678 FAUNA HAWAIIENSIS 



Enicospilus kaalae Ashm. 



Enicospilus semiriifus Perkins, Tr. Ent. Soc. London, 1902, p. 142. 



My E. semirufus is a variety of the above. I characterized it as distinct from 

 the fact that the male of E. kaalae was said to resemble the female. In the type, 

 however, the male of E, kaalae lacks the distinct carina of the female. The colour 

 description likewise did not altogether agree. The examination of a large number of 

 examples shows that the carina on the propodeum of E. kaalae may be present or absent 

 and is not a specific character. 



Hab. Oahu ; very common throughout the island. The type is from Kauai. 



( I ) Enicospilus tyrannus, sp. nov. 



Male, head and face yellow, the ocelli very large, dark brown ; the mandibles and 

 mouth-parts brownish, the impressions on each side of the clypeus and a median spot 

 beneath the antennae brown. Antennae ferruginous or testaceous, towards the apex 

 fuscous. Pronotum mostly yellowish, the mesonotum dark brown, bordered with 

 yellowish, and with a yellow longitudinal line on each side of the middle, dividing the 

 dark colour into an anterior and two postero-lateral lobes ; scutellum and postscutellum 

 brown medially, more yellow laterally, propodeum blackish pitchy ; more brown on the 

 smooth anterior area. Legs ferruginous, the tibiae and tarsi paler. Abdomen dark 

 brown or dark fuscous, in parts more reddish brown, especially in lateral aspect. 



Female with the inner orbits widely pale yellow below the antennae, narrowly so 

 above ; middle of the face brown, the clypeus more yellowish, palpi and mandibles 

 testaceous or ferruginous, the latter with dark teeth, occiput mostly pale yellow. 

 Pronotum dark brown with a yellow area on each side, mesonotum blackish fuscous, the 

 lateral margins in front and a space in the middle posteriorly, yellowish or reddish ; 

 scutellum at sides yellow, more testaceous above ; propodeum black. Legs with the 

 coxae black or very dark brown, the femora brown, tibiae and tarsi ferruginous. 

 Abdomen dark blackish fuscous, a little red-tinged in parts. 



Antennae of male extending well beyond the apex of the spread wings, in the 

 female reaching about to the apex, the eyes very large, leaving only a very short cheek 

 between the eyes and mandibles. Mesonotum dull, with very fine and dense rugulose 

 puncturation, more pubescent in the female ; propodeum nearly smooth and somewhat 

 shining in front in the male, and at the most with faint traces of a carina dividing off the 

 posterior finely rugose portion ; in the female the carina is distinct, the part in front of it 

 finely and densely rugose, but less dull and more finely sculptured than the posterior 

 portion. Wings distinctly yellowish-tinged in the male, still more conspicuously so in 

 the female ; stigma of male brown, of female dark brown, discocubital cell with two 

 distinct yellowish spots, the basal larger and of triangular shape. Length ^ 1 7, 

 $ 22 mm.
