 at tips. Female genital segment about half as long as abdomen, thick 

 at base and abruptly converging to acute apex, valves subequal in 

 length.

 2500 ft.), bred from conical galls on leaves of Pelea clusiaefo- 

 lia and P. lydgatei,. August 20, 1917 (Crawford) ; same local- 

 ity on foliage of Pelea (Swezey) ; Wailupe, January 23, 1915,

 areas. Body surface covered sparsely with stiff hairs. 



Head not quite as broad as mesothorax, much narrower than meta- 

 thorax, deflexed ; vertex not quite twice as broad as long, with a deep 

 discal depression on each side of median suture, sharply elevated on 

 posterior margin, with a few stiff hairs near posterior ocelli. Genal

 sub-basally. Female genital segment short, thick at base, abruptly con-

Distribution: — Island of Oahu — Mt, Tantalus (Perkins); 

 Kaumuohona (Swezey), 1 female determined by Kirkaldy; 

 Mt. Olympus, elevation 2000 ft. (Swezey) ; Wailupe, January 

 23, 1915 (Swezey) ; Palolo Hills, on foliage of Pelea rotundi- 

 folia, many males and females. The life habits of this species 

 are not well known.
