HYMENOPTERA 85 



rugoso ; abdominis segmento primo pernigro, nitido, subtilissime ruguloso ; alis sub- 

 hyalinis. ?. Long. 6 mm. 



This species is extremely like several of the preceding, but without doubt distinct. 

 The mesothora.x and scutellum are quite dull, smooth except for the very fine rugulosity 

 of their surface, clothed with short pubescence, and finely and evenly punctured ; the 

 mesopleurae are not at all strigose or rough but are finely punctured. The basal 

 segment of the abdomen is deep, black and shining ; the apical segments clothed 

 with dark pubescence. 



Hab. Olaa, Hawaii (2000 ft.); a rare species. I took only two or three 

 specimens, and have not seen the </. 



(12) Nesoprosopis koat\ sp. nov. 



? nigra, praecedenti simillima, capite supra antennas minus opaco, et distinctius 

 punctato ; thorace minus opaco ; alis infuscatis, ad apices subcaeruleo-iridescentibus, 

 facile distinguenda. ?. Long, circa 6 mm. 



This is a very distinct species ; the thoracic puncturation appears to be identical 

 with that of the preceding, but the head above the antennae is less dull, and more 

 distinctly punctured ; the mesothorax less dull, and the scutellum somewhat shining. 



The wings are entirely infuscate, with distinct bluish iridescence on their apical 

 portion in certain lights. The longitudinal rugosity of the propodeum is unusually 

 short. The basal segment of the abdomen deep black, and shining, as in the pre- 

 ceding, and the apical segments clothed with black hairs. 



Hab. Mountains near Honolulu, Oahu (above 2000 ft.). A single specimen was 

 taken in 1892. In March, 1897, three more females were taken from the blossoms of 

 Acacia koa. 



(13) Nesoprosopis connectens, sp. nov. 



i niger, clypeo macula flava magna ornato, capite brevi, trans oculos lato, lamina 

 supraclypeari latiore quam longiore ; antennarum articulo primo haud fortiter dilatato ; 

 alis infuscatis ; segment! 8' ventralis parte producta minus fortiter dilatata, apice 

 bifurcato et ciliato. i. Long. 6 mm. 



Male, black, the clypeus with a large yellow spot, the front tibiae yellow inwardly. 

 Face short and wide across the eyes, the apical margin of the plate above the clypeus 

 much longer than its side to the antennal fossa. Antennae with the scape about 

 twice as long as wide, and strongly arched beneath. Head above the antennae 

 finely rugulose, dull, and very shallowly punctured. Mesothorax and scutellum finely
