ments are concave or so deeply hollowed that the sides and upper 

 surface appear quite thin. 



Male. — Hind-bod\< elongate-oval, terminal segment rounded 

 and not prolonged ; on each side of the uncovered second seg- 

 ment there is a small cluster of fine black setae ; these do not 

 occur in the other sex. 



This species differs from Froggatt's Tcphritis psidii in being 

 larger, differently colored and sculptured, and without dusky 

 areas on the wings. From T. tryoni it is distinguished by the 

 greater length of the body and expanse of the wings, uniform 

 coloration, without fuscous or yellow marks, dissimilar clothing 

 and sculpture, less broadly oviform or wasp-like hind-body, and 

 stouter antennal setae. In T. tryoni the flanks of the sternum are 

 fuscous.

Froggatt states that the larvae of this species were first found 

 in infested guavas condemned in a shipment from Noumea, New 

 Caledonia. Specimens were later taken in a shipment of grana- 

 dillas from Fiji. Froggatt's description follows: 



This is a medium-sized species, measuring 3 lines in length and 

 about 5 across the expanded wings. The head light-brown, with 

 rich metallic purple eyes ; antennae brownish-yellow, the last joint 

 black, long and cylindrical, finely pubescent, the bristle stout and 

 long, with scattered bristles on the face and hind margin of the 

 head ; thorax black, with a few fine bristles near the base of the 

 wings, a broad parallel white stripe down the center, with a pale 

 yellow stripe down either side, the humeri a stripe on the sides 

 marked with creamy wdiite ; the scutellum large, angular, broadest 

 in front, so broadly margined .with creamy white that the center 

 forms a black triangle, a pair of black bristles ornamenting the 

 hind margin ; legs brownish-yellow, clothed with fine hairs, tarsal 

 spines and claws black ; the wings hyaline, very slightly clouded 

 at the tips ; nervures blackish ; the transverse cubital nervure 

 clouded on either side with black, giving it a thickened appear- 

 ance ; the apical portion of the second costal, the base of the third 

 costal, and the third basal cell clouded with brown ; the abdomen 

 black, elongate, narrow at base, pointed to extremity ; the geni- 

 talia ochreous ; ovipositor consisting of a stout horny pointed 

 process, enclosed in a pale yellow sheath of a granulated structure.
