90 FAUNA HAWAIIENSIS 



(19) Nesoprosopis kauaiensis, sp. nov. 



Forma fere praecedentium, N. unicae cognatissima ; alis subhyalinis ; t/ clypeo, et 

 duabus extra clypeum maculis, pallide flavis ; pronoto postice interrupte flavo-lineato ; 

 ? lineis duabus juxta oculos flavis, margine postico pronoti ad latera flavo-lineato. 

 </?. Long. 6 — 7 mm. 



Male, with the scape of the antennae and the form of the head much as in the 

 preceding species ; clypeus almost entirely, a spot on each side of the face outside 

 the clypeus, and the hind margin of the prothorax at the sides, very pale yellow ; 

 the posterior edge of the clypeus strongly rounded ; head with long dark pubescence. 

 Mesothorax dull, and closely punctured, densely clothed with black pubescence ; 

 scutellum closely and evenly punctured ; propodeum with the anterior area longitu- 

 dinally rugose in front, the rugosities short, not reaching the brow ; posterior tibiae 

 and tarsi normally dark, sometimes, when the abdomen is of a more or less reddish 

 immature colour, they are more or less pale ; 8th ventral segment of the abdomen 

 much as in the allied species. 



Female, in general sculpture and form like the cT ; two spots on the prothorax, 

 and a line on each side of the face near the eyes, pale yellow ; mesothorax and 

 scutellum quite dull, evenly and closely punctured ; propodeum with a few longitudinal 

 wrinkles of moderate length, not reaching the brow ; basal segment of the abdomen 

 shining and very smooth ; apical segments with dark hairs. 



Hab. Mountains of Kauai (3000 — 4000 ft.) ; taken on several occasions, but 

 scarce. The large pale markings of the face in the </, and the spotted collar and 

 clear wings in both sexes, give this little species a very distinct appearance. 



(20) Nesoprosopis comes, sp. nov. 



Nigra, capite longitudinaliter minus fortiter convexo ; mesonoto opaco, subtiliter 

 minus dense punctato, pilis fuscis longioribus vestito ; scutello haud nitido, minus 

 dense subirregulariter punctato ; propodei area antica subtiliter irregulariter rugosa ; 

 alis plus minusve infuscatis ; </ clypei apice flavo-maculato ; antennarum articulo primo 

 dilatato, longiore quam latiore, subtus modice arcuato; segmenti 8' ventralis produc- 

 tione fortiter dilatata. cT ? . Long. 6 mm. 



Black, the d" with a spot of variable size (which would probably be sometimes 

 absent) on the clypeus near its apex ; front of the front tibiae pale, as is usual in 

 this sex of most species. Male with the face short, but not of the great width 

 of the several preceding species, nor nearly so convex longitudinally ; plate above
