Xylocopa fallax mcgregori subsp. nov. 
Abdomen in both sexes black, wholly without any green tint, 
and the first two segments without any distinct hair bands; 
antennse black, reddened only at end of last joint; anterior wings 
of male, 22 millimeters long, rarely 23 (26 in typical fallax) ; 
of female, 21 to 24.5. 
Luzon, Manila, July 24 and 25, 1919, type, at flowers of Pel- 
tophorum inerme (Roxb.) Naves, 22 females and 6 males; Ma- 
nila, July 26, 1 male at Antigonon leptoputs Hook, and Am.: 
Bulacan Province, Obando, October, 1919, 1 female. All col- 
lected by R. C. McGregor. Two males, previously recorded as 
X. fallax, obtained by Baker at Baguio, differ from the above by 
the distinctly paler wings ; the anterior wings measure 21.5 mil- 
limeters in one, 24.5 in the other. The Baguio form, when better 
known, may prove to be a separable race. 
Xylocopa fallax was described by Maidl from two females and 
a male collected by “V. Schadberg” [doubtless von Schadenberg] 
in the Philippines, the particular island not stated. With the 
long series of fresh specimens before me, it is evident that the 
Manila form is not typical, though there appears to be no reason 
for regarding it as a distinct species. Presumably typical fallax 
is from some other island, and at present unknown to me. 
The resemblance of X. fallax mcgregori to X. pictipennis 
Smith, from Java, is so close that I was inclined to consider it 
identical, until I noticed that pictipennis has the third antennal 
joint conspicuously longer, and the punctures on the clypeus 
larger and not so dense. I have a pictipennis from F. Smith’s 
collection. Xylocopa pictipennis is larger than mcgregori. 
Xylocopa nigrocserulea Smith. 
Prof. C. F. Baker calls my attention to the fact that Gribodo 
records this from Mindoro, Palawan, and Mindanao. I have 
not seen it from the Philippine Islands; the wings are brown, 
not dark, with coppery iridescence; pubescence black; abdomen 
blue-black. It was described from Celebes, but according to
