143. Sierola aucta u.sp. 
Plate XVI, Figure 7. 
@ unusually large and thickset; dull shining black, antennz fuscous, 
trochanters, tibia and tarsi yellowish brown. 
Head and thorax to the propodeum with a microscopically fine reticu- 
late surface sculpture: finely, shallowly and fairly closely punctate; hairy 
clothing short and inconspicuous. Head wider than the thorax, longer than 
wide by more than a half, width between the eyes not much greater than the 
length from eye to vertex, which is considerably more than the length in 
front of the eyes; flatly convex above, a little tumid beneath; vertical mar- 
gin slightly concave, temples rounded, eyes flatly convex; antennz reaching 
the mesoscutum, all the segments considerably longer than wide, antennal 
fosse deep; clypeus nearly flat, indistinctly carinate, hardly projecting in 
front of the anterior margin of the head, sloping at the sides; mandibles 
stout, curved, concavo-convex, somewhat flattened outwardly, truncate api- 
eally and toothed, base not reaching the eye; gula and sides of the head con- 
vex, the former not much foreshortened, as long as wide, anterior margin 
nearly straight, deeply notched at the sides by the base of the mandibles, 
posterior margin incised; propodeum finely rugulose; abdomen short ovate, 
apically acuminate, smooth and polished; wings with a yellowish brown 
pigmentation; length 4 mms. 
Described from twe females (type and paratype). Type (numbered 11) 
from Puuwaawaa, N. Kona, 3800 ft. elevation, collected by W. M. Giffard,

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, tumid beneath, the greatest depth beneath the pos- 
‘terior end of the eye; vertical margin straight, temples rounded, eyes convex ; 
antenna reaching the mesoscutum, all the segments considerably longer than 
wide, antennal fossze deep; clypeus carinate, apically depressed, hardly pro- 
jecting in front of the anterior margin of the head, sloping at the sides, the 
carina extending backward on the top of the head beyond the base of the 
antennz; mandibles stout, curved, concavo-convex, truncate apically and 
toothed, base not quite reaching the eye; gula flatly convex, medially fore- 
shortened, width twice the length, median furrow nearly effaced, anterior 
margin arcuately concave, deeply notched at the sides by the base of the
