698 FAUNA HAWAIIENSIS 



(2) Pipunathts acroihrix, sp. nov. 



Female black, the abdomen shining metallic aeneous-black. Face below the 

 antennae with dense white tomentum, that on the head posteriorly more fuscous. 

 Third antennal joint clear yellow, the beak thin and long, white. Mesonotum with 

 thin fuscous tomentum, dense only at the sides, sparsely and shortly pilose ; marginal 

 bristles of scutellum well developed ; metanotum and pleura with denser yellowish grey 

 tomentum. Wings long and clear, neuration as in P. vtdcanus, stigma brown, about 

 half as long as the fourth costal segment. All the coxae dark, the trochanters and 

 tibiae all clear yellow, the femora of this colour at base and apex, the middle being 

 black, the tarsi, except the basal joint, being more or less dark above. Posterior tibiae 

 with three or four long bristles outwardly near the middle. Abdomen with a distinct 

 band of pale tomentum on the basal segment, the rest brightly shining and clothed with 

 short hairs, the fifth at the apex with many long black bristles. Length 475 mm. 



Very distinct by the colour of the legs, bristles of hind tibiae, the metallic colour 

 and clothing of fifth abdominal segment. 



Hab. Hawaii, Kilauea. Male not known to me. 



(3) Piptmctihis pyrophilus, sp. nov. 



Deep black, more or less shining, especially the male, the very sparse tomentum 

 of the surface being mostly fuscous and nowhere conspicuous, except perhaps an apical 

 band on the first abdominal segment of the female. Legs in both sexes entirely black, 

 or at most a trifle reddish or pitchy at some of the articulations. Antennae entirely 

 black ; the face of the female above the antennae not at all shining. 



General appearance that of a minute P. vidcamis, but easily distinguished by being 

 even more entirely black in both sexes ; by the erect hairs of the mesonotum, which are 

 unusually long, and as well, or almost as well, developed as the scutellar bristles. Wings 

 smoky hyaline, differing very little in the sexes, though rather darker in the male. 

 Stigma very short compared with the long fourth costal segment. Neuration generally 

 as in P. vulcanus. Abdominal hairs black, longer in the female than in the male. 

 Length 3 mm. 



Hab. Hawaii, Kilauea. Attached to one or both of the small Delphacid leaf- 

 hoppers, that are so common on Raillardia around the crater. 



(4) Pipunculus holoinelas, sp. nov. 



Female entirely black and for the most part shining, the antennae entirely dark, 

 piceoVs. Mesonotum apparently without tomentum (? abraded) shining and with very 

 short erect hairs, metanotum with greyish tomentum. Halteres pale in the middle, 

 more or less dark at base and apex. Legs with the coxae and femora black, the
