with white. Secondaries dark smoky brown with traces of reticulation and 

 darker checqiiering on fringes, which show traces of white at anal angle. Be- 

 neath, primaries, smoky, silvery gray along inner margin ; costa gray with 

 black spots ; traces of strigae over whole wing ; fringes as above ; secondaries, 

 pale gray, lighter along costa, which is striped with black ; some traces of 

 reticulation give a powdery appearance to wing; fringes dark brown. Ex- 

 panse, 29 mm."

The faint dot at end of cell, combined with the dark brown mark- 

 ings is sufficient to distinguish this species from anna Dyar, and it dif- 

 fers from marga B. & McD. in possessing the white line on basal half 

 of inner margin. 



SUBFAMILY ZEUZERINAE 



Zeuccrinae Neumoegen & Dyar, Jour. N. Y. Ent. Soc, II, p. 160 (1894). 



This subfamily is represented in N. America by two genera, 

 Zeuzera and Hamilcara, both possessing a strong frenulum and one 

 pair of apical spurs on hind tibiae. Apart from the fact that the 3 

 antennae are only pectinate on basal half, this group differs from the 

 other subfamilies in that veins R and M, of secondaries are widely 

 separated by a disco-cellular bar and not stalked or from a point as in 

 the other species ; the anal veins of primaries are not connected by a 

 cross-bar.
