of the damage to her ovarian tubes. Over thirty per cent, of 

 P. vitiensis were stylopized, and quite forty per cent, of the para- 

 sites were males. 



(2) PIPUNCULUS. 



The parasitic flies of the genus Pipunculiis appear to be very 

 scarce in Fiji, as compared with Australia, where Koebele and 

 Perkins found them abundantly in all localities. The following 

 very distinct new species was, however, obtained : 



Pipuncuhis vitiensis, sp. nov. 



Male. Face, frontal triangle and occiput, black with whitish 

 tomentum ; sparse near vertex, denser below ; antennae yellow 

 with apex bluntly pointed. 



Thorax black ; mesonotuni shining, without tomentum, pleura 

 and metanotum with whitish tomentum ; wings clear, iridescent, 

 with dark neuration, stigma yellowish brown, enclosed basally by 

 a strong cross-vein beyond termination of mediastinal vein, pos- 

 terior cross-vein before the apex of second longitudinal, third 

 costal area longer than fourth ; halteres yellow ; legs uniformly 

 yellow. 



Abdomen yellow, last segment and hypopygium black, sparsely 

 covered with black hairs ; basal segment with three or four bristles 

 on each side. 



Dried specimens appear to have a black band upon second seg- 

 ment not noticeable in fresh specimens, evidently caused by the 

 dried up viscera. 



Length, 3 mm. 



Female. Head black; face with whitish tomentum, front with 

 whitish tomentum at base of antennae and along frontal orbits ; 

 whitish tomentum very sparse on occiput near vertex ; denser 

 below. 



Thorax lighter than in male, dorsum more inclined to brown, 

 and pleura yellowish fuscous with whitish tomentum. 



Abdomen and ovipositor yellow, the two posterior tergites 

 fuscous. Length, excluding ovipositor, 2^ mm. 



HAB. Rewa, Fiji. A male and female taken together from 

 boughs of trees, so that, like P. hctcrostiginns, it nrobably attacks 

 arboreal leaf hoppers. 



The stigma being enclosed basally by a cross- vein, places this 

 species near P. hctcrostiginns. Perk., but it can be at once distin- 

 guished by the shining thorax and yellow legs.
