data accompany these, but elsewhere the species inhabits 
foliage of Citrus. The species appears to be very widely 
distributed throughout the southern portion of the Eastern 
Hemisphere. 
Genus ARYTAINA Foerster 
Psyllopa Crawford. 
Head nearly or quite as broad as thorax ; vertex usually nearly 
or quite flat, with anterior ocellus visible from above; gense 
produced into conical or subquadrate processes extending for- 
ward nearly in same plane with vertex but separated from ver- 
tex by impressed line. Eyes large, more or less recessive over 
propleurites. Antennse slender, moderately long. Thorax usually 
strongly arched and broad ; propleural suture extending to middle 
of more or less swollen end of pronotum; hind tibiae with or 
without basal spur. Forewings usually broadly rounded, hyaline 
or colored or rarely subcoriaceous, pterostigma present. Hind 
wings smaller, hyaline and clear. 
Key to the species. 
a'. Veins of forewing’ alternately black and yellow or white. 
b 1 . Membrane as well as veins spotted with black or brown; antennae 
less than twice as long as width of head; female genital segment 
not flexed upward at apex. 
o'. Antennae about as long as width of head; forewing with a broad, 
irregular band of brown at apex, and remainder irregularly 
spotted. (Malay Archipelago.) A. pulchra sp. nov. 
c 2 . Antennas nearly twice as long as width of head; forewing without 
apical band, but more uniformly spotted with small maculae.

each outer angle behind antennal base.
