as or slightly longer than basal width, extending forward in same 

 plane with vertex, but separated therefrom by a deep furrow; 

 broadly rounded at apex, a little divergent, hairy. Antennae 

 nearly as long as body without wings. 



Thorax broad and large, strongly arched, hairy. Pronotum 

 long. Legs large and stout ; hind tibise with a prominent spur at 

 base and the apical spines large. Forewings broad, about half 

 as wide as long, light brownish and partially transparent, rounded 

 broadly at apex ; veins not setigerous. 



Abdomen large, short. Female genital segment not as long 

 as rest of abdomen, much smaller, acute at apex, dorsal valve 

 a little longer than ventral. 



Mindanao, Davao (Baker) , 1 female.

This interesting species was described originally as a Psyllopa, 

 but this genus has subsequently been merged by the author with 

 the older genus Arytaina. This species is a pest of indigo in the 

 Orient and probably is the same as Buckton's Psylla isitis, but 

 this identity has not been fully established. Several specimens 

 are before me from Peradeniya, Ceylon, collected by T. B. Fletcher 

 on Indigofera, April 14-17, 1914. 



Psylla colorada sp. nov. Plate I, fig. 13. 



Length of body, 1.6 millimeters ; length of forewing, 2.1 ; width, 

 0.87; width of head, 0.55. General color bright red throughout, 

 except antennal tips and eyes brown or black. 



Head about as broad as thorax, well deflexed. Vertex about 

 half as long as broad ; posterior ocelli elevated on small pedicels ; 

 genal cones a little longer than vertex, strongly divergent, 

 narrowly rounded at apex, sparsely clothed with long hairs. 

 Antennse scarcely two and one-half times as long as width of 

 head, slender. 



Thorax strongly arched. Legs small. Forewings hyaline, 

 veins reddish, membrane uncolored ; pterostigma rather large. 

 Abdomen short. Male genital segment short, small; forceps 

 spatulate, truncate, somewhat toothed at apex, arched ; anal valve 

 a little longer than forceps, long and narrow in profile, tapering 

 to apex. 



Luzon, Laguna, Mount Maquiling (Baker), 5 males. 



This species resembles somewhat Psylla coccinea Kuwayama,
