NEW AND LITTLE-KNOWN BEES. 159 
hind tibie and basitarsi (except apically) clear ferruginous. 
The general colour is dark olive-green. The mesothorax, with 
the punctures of disc distinct and separate under a lens, is very 
different from that of N. flavoviridis phanerura. The scutellum 
also has a pair of black shining impunctate elevations, not 
present in phanerura. It is very likely that when the male is 
known this insect will be subspecifically separable. 
Trigona carbonaria, Smith. 
Kenthurst, N.S.W., October 9th (Froggatt, 153 c). 
Megachile tarsatula, Cockerell. 
Both sexes come from P. Princesa, Palawan (Baker coll., 3842, 
3843). The female is new; it is about 8:5 mm. long, narrow, with 
the form of the American MW. exilis, facial quadrangle longer than 
broad; mandibles quadridentate, broad, coarsely striato-punctate ; 
clypeus densely and coarsely punctured, the lower margin shining, 
gently concave ; tarsi black, obscurely reddish apically, but middle 
and hind femora clear bright ferruginous, with the knees black ; 
-abdomen parallel-sided; ventral scopa thin, clear white, very short 
and black on last segment. This female, on account of the colour 
.of the middle and hind femora, resembles M. vigilans, Sm., and 
M. moera, Cam. 
Megachile abluta valdezi, subsp. n. 
?. Differs from typical abluta (from Formosa) as follows: 
Mandibles longer; clypeus more coarsely punctured, with a more or 
less distinct smooth median line; greater part of supraclypeal area 
‘smooth, polished, and impunctate; sides of vertex with punctures 
of different sizes; middle of mesothorax with punctures distinctly 
separated, the surface between shining; abdomial hair-bands white 
or creamy white. The ventral scopa is white, black on last segment, 
and there is a patch of long black hairs on each side of penultimate 
‘segment. This differs from M. abluta subrixator, Ckll., in the colour 
of the ventral scopa, but is otherwise nearer to it than to true abluta. 
The males, from the same locality, agree with MW. abluta. 
Hab.—Mt. Makiling, Luzon (Baker coll., 5236, 5235). Males 
from Mt. Makiling (Baker coll., 5234, etc.). We must apparently 
conclude that typical M. abluta does not inhabit the Philippine 
Islands, but is represented by valdezi and subrixator. 
A small male of the abluta type comes from P. Princesa, 
Palawan (Baker coll., 3840). 
Megachile philippinensis, Friese, n. sp. 
This species, named by Friese in manuscript, and now published 
with his permission, is the Philippine representative of the Formosan 
M. tranquilla, Ckll., of which it might be considered a subspecies. 
The lower margin of the clypeus is shallowly subemarginate in the
