lo FAUNA HAWAIIENSIS 



developed. Apical dorsal segment of the abdomen carinated at the sides, punctured, 

 clothed with appressed hairs, which give it a strigose appearance. 



Hab. Kauai (2500 — 4000 ft.); common, burrowing in the hard ground in bare 

 spots in the forest. 



(2) Nesominiesa sciopteryx, sp. nov. 



Praecedentis forma ; alis totis piceis, clypeo subtiliter griseo-pubescente distinc- 

 tissima. ?. Long. 1 1 mm. 



Female very like that of the preceding in form. The wings are entirely of a 

 pitchy colour, and have a slight violet iridescence. The face below the antennae 

 is clothed with a fine greyish pubescence, instead of the appressed silvery pilosity 

 of all the other Hawaiian species. The posterior calcaria are testaceous, and the 

 petiole of the abdomen is stouter, and its dorsal surface more strongly curved. 



Hab. Halemanu, Kauai (4000 ft.) ; very rare, i ? only taken. 



(3) Nesomintesa antennata. 



Miniesa antennata, Smith, Cat. Hym. Ins. iv. p. 431. 



N. kauaiensi simillima ; % spina genali ad basim contorta, </ clypei margine 

 apicali haud evidenter tridentato distinguendus. cT tarsis anticis testaceis, ? propodei 

 area antica haud nitida, tarsorum spinis anticorum pallidis. d*?- 7 — ^3 rn^n- 



Very like N. kauaiensis, but generally the ? is less robust and has the head 

 smaller. It may be at once distinguished by the form of the spine on the cheek, 

 which, instead of continuing the outline of the face behind the eyes, is raised at 

 the base, and somewhat twisted, so that, in a lateral view of the head, the spine 

 presents a sharp edge. The apical margin of the clypeus is produced into a small 

 median tooth. In well-developed examples the facial spines are very long, more or 

 less pointed at the apex, and their margins sinuate. The mesothorax is somewhat 

 shining, the scutellum distinctly so, the anterior area of the propodeum very dull, as 

 compared with the scutellum. The wings are sometimes more or less clouded, often 

 almost entirely clear. The spines of the anterior tarsi are pale. 



The cT differs from that of N. katiaietisis only in the shape of the anterior 

 margin of the clypeus, which is not evidently tridentate, although somewhat produced 

 in the middle. 



Hab. Mountains of Oahu (2000 ft. and upwards).
