HYMENOPTERA 673 



C. debilis var. subdcbilis van nov. 



Antennae paler than in typical debits (var. shnilis being intermediate), scutellar 

 cup decidedly narrower than in either of the above forms, about 2\ times as long 

 as wide, shining and nearly smooth on its sides, or at least hardly visibly sculptured 

 even under a very strong lens. 



Hab. Hawaii ; Kilauea. Without a long series of examples the three forms 

 described can hardly be considered as species. 



(9) Cothonaspis {H.) abnormis, sp. nov. 



Black, polished, two basal antennal joints, mandibles and all the legs ferruginous 

 or testaceous. 



Antennae long and slender, as long as the whole insect, the flagellum feebly 

 subclavate, the apical joints being evidently wider, when compared with the basal joints, 

 but all are elongate, the antepenultimate joint being about three times as long as wide. 

 Three basal joints almost of equal length, though the basal one, on actual measurement 

 is a trifle shorter. Scutellar cup elongate, not distinctly margined, and best seen when 

 looked at obliquely from in front. It is of narrow ellipsoidal form and very little raised, 

 the sides being extremely low, rugosely sculptured, and there is no posterior fovea ; 

 propodeum bicarinate, dull and hardly perceptibly sculptured between the carinae, 

 pubescent at the sides ; pleura smooth, the mesopleura with an impression. Wings 

 more or less yellowish-tinged, marginal cell closed above on about the basal half, 

 neuration brownish yellow, cubitus rather distinct. Abdomen strongly compressed, 

 with complete hairy girdle, the hypopygium prominent. Length 1-5 — 175 mm. $. 



Hab. Oahu ; 1500 — 2000 ft. 



Obs. This species might be placed in a distinct genus, but the possibility of the 

 occurrence in the islands of others, which would connect it with more usual forms, 

 renders it inadvisable to separate it generically at present. 



(10) Cothonaspis {H.) dubiosa, sp. nov. 



Black, polished, two basal joints of antennae and mandibles distinctly red, legs 

 flavo-testaceous, abdomen blackish or very dark brown over most of the basal portion, 

 becoming reddish apically, as also widely so at the sides beneath. Front and middle 

 tarsi brownish, the posterior tarsi dark fuscous. 



Antennae about two-thirds the length of the insect, the flagellum subclavate, fluted, 

 its third joint being evidently wider than the second, the latter and the first almost 

 equal in length, the third and fourth very slightly longer, the antepenultimate joint 

 twice as wide as long, the third rather longer, about 2^ times its width and evidently 

 fluted. Scutellar cup elongate, twice as long as its greatest width, very distinctly
