and finely punctured ; tegulse piceous. Wings dusky, the 

 costal region strongly brownish ; nervures sepia. Legs 

 with pale hair ; anterior tarsi simple ; anterior coxfe with 

 spines of moderate size, the face of the coxa above the spine 

 sliining, with no special ornamentation ; spurs yellowish 

 white. Abdomen short, first segment with long hair like 

 that of thorax ; second to fifth with entire ochreous hair- 

 bands, rather thin on second, dense on the others ; discs of 

 second to fourtli with very short fuscous hair, only seen in 

 lateral view ; nearly basal two-thirds of fifth segment covered 

 with conspicuous ochreous tomentum ; sixth segment above 

 densely covered with golden-ochreous hair, but the margin 

 of the keel bare ; keel of sixth segment strongly emarginate 

 in middle, but the edges of the emargination not dentiform, 

 the margin on each side of the notch may be indented, but 

 is not at all dentate; no evident ventral spines. There is no 

 hair-band in the scutello-mesothoracic suture. 



Hab. Argentina (O./F. Thomas-, Brit. Museum, 1904. 148). 



In Jorgeusen's Mendoza table and Friese's Argentine table 

 this runs to " simillima"=parsonsia>, which is really a very 

 different species. In VachaFs table of male Megachile it 

 falls nearest to M. pallefacta, but it is not that species, nor 

 is it brasi/iensis, near to which it falls in Friese's table of 

 species of the Brazilian subrcgion. It does not agree with 

 any description I ran find, but it may possibly have been 

 described from the female. 



Megachile abluta, Cockerell. 



c? .—Los Banos, Philippine Is. (Baker, 1792, 1793, 179G) ; 

 Mt. Makiling, Luzon [Baker, 1795). 



I am surprised to find that I cannot separate this species 

 from M. abluta, descri))cd from Formosa. It has very 

 possibly been spread by man, the nests being easily carried 

 in timber or merchandise. The mesothorax of the Philippine 

 Islands specimens is less hairy than that of the Formosan 

 examples before me, but the character varies, and it is 

 impossible to draw any specific lines. The species is easily 

 known from M. taticeps, Sra., by the spined coxaj. 



A male of M. abluta was sent by Professor Baker with a 

 female Megachile, which lias received a manuscript name 

 from Friese. I find, however, another male from Los Banos 

 •which, though allied to ablvta, is distinct, and evidently 

 belongs with Friese's new species.
