ACULEATE HYMENOPTERA FROM MESOPOTAMIA. 193 
37. Andrena cyanescens, Nyl.—1 92, Amara (M), 24th March. 
I think this determination is correct, but the specimen has met with an accident 
and the femora, tibize and tarsi of both hind-legs are missing ! 
38. [Andrena vetula, Lep.—1 2, Basrah (M), 6th April 1919.—Captain Evans. 
39. Andrena cordialis, Morawitz.— 1 9, Basrah (M), 3lst March 1919.— 
Captain Evans. ] 
T know this species only from the author’s description, but the latter seems to 
agree well with the characters of the specimen before me. 
40. Cilissa leporina. —l 92, Qazvin (P), 17th July. 
41. Noma diversipes, Latr—l 3, Qazvin (P), 27th July. 
42. Nomia edentata, Moraw.—22 ¢ 5-172 9, Amara (M), Ist June to 9th 
September.

The integument in these specimens varies greatly in colour; it may be 
entirely black, or the abdomen and propodeum may be largely, or even entirely 
red. The most highly coloured examples before me are males, but at least one 
2 has the whole abdomen dark red. I believe this is merely a matter of indi- 
vidual aberration. It does not seem to be accompanied by any structural 
differences. 
43. Nomia rufiventris, Spim.—1 2, Amara (M), April. 
Spinola’s description suits this specimen perfectly. I believe that Morawitz’s 
rufescens is the same species. The puncturation is very sparse and feeble, and the 
basal pilosity of the abdominal tergites consists of long, thin, (not at all scale- 
like}, hairs. The abdomen (but not the propodeum) is entirely red, except the 
apical margins of the tergites, which are bright yellow. 
Eucera dentata, Klug.*—1 3, Enzeli (P), 14th June. 
45. Hucera malve, Rossi.—1 3.1 2, Talish (P), 10th July. 
1 3, Enzeli (P), 14th June. 
46. Hucera radoszkovskyt, Morawitz.—1 3,1 9, Qazvin (P), 17th-24th July. 
47. Hucera distinguenda. Morawitz.—l 3, Amara (M). 
[1 3, Beit-Na’ama near Basrah (M), 
12th April 1919.—Captain Evans. ] 
48. Hucera longicornis, L.—l 3, Amara (M), 15th February. 
3 2 2, Amara (M), 24th March. 
1 9, Amara (M), 30th March. 
These appear to me to belong to the true longicornis, L., having the thorax 
punctured just as in specimens from Britain and other North European countries. 
49. Hucera tuberculata, F.—1 3, Resht (P), 20th March. 
1 9, Resht (P), April. 
This species is the longicornis, L., of Friese in Bienen Europa’s, but apparently 
not that of Linné. In calling it twberculata I am following the opinion of Herr 
Alfken, Bienenfauna von Bremen (1913). 
50. Nomada fucata, Panzor.—l ¢, Amara (M), April. 
51. Nomada tigridis, n. sp.—1 3, Amara (M), 30th March. 
4 2 2, Amara (M), 28th May-8th June. 
This is a fairly large and conspicuously coloured species, but I can find no 
description to suit it, though several more or less similar forms are recorded by 
Morawitz (robusta, regalis, etc.) 
The antennz in both sexes are short and thick with the 3rd joint somewhat 
shorter than the 4th and the joints near the apex about as broad as long. The 
mandibles are acuminate ; the labrum has a very slight central tuberculation 
(hardly to be called a tooth) at its apex. The 2 hind tibiz have incrassate apices 
with a sort of small black knob-like projection at each corner (as viewed from 
behind), between which projections three or four pale subequal spines may be 
— 
* This and the next three spp. belong to the Macrocera division of Eucera.
