loo FAUNA HAWAIIENSIS 



{ii) Nesoprosopis finithmx, sp. nov. 



N. longicipiti cognata, eodem colore et magnitudine sed mesonoto et scutello 

 subtilius punctatis ; ? capite etiam minus elongato, et pro longitudine latiore dis- 

 tinguenda. Long. 7 mm. 



(/ with the face shaped and coloured as in N. longiceps, but with the puncturation 

 of the mesothorax and scutellum distinctly finer ; the ? is more distinct, the difference 

 between the puncturation of its mesothorax and scutellum and that of longiceps being 

 more evident, and its head is evidently shorter and wider. 



Hab. Kauai, on the coast at Makaweli in 1894; a single pair only taken. It 

 must be a very scarce species in this and other localities where I searched for it, 

 as I was never able to take another specimen.

(Plate II. fig. 17 — 17 d.) 



Male, with the clypeus, the plate above it and a spot on each side of it yellow, the 

 greater part of the face in front of the antennae being of this colour ; front of the 

 anterior tibiae more or less flavous ; legs black, with the tarsi sometimes piceous or 

 testaceous. Head elongate, longer than its width across the eyes, above the antennae 

 dull, rugulose, and shallowly punctured, without any excessively finely and densely 

 punctured area, clothed with short inconspicuous pubescence ; scape of the antennae 

 dilated, strongly rounded on its posterior margin, little or not at all on the anterior, 

 evidently but not greatly longer than its greatest width, the front margin viewed 

 from in front deeply arcuate beneath. Thorax and scutellum dull, evenly and closely 

 punctured ; propodeum with its anterior area rugose, sometimes rather regularly 

 longitudinally, sometimes quite irregularly, the rugosities much stronger in some 

 individuals than others ; seen from in front the rugosities extend to the brow, which is 

 not at all smooth or shining. Abdomen dull, the intermediate ventral segments often 

 raised transversely across the middle ; when strongly raised, then generally the surface 

 is smoother and more shining, but extremely variable in this respect ; process of the 

 eighth ventral segment not much dilated dorso-ventrally, the apex bifurcate and 

 fringed with long hairs. 



Female, black, with only the flagellum of the antennae beneath, and the front of 

 the anterior tibiae pale. It closely resembles the c/ in form and sculpture; the clypeus
