HYMENOPTERA 93 



very close ; propodeum with very short rugosities at its anterior margin, behind these 

 the surface finely rugulose, and about the brow in certain aspects quite brightly 

 shining, as also beyond it ; apical segments of the abdomen with blackish hairs. 



Hab. Hawaii from 2000 — 4000 ft. Taken in the heart of dense damp forests 

 in places where a little sunlight penetrates, and may also be found at the edges of 

 such forests. I have examined many examples. It is quite a distinct species, though 

 the cT is very variable in colour. 



(23) Nesoprosopis niutata, sp. nov. 



Praecedenti magnitudine forma et colore simillima, ^ capite supra antennas 

 minus distincte punctato, et plaga pernigra carente, scutello vix opaco, segment! 8' 

 ventralis parte producta haud dilatata, antennarum articuli basalis margine antico 

 subtus distincte arcuato ; ? scutello laeviore et nitido, tibiis posticis haud flavo- 

 notatis bene distincta. Long. 5-5 mm. 



This species represents on Kauai the A'^. dumeforum of Hawaii but is quite 

 distinct. The head is similarly formed, but above the antennae the surface is rougher 

 and the puncturation less distinct, and the c/ lacks entirely the deep-black mark so 

 conspicuous in the preceding ; the scutellum of the </ is decidedly less dull, of the ? 

 even shining ; the eighth ventral segment has the process of a quite different form, 

 not being dilated dorso-ventrally, nor evidently bifurcate at its apex. 



The two males taken have the facial markings as in N. diimetoruni, the tubercles, 

 prothorax and legs black, as in some varieties of that species ; the single ? has the 

 tegulae unspotted as in some examples of diimetoruni, and the base of both posterior 

 and intermediate tibiae also dark. 



Hab. Kauai (3000 ft.) ; 2 c/, i ? in a dense forest, flying over ferns in a sunny 

 spot. 



(24) Nesoprosopis specular is, sp. nov. 



? nigra, praecedentibus simillima ; capite supra antennas minus subtiliter punc- 

 tato ; spatio verticis, inter ocellum exteriorem et oculum sito, laevissimo nitidoque, ne 

 minime quidem ruguloso ; clypei apice flavo-lineata, distinguenda. Long. 5'25 mm. 



Female, like the preceding in size and general appearance, but the following 

 characters will readily distinguish it. The head above the antennae is exceedingly 

 closely and, for the size of the insect, rather strongly punctured : the surface between 

 the punctures is smooth and shining ; the spaces connecting the exterior ocelli with 

 the impressed longitudinal lines bordering the eyes are extremely smooth and shining.
