plane with vertex, divergent, subacutely pointed. Antennae less 

 than twice as long as width of head, slender. 



Thorax broad, arched, legs rather short; hind tibiae without 

 basal spur, and apical spines short. Forewings subcoriaeeous, 

 not transparent, somewhat rhomboidal, veins thick, pterostigma 

 incomplete, membrane and veins spotted and mottled. Hind 

 wings clear, delicate. 



Abdomen short. Male forceps about two-thirds as long as 

 anal valve, narrow, subacute at apex, sides parallel; anal valve 

 longer, slender, broadest at base, upper third narrowed. 



Fiji Islands, Rewa (Muir), March, 1906, 3 males. 



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 Bahos (Baker). 

 Mindanao, Davao (Baker).
