourth or fifth strongly serrate. Prothoracic legs 

 (fig. 187) longest, without epiphj^sis. Meso- and metathoracic legs
