Ants from Mesopotamia aud North-West Persia (concluded). 
By W. C. CRAWLEY, B.A., F.E.S. 
Sub-family V. Camponorinm, Forel. 
Acantholepis frauenfeldi, Mayr. 92° %. N.E. of Baghdad, 1918, 
and several other localities (Hvans). 
Plagiolepis pygmaea, Latr. %. Amara, 1918 (Hvans). 
Prenolepis (Nylanderia) jaegerskioldi, Mayr. Baghdad, 1917, Amara, 
1918 (Buxton). N.E. of Baghdad, 1918 (Evans). 
Lasius alienus, Forst. %. N.W. Persia, 1919 (Buxton). 
L. emarginatus, Ol., var. nigro-emarginatus, For. 3 29 3. N.W. 
Persia, 1919 (Buxton). Attending Aphis buxtoni, Theo., on Umbel- 
liferae. 
These examples of this intermediate variety come nearer to 
emarginatus than to niyer. 
L. brunneus, Latr. %. Hnzeli, Caspian, 1919 (Buxton). } 
Though somewhat paler than the typical brunneus, and having the 
frontal eroove less distinct, they appear in all other respects identical 
with the type. — 
Cataglyphis albicans, Rog., subsp. viaticoides, And., var. lutea, Km. 
8. Amara, 1918 (Evans). 
C. albicans, Rog., subsp. viaticoides, And., ? var. N.E. of Baghdad, 
1918 (Evans). ‘These specimens seem to vary slightly from the typical 
viaticoides, but not sufficiently to constitute a true variety. 
C. bicolor, F., var. turcomanica, Km. 9%. Tiflis, 1919 (Buxton). 
Cataylyphis bicolor, F., var. protuberata, var. nov. . 
8 Major. L. 9:0 mm. 
Colour (type), dark brown-black; funiculi and tarsi reddish-brown, gaster 
with a faint metallic lustre. 
The colour in head and thorax varies from dark brown, almost black, to a 
dark red, lightest on head, deepening along the thorax to the petiole which is dark 
brown. In the red forms the articulation of the legs, the antenne and mandibles, 
arered. ‘he apex of each segment of gaster has a pale yellowish border. 
Fourth joint of maxillary palpi slightly longer than 3rd, the 5th much longer 
than the 6th. Palpi fringed with moderately long hairs, not so long as in bicolor. 
Head quadrate; clypeus with central portion raised and with a slight keel. the 
anterior border feebly concave. Hyes situate in posterior 3rd of sides of head. 
The scape passes the occiput by a 3rd of its length. Mesonotum in profile feebly 
convex or quite flat; on each side, just below the centre, the mesonotum bears a 
short blunt protuberance, slightly sloping forwards. These protuberances vary in 
size, are largest in the largest 3 , absent or barely discernible in the % media, and 
entirely absent in the small 3. Node of petiole viewed from above, rounded, 
slightly broader than long ; in profile it is broad and low, rounded above, convex 
anteriorly and nearly straight behind. Legs very long. 
Mandibles coarsely striate. Head entirely matt and microscopically reticulate 
with a few punctures on cheeks. Frontal area somewhat shining. Sculpture on 
thorax and node similar to that on head, but moré shining. Gaster micro- 
' gscopically reticulate. 
A moderately long beard under chin ; a few long hairs on clypeus; a few short 
ones on pronotum, epinotum and scale. A grey pubescence on thorax, epinotum 
and scale, most abundant on epinotum. Antenne without hairs. 
% Minor. UL. 6:0 mm. 
Head red, thorax and node darker red. Anterior border of clypeus more 
distinctly emarginate. Scapes proportionately longer ; mesonotum saddle-shaped 
and without protuberances, the node lower, and the whole insect more slender. 
Otherwise resembles the § major. Length of scapes and shape of mesonotum in 
3 media intermediate between ¥ maxima and minima. Amara, 1918 (Buxton). 
I have given a somewhat detailed description of this variety of
