HYMENOPTERA 671 



largely foveated posteriorly, and with a series of distinct marginal piligerous punctures 

 on each side, from near the base to the fovea ; sides of scutellum below the disc 

 longitudinally wrinkled and pilose ; propodeum between the carinae very dull and 

 densely rugulose, at the sides with a patch of dense woolly hair ; mesopleura smooth, 

 metapleura longitudinally strigose. Wings hyaline, faintly yellow-tinged, ciliated ; 

 neuration for the most part rather pale yellowish brown, marginal cell open above, the 

 cubitus much fainter than the other nervures. Abdomen elongate-ovate pointed at apex, 

 with a dense basal girdle of yellowish pubescence, the hypopygium not conspicuously 

 exserted, but more so in some examples than in others. The basal flagellar joints of 

 the antennae are sometimes more or less reddish-tinged. Length 2 '25 mm. $. 



The antennae are so slender that they can hardly be called subclavate, and 

 possibly this species could be referred to Forster's genus Anectoclis. 



Hab. Oahu, near Honolulu, above 1500 ft. 



(5) Cothonaspis {H.) strigosa, sp. nov. 



Extremely similar to P. tantali, having the same scutellar structure, similar 

 antennae etc. It is readily distinguished, however, by the mesopleura posteriorly being 

 strongly longitudinally strigose, like the metapleura, instead of being altogether smooth 

 and shining. 



Hab. Oahu; Honolulu, above 1500ft. 



(6) Cothonaspis (//.) declivis, sp. nov. 



Black, the two basal antennal joints red, mandibles and legs testaceous or brownish 

 yellow. 



Antennae long, about as long as the whole insect, all the flagellar joints elongate, 

 the flagellum appearing subclavate, owing to the more apical joints being proportionately 

 rather wider and shorter than the more basal ones, in some aspects ; first and second 

 flagellar joints nearly equal in length, the latter slightly stouter, about equal to the 

 following, but rather more slender, third about three times as long as wide, the ante- 

 penultimate joint about twice as long as wide. Mesonotum polished, sparsely pilose, 

 pleural region smooth and polished, including the metapleura. Scutellar cup more than 

 twice as long as wide, very convex longitudinally and very strongly declivous posteriorly 

 before the large round fovea, also strongly convex transversely, sides of the cup 

 rugulose, but partly smooth ; propodeum dull between the carinae, but very indistinctly 

 sculptured. Wings ciliated, neuration brownish yellow, the marginal cell open above, 

 except for a short distance at base, cubitus very faint. Hypopygium not prominent. 

 Length 2 mm. %.
