83. Sierola megalops n.sp. 
2 shining black, the head dull; legs and antenne basally light yellow- 
ish brown, the latter outwardly fuscous, mandibles reddish apically. 
Head and thorax to the propodeum with a microscopically fine reticu- 
late surface sculpture, coarser on the head; finely, shallowly and fairly close- 
ly punctate, hairy clothing short and inconspicuous. Head a little longer than 
wide, widest across the eyes, narrowing in front and behind, width between 
the eyes nearly twice the length from eye to vertex; flatly convex above, 
depressed in front, tumid beneath, the greatest depth beneath the posterior 
end of the eye; vertical margin slightly convex, temples rounded, eyes con- 
vex; antennz reaching the mesoscutum, all the segments considerably longer 
than wide, antennal fosse deep; clypeus carinate, apically depressed and 
projecting slightly in front of the anterior margin of the head, declivous at 
the sides, the carina extending backward on the top of the head beyond the 
base of the antennze: mandibles slender, curved, truncate apically and toothed, 
base not quite reaching the eye; gula and sides of the head flatly convex, 
the former medially foreshortened, wider than long, anterior margin straight, 
posterior margin incised; propodeum finely rugulose; abdomen ovate, smooth 
and shining: wings hyaline; length 2.75 mms.
