HYMENOPTERA 89 



antice rugosa ; capite supra antennas in media parte sublrregulariter punctato. </ ? . 

 Long. 6 — 8 mm. (Plate II. figs. 15 — 15 (5.) 



Male, face entirely black, or with two yellow spots, one on each side between 

 the eye and clypeus ; face transverse, the plate above the clypeus very broad, twice 

 as wide as high ; head above the antennae punctured, and clothed with obscure 

 pubescence, as also the thorax ; mesothorax dull, very finely punctured, scutellum 

 somewhat more largely but not very closely ; anterior area of the propodeum 

 generally with some short rather strong longitudinal wrinkles at the extreme front. 

 In some examples these are longer than in others and less regular, but they do not 

 reach the posterior margin of the area, which has only the usual rugulose sculpture 

 of the surface. Front legs pale in front, tarsi generally more or less testaceous ; 

 wings entirely fuscous with more or less blue iridescence ; 8th ventral segment of 

 the abdomen with the process dilated, as also its apical bifurcations. 



Female, very like the male apart from sexual characters ; head very wide and 

 strongly convex, above the antennae very finely strigose and finely punctured, the 

 punctures rather remote towards the middle ; mesothorax and scutellum dull, clothed 

 and punctured, as in the </ ; propodeum with the anterior area smooth, except 

 for the rugulosity of its surface, and some extremely short wrinkles at the front 

 margin, sometimes obsolete ; wings as in the t/, legs dark, apical segments with 

 black hairs. 



Hab. Dense wet forests high up on the mountains of Molokai, (above 4000 ft.). 

 Not common, flying rapidly over ferns in places where the sunlight can penetrate the 

 brush. On Lanai (2000 — 3000 ft.) the species is found of considerably smaller average 

 size but (so far as I can see) inseparable from the Molokai examples by any constant 

 character. The localities where it is found on Lanai are much less wet, and less 

 heavily timbered, than those on Molokai, but appear to have been of much the same 

 character before the forest had been so much thinned out and destroyed. 



(18) Nesoprosopis neglecta, sp. no v. 



Forma facieque praecedentis, capite supra antennas circa medium densissime 

 rugoso-punctato, propodei area antica irregulariter fere tota rugosa, bene distincta. 

 ? . Long. 7 mm. 



Of the same general form and appearance as the preceding but no doubt distinct. 

 The head above the antennae is very densely subrugosely punctured, and the pro- 

 podeum rather finely and irregularly rugose right up to the brow, whereas in N. 

 laticeps the rugosity is extremely short, and the brow itself slightly shining. 



Hab. Mountains of Molokai in the high boggy forest. Sept. 21st, 1893. i ? taken.
