ANTS FROM MESOPOTAMIA AND NORTH-WEST PERSIA. 165 
Pheidole pallidula, Nyl., subsp. arenarwm, Ruzsky, var. orientalis, 
Em. 2 ¢. N.W. Persia, 1919 (Buxton); Baghdad, 1918 (Kvans). 
Donisthorpe (Ent. Rec., xxx., 10, p. 165, 1918) has recorded this 
form from Mesopotamia as pallidula isp. Hmery, however, (Rev. 
Zool. Afr., iv., 2, p. 229, 1915), states that pallidula i.sp. is not found 
in Asia, where the form that occurs is a variety, which he there calls 
ortentalis. 
Orematogaster scutellaris, Oliv., subsp. schmidti, Mayr. %. Caspian, 
N.W. Persia, 1919 (Buxton). This subspecies is stated by Kmery to 
differ, apart from its colour, from scwtellaris i.sp. by its habit of nesting 
on the ground, and visiting herbaceous plants instead of trees. Taken 
attending Aphis punicae, Pass., on wild pomegranate. 
C. scutellaris, Oliv. ? var. %. N.E. of Baghdad, 1918 (Evans). 
I cannot detect any difference in these specimens from the typical 
scutellaris, though the ants were found under clods of earth (whether 
or not in a nest is not clear), whereas according to Kmery true 
scutellaris nests and lives on trees. 
Cardiocondyla nuda, Mayr., subsp. mauritanica, For. Tigris, 1918. 
On a card with Playiolepis pygmaea and Prenolepis sp. 
Tetramorium caespitum, L. %. Enzeli, Caspian, March and June, 
1919 (Buxton). 
Monomorium gracillimum, Sm. ¥%. Baghdad, 1917 (Buxton) ; 
1918 (Evans). 
_M. salomonis, LL. %. Baghdad, 1918 (Evans). 
M. buxtoni, sp. nov. Fig. I. 
Onn bh. 2-5-2-6 mm. 
Dirty yellowish-brown ; gaster darker. Pilosity as in abeillei, Hrn. André. 
Head longer than wide, sides feebly convex, no broader in front than behind, 
occipital border slightly concave. Mandibles 4-dentate. Clypeus as in abeillet. 
Hyes in middle of sides of head. Scapes just reach occiput. Thorax incision as 
in abeillei, very slight; base of epinotum almost straight, but not quite so straight 
as in abeillei, forming a more rounded angle with the declivity ; upper surface of 
epinotum feebly impressed (strongly so in abeillei). Petiole higher than in abeillei, 
and not so broad proportionately at base. 
Head, thorax and pedicel entirely opaque (head, pronotum and pedicel shining 
in abeillei) ; head entirely matt, the sculpture being densely and deeply reticulate ; 
and scattered punctures very few. Gaster feebly shining, the first segment 
superficially reticulate. 
Though coming near to Mon. abeilleit, rn. And., the new species, 
besides differing as indicated above, is readily distinguished by its 
colour, André’s species being reddish-brown, with gaster nearly black, 
and by its matt opaque appearance. The head again is not quite so 
broad proportionately in buatoni, and is no broader in front, whereas 
in abeillet the head is wider in front, finely superficially reticulate with 
scattered punctures, besides being shining. The comparison was made 
with an example of M. abeillei kindly lent me by Prof. Emery. 
Kumait, Mesopotamia, 1918. (Buxton).
