New Species of Sierola, With Explanatory Notes. 89 
34. Sierola pilosa u.sp. 
Plate XVI, Figure 6. 
2 unusually large and thick-set; dull shining black, antennz and legs 
brown, the fore-femora outwardly and the antenne distally fuscous. 
Head and thorax to the propodeum with a microscopically close and 
rather coarse reticulate surface sculpture, uniformly closely and shallowly 
punctate and clothed with long light brown to silvery hairs. Head con- 
siderably longer than wide, widest across the eyes, much narrower behind 
and in front, width between the eyes a little more than the length from the 
eye to the vertex, which is considerable; flatly convex above, depressed in 
front, very tumid beneath; vertical margin straight, temples rounded, eyes 
convex; antennz longer than the head, all the segments considerably longer 
than wide, antennal fossze deep; clypeus reduced to an extremely thin, cari- 
nate ridge, vertically depressed apically and projecting a little in front of 
the anterior margin of the head, the carina extending backward on the top 
of the head beyond the base of the antenne; mandibles slender, curved, 
apically toothed, base not reaching the eye; cheeks narrow; gula and sides 
of the head flat, the former medially foreshortened, as wide as long in front, 
narrowing behind where it is strongly protuberant and divided into two lobes 
by a deep sulcus; anterior margin almost straight; propodeum rugulose ; 
abdomen elongate ovate, mostly smooth and polished, but an extremely fine 
reticulate surface sculpture evident; wings subinfuscate, with a faint yellow- 
ish-brown pigmentation: length 3.5 mms. 
Described from five females (type and paratypes), collected at Kuala- 
puu, Molokai, by D. T. Fullaway, July 15, rgto. 
Type: Cat. No. 34, Bishop Museum. 
35. Sicrola megalognatha n.sp. 
@ moderately flat and unusually large; shining black, legs and antenne 
brown to fuscous. 
Head and thorax with a microscopically fine reticulate surface sculp- 
ture, closely and shallowly punctate and hairy. Head nearly as wide as 
long, widest at the vertex, narrowing a little in front, width between the 
eyes nearly twice the length from eye to vertex; flat on top, depressed in 
front, a little tumid beneath; deepest behind the eyes, the greatest depth 
less than half the length; vertical margin straight, temples rounded, eyes 
flatly convex; antennze reaching the mesoscutum, segments of the flagellum 
a little longer than wide, the pedicel nearly twice as long as wide, antennal 
fosse deep; clypeus carinate, apically depressed and projecting a little in 
front of the anterior margin of the head, sloping at the sides; mandibles 
abnormally large, bent at the middle, the distal portion flattened and punc- 
tate, apically truncate and toothed, base reaching the eye above; gula and 
sides of the head flat, the former scarcely as long as wide but not much 
foreshortened medially, posterior margin incised, anterior margin arcuately 
concave; abdomen ovate, apically acuminate, smooth and polished; wings 
hyaline; length 3.5 mms. 
4 smaller; mandibles yellowish brown, abdomen bluntly pointed at the 
apex. 
Described from two females and one male (type, allotype and paratype),
