niacrochaetae : — 1 humeral, 1 praesiitcral, 1 notopleiiral, 1 supraalar, 1 

 interalar, 1 postalar, 2 dorsocentral, 1 scutellar. 



Abdomen flat; (male) ovate in outline, (female) with long, pointed 

 ovipositor; fuscous or similar to thorax in color, covered with white hairs. 



Legs entirely yellow-brown; middle tibia spurred. 



Wings hyaline, with- much lighter fuscous, reticulate pattern than 

 r. crassipes or T. cratericola, but similar to them. The spot in the apex 

 of 3rd sub-costal cell encloses a large hyaline spot, which reduces it to a 

 fuscous ring. The large subquadrate fuscous patch toward the apex of 

 the wing, between the costa and 4th vein, includes from none to 4 small 

 hyaline spots along the costal and apical edges. It sends forth two 

 fuscous rays to the apex, along the 3rd and 4th longitudinal veins, and 

 three toward the posterior border of the wing, (2 crossing middle of 2nd 

 posterior cell and 1 along posterior transverse vein). Eemaining posterior 

 reticulations very pale. 



Habitat : — Oahu : Ohulehule, ex Dubaittia plantaglnea 

 {Terry); Wahiawa, ex Campylotheca {Forbes); Lanihuli 

 {Bridweli) ; Rooke Valley, Kaunniahona and Mt. Kaala ex 

 Dubaufia {Szvecey). 



Tephritis swezeyi sp. n. 



Long. 414-6 mm. al. 5-6 mm. 



Front fuscous and light brown, vertical triangle purplish, with 3 ocelli 

 shining reddish brown; frontal orbits of eye lighter, each bearing 5 large, 

 black bristles; 2 smaller, forward pointing vertical bristles; occiput with 

 single row of pale setae; proboscis, palpi and cheeks yellow-brown, covered 

 with small black bristles; antennae with the two basal joints yellow- 

 brown, third joint subo^■ate, fuscous, with a dorsal, slightly pubescent 

 arista. 



Thorax bluish gray, white shagreen and with white pubescence; three 

 more or less distinct, darker longitudinal stripes, much enhanced by the 

 absence of the white pubescence; median stripe narrower and less dis- 

 tinct, scutellum concolorous, with a broad wedge-shaped, darker central 

 band. Ten niacrochaetae on each side as follows: 1 humeral, 1 post- 

 humeral, 1 notopleural, 1 supraalar, 2 dorso central, 2 postalar and 2 

 large scutellar. Plurae light fuscous, halteres yellow-brown. Legs en- 

 tirely yellow-brown; apex of middle tibia with single large bristle and 

 crown of shorter spines. 



Abdomen same color as thorax or lighter, covered with white pu- 

 bescence and small black hairs, and with strong black bristles on the 

 margins of the segments and sides. Last segment of female dark brown, 

 shining, longer than two preceding segments, bluntly pointed and covered 

 with fine black hairs. Last segment of male abdomen sheath-like, covering 

 genital segments. 



Wings fuscous; anterior half darker. Dark fuscous spot in apex of
