BORNEO, Sandakan. Nearest to N. testaceobalteata Cameron 
from Kuching, Borneo, but easily known by the almost entirely 
red color, like that of a female. It is very distinct from all the 
Philippine species. 
Genus MEGACHILE Latreille 
Megachile tarsatula Cockerell. 
A female from Sandakan (Baker 9969) does not differ from 
those collected in the Philippines (Mindanao, Palawan, and 
Negros). 
Genus PROSOPIS Fabricius 
Prosopis opacissima Cockerell. 
Male.—Length, about or nearly 5 millimeters; not very ro- 
bust; black, with the following parts lemon yellow: Clypeus, 
cuneiform lateral face marks (filling space between clypeus and 
eye, and ending broadly but obliquely above at antenne), labrum 
except margin, greater part of mandibles, interrupted band on 
prothorax (not nearly reaching tubercles), tubercles, spot on 
tegulz, anterior tibiz except a large spot behind, basal half of 
middle and hind tibie, and all the tarsi (small joints rufescent). 
Eyes strongly converging below, so that lower part of face is 
narrowed; antennz long, scape with a yellowish stripe, flagel- 
lum dusky ferruginous beneath; front densely and minutely 
punctured; mesothorax dull and densely punctured; scutellum 
with larger less-crowded punctures; area of metathorax with 
transverse sulci, the whole effect resembling the picture of a 
bird in flight; wings dusky, stigma and nervures dark, first 
recurrent nervures meeting first transversocubital; abdomen 
shining on first two segments, with excessively fine punctures,
