about equal in length to the hind coxae. The surface of the 

 wings is uniformly clothed with short dark hairs. Length i nnii. 



Hab : Hawaiian Islands : parasitic in eggs of Rcdiiz'iohis black- 

 biinii. 



N. B. — A second species closely allied to this, but differing 

 slightly in color, and with a shorter marginal vein has probably 

 similaj habits, as also P. hazcaiicitsis described by Ashmead. 

 (Faun. Haw. Vol. i, p. 332,) which agrees in nearly all structural 

 points with the one here described. These two species are 

 usually bred from leaves covered with Aphis and might easily be 

 supposed to be parasitic on plant-lice by a careless investigator. 



Ala phis, Hal.' 



Antennae of female 8-jointed, the scape elongate, the second 

 joint dilated and much wider than the following, third slender, 

 elongate, rather shorter than the fourth, 5th, 6th, and 7th, in- 

 creasing* in width, club nearly as long as the four preceding. 

 Antennae of male lo-jointed. the scape elongate, second wider 

 than the following, third elongate, but shorter than the fourth, 

 which is subequal to the following joints. Posterior ocelli close 

 to the eye-margins, the three forming a triangle with extremely 

 wide base. Tarsi 5-jointed. Abdomen sessile. (Plate XH, 

 fig. 5 ; antennae of female in two aspects and that of the male.) 



Alaptns inimatiinis, sp. nov. 



Female: Pallid ochreous, the head sordid and also the 

 thorax along its posterior margin; abdominal segments with 

 obscure sub-quadrate, lateral, blackish or sordid spots. Anten- 

 nae with two basal joints pale, the rest dark. Length § mm. 



Hab : Bundaberg, Queensland, bred from cane leaves con- 

 taining leaf-hopper eggs, but I do not feel sure that it is para- 

 sitic on these. 



Alia grits, Hal. 



Ocelli in a subec|uilateral triangle, and close together, the 

 posterior very remote from the eyes ; antennae of female y-joint- 

 ed, scape long, second joint widened, third very short, the fourth 

 and following et|ual, club about equal to two preceding. An- 

 tennae of male filiform 13-jointed, second joint dilated, third also 

 wide on its flat face and short, much shorter than the following, 

 all the other joints subequal. Axillae produced forwards into
