About 20 specimens, smaller than the above, but apparently all argentata & @ 
and 2 2 were also taken at or near Amara by Captain Buxton in June, July, 
and September. Some of those taken in September were visiting Sunflowers, 
others Zizyphus. 
81. Megachile minutissima, Radosz (?)—13 @f, 14 292, Amara (M); 
28th May to 14th June. 
1 4,2 22, Shahroban (M), 31st 
July. 
I have named these chiefly in consequence of having compared them with 
6 & which I took in Egypt in 1899, and which were determined for me as minu- 
tissima by Professor Friese. But except in size (and not very much even in 
that!) they differ very little from argentata 3 3. Captain Buxton’s 2 2, 
however, certainly differ from argentata 2 2 in having no silvery pilosity on 
the last abdominal segment. All these specimens, both g ¢ and 9 Q, are 
small, but they vary considerably in size, and it is curious that the smallest of 
them all are 29 9! One of these is only 6 mm. long, while another measures 
fully 8 mm. (Radoszkowsky gives 7 mm. as the length of the 9, and 6 as that 
of the ¢). 
82. Megachile rotundata, F.—6 3 3, Astara (P), 2nd July, 1 9, Enzeli (P), 
6th June. 
1 Q, Talish (P), 10th July. 
83. Megachile schnabli, Rad.—3 S$, Amara, 14thand 17th June, 6th 
September. 
[1 2, 6th September, “‘garden below Amara.”’— 
Captain Evans. ] 
All these ¢ ¢ agree with Radoszowsky’s description, except that the colour 
of the abdomen seems to be altogether variable. In one specimen (June 17th) 
it is completely reddish, and the scutellum is red also! In the other two the 
antenne, legs, and venter are red, but the dorsal surface of the body shews 
hardly any tendency to rufescence. The pilosity of all three specimens is very 
dense and silvery, giving them that peculiar sheen which characterizes so many 
desert-frequenting Hymenoptera.
