34. Sierola pilosa n.sp. 



Plate XVI, Figure «. 



$ unusually large and thick-set ; dull shining black, antennse and legs 

 brown, the fore-femora outwardly and the antennae distally fuscous. 



Head and thorax to the propodeum with a microscopically close and 

 rather coarse reticulate surface sculpture, uniformly close!}' 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 ; antennae longer than the head, all the segments considerably longer 

 than wide, antennal foss;e 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 antennae ; 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. 1910.

35. Sierola inegaloi^iiafha n.sp. 



9 moderately fiat and unusually large: shining black, legs and antennae 

 brown to fuscous. 



Head and thorax with a microscopically fine reticvdate 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 ej'es, the greatest depth 

 less than half the length ; vertical margin straight, temples rounded, eyes 

 flatly convex ; antennae reaching the mesoscutum, segments of the flagellum 

 a little longer than wide, the pedicel nearly twice as long as wide, antennal 

 fossae 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 scarceh' as long as wide but not much 

 foreshortened medially, posterior margin incised, anterior margin arcuately 

 concave ; abdomen ovate, apicalh' acuminate, smooth and polished; wings 

 hyaline ; length 3.5 mms. 



$ smaller : mandibles yellowish brown, abdomen bluntly pointed at the 

 apex. 



Described from two females and one male (tvpe, allotype and paratvpe),
