HYMEN OP TERA 1 1 3 



Female robust, but not very large ; head entirely red except the eyes, closely 

 and rugosely punctured above the antennae, the pubescence pale. Thorax black, 

 prothorax with a whitish posterior margin ; tegulae testaceous with a yellow spot ; 

 mesothorax excessively densely and shallowly punctured, the disc glabrous, but all 

 the margins clothed with pale fulvous pubescence, as also the whole of the scutellum, 

 postscutellum, and propodeum, except the anterior area of the latter, which is quile 

 hairless, and rather strongly clathrately-rugose and shining. Abdomen shining, the 

 base red, the rest blackish, but more or less tinged with red ; second and following 

 segments distinctly punctured, apical segments with black hairs. All the legs red, 

 the tibiae with a yellow line above : wings fuscous with very little iridescence. 



Hab. Mountains near Honolulu. A single % taken on the blossoms of Acacia 

 koa. Allied to N. setosifrons and perspicua, this remarkable species in general 

 appearance is quite unlike any other.

Hab. Oahu, Molokai, Kona district of Hawaii ; not in the mountains. Rare. 

 Blackburn says ' not uncommon,' and I suspect the species is rarer now than it was 

 twenty years ago. It may be an endemic species, while the two following are 

 certainly introduced, and are now abundant on most of the islands. Had they 

 occurred in the islands formerly, Mr Blackburn would certainly have met with them, 

 as they are common around the houses in Honolulu. I have not identified either 

 from elsewhere, and do not know whence they were imported.
