short, dark hairs; basal segment with the lateral bristles well de- 

 veloped, and more or less evitlence of a grey apical tomentose 

 band, possibly partly worn off in the specimen described; geni- 

 talia yellowish apically. Length 4 mm. 



HAB. Oahu, Honohilu; a specimen taken in the mountains 

 by Mr. O. H. Swezey. It is a most distinct species, possibly 

 parasitic on the common little green Delj^hacid that fretinents 

 the Frcyclncfia. 



31. P. Jiaivaiiciisis, sp. nov. 



V^ery closely allied to P. sivcacyi, from which it differs as fol- 

 lows; the basal joints of the antennae are ferruginous, as seen 

 laterally, not dark brown or piceous; the mesonotum is very dis- 

 tinctly covered with greyish tomentum at the sides in front as 

 also is the scutellum; the small cross- vein is rather nearer the 

 base of the discal cell, and the wings are of a more yellow tint. 



Abdomen fuscous, and distinctly aeneous, the basal segment 

 and sides of the others with grey tomentum, the surface hardly 

 shining, except towards the apex of the body. Legs as in the 

 preceding, but the posterior tibiae with two or three specially 

 developed bristles on the median dilatation outwardly. Length 

 4 mm. 



HAB. Hawaii ; one specimen taken some years ago in a gulch 

 in the Hamakua district. 



32. P. nwlokaiciisis Grimsh. 



P. iiiolokaiciisis Grimshaw, l-'auna Hawaiiensis Vol. JH, Pt. i, 

 p. 17. 



HAB. Molokai; it was common in the forest in 18(^3 but I 

 only took two or three specimens. 



33. P. iiigrofarsafiis Grimsh. 



P. iiigrotarsatiis Grimshaw, !oc. cit. p. 18. 



HAB. Kona, Hawaii. 4000 feet. I have some suspicion that 

 this may be identical with P. jitvator described above, but none 

 of the specimens of the latter seem to quite agree with it. 



34. P. rotundipcnnis Grimsh. 



P. votuiidipctinis Grimshaw, loc. cit. supra. 

 HAB. Kilauea, Hawaii, T'896.
