86 FAUNA HAIVAIIENSIS 



punctured, dull, the pubescence of the former short. Propodeum longitudinally rugose 

 in front. Wings rather strongly infuscate, and with a slight blue iridescence. The 

 process of the 8th ventral segment of the abdomen is evidently but not at all strongly 

 dilated, its apical bifurcation more strongly so, and ciliated with long hairs. 



Hab. a single d" was taken in the lao valley, Maui. A female captured with it 

 is evidently of the same species, and is very closely allied to A^. koae, but this example 

 is much mutilated. A single ? taken on Lanai is also extremely close to, if not 

 identical with, one of these species. 



(14) N^esopi'osopis melanotJirix, sp. nov. 



Nigra, capite, thorace et abdominis segmentis apicalibus densius nigro-pubes- 

 centibus ; propodei rugis longitudinalibus antice brevissimis, vel absentibus ; mesonoto 

 et scutello subaequaliter punctatis ; alls infuscatis caeruleo-iridescentibus ; c/" capite 

 prae antennis toto nigro, aut maculis tribus flavis ornato ; antennarum articulo 1° 

 fortissime arcuato, scutello opaco ; ? scutello nitido, clypei apice distincte angulatim 

 emarginato. c/?. Long. 6 — 8 mm. (Plate II. figs. 14 — 14^.) 



Male, entirely black, except the testaceous front of the fore tibiae, or with the 

 clypeus, and a spot on each side bordering the eyes, yellow, or with the latter markings 

 only present ; the clypeus is more or less emarginate at the apex, clothed with dark, 

 and rather long, erect hairs, somewhat largely but shallowly punctured, the plate 

 above it is similarly punctured, generally much wider than long, but variable in this 

 respect ; head above the antennae, and the vertex, with very long dark hairs, densely 

 and rugosely punctured, and dull ; antennae with the scape dilated, its posterior 

 margin rounded but not strongly, the dilated surface evidently not twice as long as 

 wide ; beneath exceedingly strongly arched, so that when the anterior margin is 

 viewed from in front the apex appears to be strongly produced, both base and apex 

 being much thickened owing to the deep concavity of the part between. Mesothorax 

 with long erect black hairs, shallowly and rather closely punctured, its surface dull 

 and rugulose between the punctures ; scutellum similarly clothed and dull, the punctures 

 rather larger than those of the mesothorax ; propodeum with very short ill-defined 

 longitudinal rugosity in front, sometimes obsolete : behind this the surface finely 

 rugulose, its sides clothed with pubescence of an obscure colour ; wings infuscate, 

 with blue iridescence ; thorax beneath, and the legs with dark pubescence. Abdomen 

 very finely rugulose, and hardly shining ; beneath, shallowly punctured ; 6th segment 

 with the apex emarginate, and carinated behind the emargination ; 8th with the 

 process strongly dilated dorso-ventrally, the ventral edge densely hairy, its apex 

 bifurcate, the bifurcations expanded, fringed with long hairs along their ventral 

 margins.
