662 FAUNA HAWAIIENSIS 



apex, its upper side curved, wlien seen in profile ; ovipositor exserted to about the length 

 of the claw joint of the hind tarsus. Wings with dark, ovate, punctiform marginal 

 vein ; the longest cilia hardly half as long as the greatest width of the front wing. 

 Length i"5 — 2 mm. 



Hab. Hawaii, 4000 ft. ; bred from shoots of Myrsine bored by the caterpillar of 

 a very large species of Archips (Tortricidae), but I cannot conjecture the true host of 

 this parasite. 



(2) Polynema ten-estris, sp. nov. 



Black, two basal antennal joints and all the legs yellow ; abdominal petiole yellow 

 or brownish yellow or in the Z partly dark brown, third antennal joint in the % more or 

 less pale. 



Antennae of $ very long and filiform, one and a half times as long as the whole 

 insect, the joints of the funicle elongate and about equal, the third being five times (or 

 more) as long as wide. First funicle joint in % hardly half as long as the second, which 

 is considerably longer than the third, the fourth, fifth and sixth subequal, the last about 

 three times as long as its greatest width, club rather longer than the two preceding. 

 Sculpture of the thorax, which is somewhat shining, of the usual kind, but hardly 

 visible under the strongest lenses ; front wings with dark, punctiform marginal vein, the 

 longest cilia hardly half as long as the greatest width of the wing. Ovipositor of % 

 very slightly exserted. Length r5 — 175 mm. 



Hab. Oahu, 1500 ft. and upwards. 



(3) Polynema pyrophila, sp. nov. 



Black, the second joint of the antennae beneath paler, more or less yellowish 

 or brown, in the <? sometimes obscurely pitchy ; coxae and trochanters generally more 

 or less brownish, tips of femora, except sometimes the hind ones, distinctly pale. 



Antennae of i with the pedicel roundish in lateral aspect, the first funicle joint 

 rather shorter than the second, the following joints subequal and more than three times 

 as long as wide. Antennae of ? very slender, the long ovate club rather longer than 

 the two preceding joints together, the pedicel dilated, the first funicle joint hardly half 

 as long as the second, which is about one and one-fifth longer than the third. Pronotum 

 short, mesonotum hardly shining, with excessively fine reticulate surface sculpture, 

 visible only under a very strong lens, the parapsidal furrows very distinct, the scutellum 

 elongate and large, divided by a fine transverse line about the middle ; the propodeum 

 and abdomen smooth and polished. Second abdominal segment much narrowed from 

 the apex forwards to its junction with the petiole. Ovipositor prominent, as lono-
