line of insertion of the antennae, yellow ; the lateral triangles are always divided from 

 the yellow of the clypeus by more or less narrow black lines ; the plate above the 

 clypeus is entirely black. In form the species is very like N. obscurata, but the 

 following characters will easily distinguish it. Male with the scape of the antennae 

 evidently more strongly dilated, its posterior margin more strongly rounded ; punctura- 

 tion of the mesothorax and scutellum rather finer, these parts being very dull, with 

 very close and shallow punctures. The % may be known at once by the exceedingly 

 minute shallow puncturation of the mesothorax, that of the scutellum being only slightly 

 more distinct, and the surface of both quite dull. Wings more or less distinctly 

 clouded, especially across the middle portion. 



Hab. Mountains of Lanai (2000 ft.) and on the coast at Awalua. Wailuku, 

 Maui on the sandhills, and at Lahaina. Not common. 



Nesoprosopis assimulans var. oahue'nsis, var. nov. 



(/ maculis flavis minoribus, ? alis fortiter infuscatis distinguenda. 



Agrees with the former in structure, but the </ has the yellow markings of the 

 face often much reduced in size, and the wings generally darker ; ? with the wings 

 entirely infuscate, and in certain lights with a distinct steely iridescence. 



Hab. Waialua and Waianae (Oahu), on the coast, or a few hundred feet above 

 sea-level. 



(37) Nesoprosopis inquilina, sp. nov. 



Nigra, opaca, griseo-pubescens, alis hyalinis ; </ clypeo fere toto, maculisque duabus 

 triangularibus extra clypeum, late supra antennas productis, flavis ; lamina supra- 

 clypeari tota, vel ex majore parte, nigra ; antennarum articulo primo fortius dilatato, 

 apice antice producto ; ? capite nigro, trans oculos lato, mesonoto opaco, levissime 

 punctato ; tarsis anterioribus pilis brevioribus, vix curvatis, vestitis. Long. 7 mm. 



Male, with the clypeus almost entirely, and the sides of the face between it and 

 the eyes, yellow ; the latter markings produced rather widely above the antennae along 

 the margin of the eyes ; plate above the clypeus entirely or almost entirely black ; 

 anterior tibiae and tarsi pale in front ; tibiae of the intermediate and posterior legs 

 sometimes with a yellow spot at the extreme base, and slightly pale at the apex, their 

 tarsi black or piceous. 



Face much shorter and wider than that of A^. longiceps. the scape of the 

 antennae somewhat strongly dilated, and of peculiar form, as its anterior apical angle is 

 somewhat produced ; head above the antennae closely, subrugosely and very shallowly
