404 THE EMPTY QUAETER

(3) Grematogaster (Sphaerocrema) sp. 7 females from Bir
Fadhil, Madara, Abu Khashba and Hawaya. This species, un-
fortunately indeterminable in the female sex alone, was also ob-
tained by Bertram Thomas in the Rub' al Khali. The venation of
the f orewings is abnormal, the discoidal cell being absent; and it
may eventually prove necessary to create a separate subgenus or
genus for this species.

(4) Crematogaster (Acrocoelia) auberti Emery, subsp. jehovae
ForeL 2 workers from Bani Zainan. This subspecies was pre-
viously recorded from Palestine.

(Ti) Termite.

A single dilated individual of the winged caste from Bani
Zainan—indeterminable without more material.
