6/2 FAUNA HAWAIIENSIS 



Note. With P. dcclivis and P. tantali I take a male Cynipid, which I cannot 

 refer to either with any certainty. It may be distinct from either, but I suspect this is 

 not the case. 



(7) Cothonaspis {H.) naias, sp. nov. 



Black, polished, five basal joints of the antennae red, mandibles and legs testaceous 

 or ferruginous, hind coxae browner, hind tarsi evidently infuscate. 



Antennae two-thirds the length of the whole insect, the basal joint of the flagellum 

 equal in length to the third, but evidently more slender, the second joint being much 

 shorter, about two-thirds the length of these, fourth and following joints wider than the 

 third, all elongate, submoniliform, subequal, the antepenultimate joint about twice as 

 long as wide. Scutellar cup long and narrow, acuminate in front, foveated at its 

 posterior end, about three times as long as wide, with several evident punctures on its 

 smooth surface, its sides distinctly, finely rugulose. Propodeum with a dense patch of 

 pubescence outside each of the longitudinal carinae ; meso- and metapleura smooth and 

 polished. Wings clear, hyaline, ciliated, marginal cell apparently closed above on less 

 than its basal half, neuration yellowish brown, cubitus faint. Hypopygium somewhat 

 prominent. Length 175 mm. $. 



Hab. Oahu ; 1 500 ft. 



(8) Cothonaspis {H.) debilis, sp. nov. 



Black, polished, mandibles and two basal antennal joints yellowish brown, some 

 other of the basal flagellar joints also more or less pale, legs testaceous, apices of tarsi 

 dark. 



Antennae as long as the whole insect, slender, but gradually subclavate, the two 

 basal flagellar joints being notably more slender than those towards the apex. First 

 flagellar joint subequal to or a trifle longer than the second, which is subequal to the 

 following joints ; fluted sculpture distinct ; antepenultimate joint of antennae twice as 

 long as wide. Scutellar cup elongate-ovate, twice as long as its greatest width, foveate 

 at its posterior end, and with a few fine punctures before the fovea ; sides very finely 

 rugulose ; propodeal carinae distinct, the pubescence not dense ; mesothoracic and 

 metathoracic pleura smooth, polished. Neuration brown, yellow-tinged, cubitus much 

 paler and fainter than radius, but easily seen, marginal cell closed above for only a short 

 distance at the base. Hairy girdle of abdomen not dense, hypopygium not strongly 

 prominent. Length hardly 1-5 mm. $. 



C. debilis van siniilis van nov. 



Very like the above in api^earance and structure, but the hind coxae are rather 

 darker brown, the scutellar cup is slightly wider, its margins more distinct and at the 

 sides it is shining and smooth instead of being rugulose.
