674 FAUNA HAWAIIENSIS 



marked by its pale margins throughout, a few scattered punctures (in the type specimen) 

 in front of the posterior fovea ; sides of the cup somewhat shining, with some very fine 

 punctures, and extremely fine longitudinal rugulosity, sparsely pilose ; pleura smooth 

 and polished ; propodeum with the two longitudinal carinae as in the other species. 

 Wings ciliate, the neuration yellowish at base, becoming darker apically, the apical 

 side of the marginal cell being- dark fuscous ; this cell closed on its basal half above. 

 Length rather more than 2 mm. $. 



I cannot be sure that the marginal cell in this species is not altogether closed, as 

 in some aspects the nervure on the upper side of the cell appears continuous to the 

 apex, though fainter beyond the middle. 



Hab. Oahu ; 1500 ft. I have only examined one e.xample and the abdomen is 

 partly crushed. 



(11) Cothonaspis {H.) dichroina, sp. nov. 



Black, polished, the two basal joints of the antennae distinctly red, as well as the 

 mandibles, legs testaceous, the tarsi more or less infuscate, the hind ones dark fuscous 

 or blackish above, abdomen ferruginous. 



Antennae rather more than two-thirds the length of the whole insect, the flagellum 

 subclavate, its second joint being considerably less wide than the third, its first joint 

 more slender still ; the first of these joints very little longer than the second, and all the 

 flagellar joints are elongate, submoniliform, the antepenultimate (with its contracted 

 base) being about twice as long as wide. Scutellar cup elongate, rather more than 

 twice as long as wide, pointed anteriorly and foveated at the other e.xtremity, one or 

 two fine punctures inside either margin ; at the sides it is densely rugosely sculptured 

 or rugose-punctate and sparsely pilose. Propodeum between the carinae impressed, 

 slightly hairy, hardly sculptured. Pleura smooth, not sculptured. Hypopygium some- 

 what exserted. Length 2 mm. %. 



Hab. Oahu, about 1500 ft. 



EucoiLA Westw. 

 ( I ) Eucoila {Psichacra) oreias, sp. nov. 



Black, smooth and shining, mandibles red on their apical part, coxae black or very 

 dark ; front and middle femora mostly dark brown above, the apical part being pale 

 brownish yellow, front and middle tibiae yellowish brown, the latter sometimes darker 

 than the former ; hind legs darker than the others, the femora black or nearly, excepting 

 the yellowish apices, tibiae dark brown except at base, the tarsi entirely blackish or 

 dark fuscous. Neuration yellowish, the apical side of the marginal cell paler than most 

 of the neuration. 



Antennae as long as the entire insect, or almost so, the first two joints beyond the 

 pedicel being somewhat thinner than the next. The flagellar joints are subequal in
