129. Siterola flavipes n.sp. 
@ shining black, the head, pronotum, mesoscutum posteriorly and the 
scutellum dull; legs and basal segments of the antenne flavous. 
Head and thorax with a microscopically fine and close reticulate surface 
sculpture, the mesoscutum anteriorly and the propodeum more delicately 
sculptured, the former nearly smooth; finely, closely and shallowly punctate ; 
clothed with long silvery white hairs. Head as wide as long, widest across 
the eyes, narrowing behind and in front, width between the eyes more than 
twice the length from eye to vertex; convex above, depressed in front, a little 
tumid beneath, the greatest depth beneath the eye; vertical margin straight, 
temples rounded, eyes flatly convex; antennz reaching the mesoscutum, all 
the segments longer than wide, the pedicel twice as long as wide, antennal 
fossee deep; clypeus carinate, apically depressed and projecting slightly in 
front of the anterior margin of the head, which is angulate, not transverse, 
declivous at the sides, the carina extending backward on the top of the head 
beyond the base of the antennze; mandibles fairly slender, curved, truncate 
apically and toothed, base reaching the eye above; gula and sides of the 
head flat, the former medially foreshortened, wider than long, narrowing 
behind, anterior margin nearly straight, posterior margin incised, a shallow 
sulcus posteriorly on the median line, the furrow nearly effaced in front ; 
abdomen elongate ovate, smooth and polished; wings subinfuscate, with a 
faint yellowish brown pigmentation; length 3 mms. 
Described from one female (type) collected on Tantalus Mountain, 
Oahu, elevation 1300 ft., by W. M. Giffard, April 4, 1905.

widest across the eyes, narrowing behind and in front, width between the 
eyes considerably more than the length from eye to vertex; convex above, 
depressed in front, a little tumid beneath; vertical margin straight, temples 
rounded, eyes flatly convex; antenne reaching the scutellum, all the seg- 
ments longer than wide, pedicel and first to third funicular segments twice 
as long as wide, antennal fossze deep; clypeus carinate, apically depressed 
and projecting slightly in front of the anterior margin of the head, which is 
angulate, not transverse, sloping at the sides, the carina extending backward 
shortly on the top of the head; mandibles slender, curved, truncate apically 
and toothed, base not quite reaching the eye; gula and sides of the head 
convex, the former not very much foreshortened medially, longer than wide, 
a slight depression along the median line posteriorly, the groove nearly 
effaced in front, anterior margin slightly concave, posterior margin incised; 
propodeum rugulose: abdomen ovate, apically acuminate, smooth and_pol- 
ished; wings subinfuscate, with a very faint yellowish brown pigmentation ; 
length 2.75 mms.
