25. Second abdominal segment wholly without basal band or patches of 
tomentum; mesothorax dull; punctures of scutellum very irregular; 
area of metathorax dullish, with strong plicae (Mount Banahao and 
Imugan) melanurops sp. nov. 
Second abdominal segment with basal band or lateral patches of to- 
mentum 26. 
26. First recurrent nervure meeting second transverse cubital ; tongue linear. 
Nesoiialictus robbii (Crawford). 
First recurrent nervure joining second submarginal cell; mouth parts 
ordinary for the genus; hair of postscutellum light fulvous. 
banahaonis Cockerell. 
Halictus itaminus sp. nov. 
Female. — Length, about 6 millimeters ; black, with thin white 
hair, conspicuous on sides of thorax and forming a dense to- 
mentum on postscutellum; head normal, face broad but eyes 
strongly converging below, clypeus somewhat produced; man- 
dibles black, reddish at end; underside of head flattened, finely 
and densely striate; antenme dark, the flagellum faintly brown- 
ish beneath ; front dull, extremely densely punctured ; ^clypeus 
irregularly punctured; mesothorax shining but not highly pol- 
ished, the punctures distinct and well separated, the median 
groove well developed ; scutellum convex, shining, sparsely 
punctured, with no median groove ( H . gedensis has it dullish, 
with a median groove) ; area of metathorax appearing roughened 
(but under microscope seen to be reticulated) at middle and 
base, the posterior part at side being smooth (microscopically 
tessellate), while the posterior middle is somewhat swollen, 
with a median depression ; posterior truncation dull except 
upper part, which is shining, its sides angular; sides of thorax 
dull, except a shining area below the wings; tegulge piceous; 
wings dusky, stigma (which is large) and nervures piceous; 
first recurrent nervure meeting second transverse cubital; legs 
black, with pale hair; hind spur with long spines; abdomen 
shining, with white hair bands, broadest laterally (not always 
clearly visible) at bases of second and third segments; venter 
with white hair. 
Male . — Very much like the female, but smaller and slenderer ; 
clypeus entirely black; legs entirely dark; mesothorax shining. 
Luzon, Laguna Province, Mount Maquiling, 10 females and 
8 males (the type is a female); Mount Banahao, 1 female: 
Mountain Province, Baguio, 1 female. All from Baker. 
This is very close to certain species of Java, H. gedehensis 
Friese and especially H. gedensis Ckll, differing from the latter 
especially in the scutellum, as is indicated in the preceding 
description.
