New West Indian Megachile 
51 
submarginal cell nearer apex than the first does to base; legs 
piceous, all the tarsi ferruginous, pubescence whitish, yellow on 
all the tarsi beneath and on the middle metatarsi without; 
spurs pale yellow; claws testaceous basally, ferruginous apically, 
with sharp basal teeth. 
Abdomen ovoid, finely and closely punctured, black pubes- 
cent, the pubescence on the first segment entirely pale ochraceous, 
and segments 1-5 with entire and conspicuous apical fasciae of 
pale ochraceous pubescence; segment 6 rather distinctly concave 
at sides viewed from above, straight in profile, with greyish ap- 
pressed pubescence, that on the basal middle dark brown, with 
rather short black erect hairs at sides basally; scopa white, 
black on segment 6, with a considerable amount of black at 
sides of segment 5, and with a small amount at sides of segments 
4 and 3; apical ventral segment with a free polished apical lip 
which projects slightly beyond the scopa. Length 1 1 mm. 
Type: Male (Type No. 15715, Mus. Comp. Zook); Man- 
grove Cay, Andros, Bahamas, Aug. 1, 1904. Allotype; topo- 
typical (Allen, Barbour and Bryant, collectors). 
This is probably only a subspecies of M. poeyi Guer. from 
which it differs as follows: The male is smaller (11 mm. in poeyi) 
and the legs above the tarsi are piceous (bright red in poeyi ) ; the 
pubescence on the disc of segment 2 is entirely black, whereas in 
poeyi it is entirely ochraceous, and the pale pubescence is nearly 
white, while in poeyi it is strongly ochraceous; in the female the 
apical margin of the clypeus is less strongly denticulate and the 
vertex is somewhat less closely punctured than in poeyi , and the 
bright red legs of the latter at once distinguish it from this form; 
and there is considerably more black pubescence in the scopa of 
the subapical segment in poeyi , being black almost entirely across 
the segment apically. 
Megachile salti n. sp. 
$ . Head broad, eyes converging slightly below, vertex 
broad and flat; ^upraclypeal plate shining and bare, finely tes- 
sellate, impunctate medially, closely punctate laterally; clypeus 
with a rather broad impunctate median area, but rather closely
