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. Antennas 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 1 . Veins of forewing alternately black and yellow or white. 



6\ Membrane as well as veins spotted with black or brown; antenna? 



less than twice as long as width of head; female genital segment 



not flexed upward at apex. 



c\ 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\ Antennae nearly twice as long as width of head; forewing without 

 apical band, but more uniformly spotted with small maculse.

 each outer angle behind antennal base.
