basal spur, and apical spines short. Forewings subcoriaceous, 
not transparent, somewhat rhomboidal, veins thick, pterostigma 
incomplete, membrane and veins spotted and mottled. Hind 
wings clear, delicate.

Euphalerus vittatus Crawford (’12: 423). 
One slightly damaged specimen (female) probably of this 
species is at hand, collected at Madhavgiri, Bombay, India ( H . 
H. Mann), May, 1916, on Cassia fistula. The lateral vitta of 
thorax is wanting and the wing is more extensively mottled 
with brown. Structurally this specimen resembles the species, 
but superficially there are some differences. Additional mate- 
rial will show whether or not there are two species in India on 
the same food plant. 
Euphalerus nigrivittatus Crawford (’13: 298). 
This species described from one female. Subsequently three 
additional examples, 1 male and 2 females, of the species have 
been collected by C. F. Baker at Davao, Mindanao. The descrip- 
tion of the male genitalia is now added to the original description. 
Male . — Forceps moderately broad at base, narrowing to mid- 
dle, then abruptly broadened and deeply emarginate at apex, 
terminating in two points ; anal valve longer than forceps, apical 
half much narrower than base. 
The presence of a distinct basal spur on each hind tibia was 
not mentioned in the first description and is now added. 
Distribution. — Luzon, Laguna Province, Los Banos {Baker). 
Mindanao, Davao {Baker).
