82 New Species of Sierola, With Explanatory Notes. 
Head and thorax to the propodeum with a microscopically fine retic- 
ulate surface sculpture, finely, shallowly and remotely punctate, hairy cloth- 
ing short and inconspicuous. Head longer than wide, length from eye to 
vertex equalling the width between the eyes; convex above, depressed in 
front, tumid beneath, greatest depth behind the eyes, vertical margin 
straight, temples rounded, eyes flatly convex; antenne reaching the meso- 
scutum, segments of the flagellum scarcely longer than wide, pedicel about 
twice as long as wide, antennal fosse somewhat shallow; clypeus short, 
flat on top, apically depressed and blunt, hardly exceeding the anterior 
margin of the head, basally marked by converging lines from the sides; 
mandibles fairly stout, bent at the middle, distal portion flattened, truncate 
apically and toothed, base not reaching the eye; cheeks narrow; gula and 
sides of the head flat, the former medially foreshortened, longer than wide, 
narrowing behind, both anterior and posterior margin rather deeply incised; 
propodeum rugulose; abdomen somewhat particolored, elongate ovate, smooth 
and polished; wings subinfuscate; length 2.75 mms. 
Described from two females (type and paratype). Type collected at 
Opaeula, Oahu, by D. T. Fullaway, March 30, 1913. Paratype collected on 
Mt. Kaala, Oahu, by P. H. Timberlake, July 22, 10917. 
Type: Cat. No. 21, Bishop Museum. 
22. Sierola aristoteliae n.sp. 
@ black, with the exception of the prothorax, which is yellowish brown, 
thorax only faintly shining, the head dull, opaque or nearly so; legs, apex of 
the clypeus, antenne basally and the mandibles, except at the base, luteous, 
antenne fuscous outwardly. 
Thorax with a microscopically fine reticulate surface sculpture, head 
coarsely sculptured, apparently minutely granulate; very finely and closely 
punctate; clothed with a rather dense covering of short procumbent hairs. 
Head a little longer than wide, width between the eyes greater than the 
length from eye to vertex; length in front of the eyes not great; convex 
above, depressed in front, tumid beneath, the greatest depth in front of the 
posterior end of the eye; vertical margin straight, temples rounded; eyes 
convex, antennze longer than the head, segments of the flagellum scarcely 
longer than wide, pedicel nearly twice as long as wide, antennal fosse deep; 
clypeus short, projecting a litttle from the anterior margin of the head, longi- 
tudinally elevate in the middle and sloping at the sides, apex depressed, the 
carina distinct behind the antennz but effaced in front of it; mandibles stout, 
curved, concavo-convex, truncate and toothed apically, base touching the eye 
above; gula and sides of the head convex, the former not much foreshort- 
ened medially, longer than wide, anterior margin arcuately concave, poste- 
rior margin incised; abdomen short ovate, smooth and polished; wings hya- 
line; length 2.5 mms. 
Described from seven females (type and paratypes), four, including the 
type reared from the larve of a species of Aristotelia infesting a Gouldia 
fruit collected in Palolo by O. H. Swezey, January 11, 1914. Of the remain- 
ing paratypes, one was collected on Manoa Cliffs by P. H. Timberlake, 
March 29, 1918; one in the S. E. Koolau Mountains by J. C. Bridwell, Sep-
