5. Polistes hebreus (macensis ?), F.—Of this species Captain Buxton took 
several 2 9 at Amara (M) between November 1917 and June 1918, and seven 
% % at Amara and Baghdad (M) during the same period and in July. [Captain 
Evans found & & later also, viz., in August and September 1918.] 
I have compared these specimens with Fabricius’s original Type of macensis 
in the Banks Collection ; and, like it, they are very pale forms with hardly any 
black markings. In most of them the mesonotum appears quite immaculate. 
But I prefer to call them hebrceus which is the older name, because, after careful 
consideration of all Fabricius’s many descriptions of his hebreus and macensis, 
I can find absolutely nothing to shew why he thought them distinct. Some 
authors hold that the two differ in colour, hebraws being a darker insect. It is 
true that some so-called hebreus and macensis specimens differ in this respect. 
But all the many specimens of both that I have seen appear to be mere individual 
aberrations from a single specific Type, and both forms certainly occur together 
in most of their Oriental habitats, together with many others which are inter- 
mediate between them. The original descriptions are to all intents and purposes 
identical ; and though Fabricius names one from Palestine (hebreus), and the 
other from China (macensis,) he cannot have meant to distinguish them as 
differing in ‘habitat.’ For he gives ‘‘ India orientalis ” as the habitat of hebreus, 
and ‘‘ Macao Indiz”’ (sic !) as that of macensis! On the whole I believe that 
the two names should be treated as synonymous, and that of the two hebraeus 
has “ priority ’’ over the other. 
6. Humenes coarctata, L.—l1 2, Qasr-i-Shirin (P), 24th November 1918. 
This is the mediterranea of Kriechbaumer, the common form in most southern 
districts. Both mediterranea and pomiformis, F, are probably only varieties 
(local races) of the Linnéan species. ;

8. Odynerus simplex, F.—1 @, 2 2 9, Talish (P), 10th July. 
9. Odynerus parietum, L.—1 2, Qazvin (P), 20th September. 
10. Odynerus melanocephalus, Gmel.—6 & 8, 1 2, Amara (M), 3rd March 
to 19th June. 
In the 2 and in four of the six ¢ @ the scutellum bears two distinct yellow 
spots, in another @ they are almost invisibly small, and in the June @ the 
scutellum (as in normal melanocephalus) is immaculate. (I do not suppose this 
character to have any systematic significance, but it is as well to mention it.) 
11. Odynerus chloroticus, Spin.—1 g@ and1 2 Amara, (M), September. 
[1 2, Beit-Na’ama near Basrah (M), 12th 
April 1919.—Captain Evans. ] 
12. Odynerus crenatus, Lep.(?)—1 @, Amara (M), 28th May. 
[1 @ “Four miles below Amara, 17th 
September.—Captain Evans. ] 
These are very highly coloured specimens, but I think they do not differ 
specifically from specimens determined as crenatus by Professor Pérez. 
13. Odynerus transitorius, Morawitz.—9 4 @ and 11 @ 9 of this exceedingly 
pretty little species were taken by Captain Buxton at Amara and Shahroban 
(M). [Captain Evans also found it at Beit-Na’ama (M) on April 12th, 1919.] 
Many specimens, apart from their ‘pictura pallida,’ were largely or even entirely 
red. They were flying in April, May and June, and frequented the flowers 
of an Acacia. [Captain Evans’s specimen occurred “ about Tamarisk.”] The
