ACULEATE HYMENOPTERA FROM MESOPOTAMIA. 9 
a row of slightly curving, suberect, white hairs. Of the hind-legs the femora are 
nearly naked ; but the knees, tibize, and bases of the metatarsi have a beautiful 
snow-white scopa externally, while the other hairs of these joints are absolutely 
black. The present 9 (like Klug’s type) is 11 mm. long. 
58. Lasius pilipes, F.—7 @ @, Resht (P), 18-25th February; 1 2, Enzeli 
(P), 24th April. 
The 2 is that common Continental form which has its pilosity coloured like 
that of the @, (not black as in British specimens). 
59. Melecta armata, Pauzer.—l 9, Resht (P), 25th February. 
60. Crocisa ashabadensis, Radosz.—l 2 , Amara (M), 14th June. 
61. Xylocopa olivierit, Lep.—Il1 @,1 2, Baquba (M), 30th July. 
I have noticed, both in Greece and in Syria, that the ¢ ¢ of this species have 
the curious habit of suddenly visiting flowers in great numbers about the time 
of sunset. Earlier in the day that sex is usually nowhere to be found.

This is a common “‘ Oriental’? species, only exceptionally reaching Palearctic 
districts !

65. Ceratina nigrolabiata, Friese—1 @, Amara (M), 9th September; 1 9°, 
Baquba, 27th July. 
The 2 is very small, and may possibly be some species unknown to me. The 
clypeus is almost impunctate on its disc, and the frontal area and mesonotum 
are very sparsely punctured and shining. But in coloration it exactly matches 
a nigrolabiata 9° named for me by the author of the species. 
66. Ceratina laevifrons, Morawitz.—l 2, Shahroban (M), 21st July ; 
1 2 Baquba (M), 27th July. 
67. Ceratina cyanea, Kirby.—1 ¢,2 2 9, Enzeli (P), 6th June. 
One of the 2 2 is not quite anormal specimen, having a very small 
yellow spot in the middle of its clypeus. But I believe this is merely an 
individual aberration. 
68. Chelostoma emarginatum, Ngl.—1 9, Enzeli(P), Ist May. 
I give this name with some little doubt, because I only know the species 
in literature, and the present specimen has no less than 10 ular hooks, which 
does not agree with Schletterer’s statement in Zool. Jahrb., 1889 (p. 619). 
But its other characters suggest emarginatum, and that species has been pree 
viously recorded from N. W. Persia. 
69. Osmia cerulescens, L.—1 9, Qazvin (P), 17th July. 
70. Osmia indigotea, Morawitz(?)—1 @, 1 9, near Basrah (M), 31st March 
1919. 
71. Osmia panzeri, Morawitz.—1 @ near Basrah (M), 12th April 1919. 
These specimens (70 and 71) were all taken by Captain Evans in the same 
locality and I thought at first that they were conspecific. But the very different 
ventral segments of the two ¢ 4 shew that this is not so, and I believe the
