A LISf OF ANTS FROM MESOPOTAMIA. 165 
borders usually irregular, colour rarely olive as in alveus, often more 
or less reddish. <‘‘ Rectangle allongé”’ in the space 4-5 and a brown 
spot between it and median band. The “‘ rectangle” is the marginal 
spot in this space, and extends squarely towards the middle of the 
wing as in no other of these species. 
Fritillum.—H.W. underside, colour reddish and marbled with 
darker ; rectangle quite short. Upper side, spots large, conspicuously 
white on a black ground, discoidal spot large and square, in carlinae 
it is smaller and has concave margin (‘‘ signe de Delahaye ’’). 
Onopordi.—H.W. underside, largest spot of band, space 4-5 anvil- 
shaped, inner and outer margins concave; spot in space l-c (‘‘ signe 
de Blachier’’), may be sharply pointed (at inner side of middle of 
space) towards hind margin and hollowed basally, or the immer margin 
is further from the base than the outer, giving the basal and outer 
margins an S curve. It tends to have the spots outlined. 
Serratulae.—Discal spot concave outwards, larger than in alveus, 
onopordi, and carlinae, sometimes nearly as large as in fritillum. H.W. 
underside ground colour of uniform tint, no marbling or dark margin 
-to spots. 
Carthami.—H.W. underside, colour much as in serratulae, but with 
much dark shading and with margins to spots, which makes very pro- 
nounced the arrow-head form of the marginal spots, especially near 
4 and 5. 
Dr. Reverdin gives a resumé (p. 171, Bulletin, Geneva ‘Society, 
vol. 11.) of the characters of these species and (p. 172) of the principal 
details in the differential diagnosis.

These are all very characteristic examples except 3, carlinae, in 
which the “long rectangle” (against hindmargin, hindwing) is of only 
about half its usual length in this species, showing how even this 
character can vary. The specimen was verified by examination of the 
appendages.

Nearly all the following Formicidae were taken by Lieutenant W. 
Hdgar Evans, R.A.M.C. (1.), at Amara, on the Tigris, Mesopotamia, 
a few of each species having been sent to me to name by his father,
