WHEELER AND MANN: ANTS OF PALESTINE. 171 
The female (dedlated) measures 3.8-4 mm. and resembles the 
worker in color and sculpture, except that the base of the gaster above 
is yellowish red like the head, thorax, and pedicel and more opaque. 
Head longer than broad, with straight, subparallel sides, distinctly 
excised posterior border and rather angular posterior corners. Thorax 
elongate elliptical, fully 25 times as long as broad; in profile the dorsal 
surface of the niesonotum, praescutellum and scutellum form a 
straight line; epinotum with a pronounced median longitudinal 
impression. Postpetiole not broader than the petiole, distinctly 
broader than long. 
23. Monomorium abeille: Ern. André. 8.—Wady Feran and 
Wady Gazelle, Sinai Peninsula; Petra, Palestine. 
24. Monomorium (Holcomyrmex) dentigerum Roger. 8 .— Petra, 
Palestine. 
25. Monomorium (Holcomyrmex) dentigerum Roger var. baal, var. nov. 
Worker. Differing from the typical form in its decidedly darker 
‘color, the body and antennal scapes being castaneous or blackish 
brown; the dises of the mandibles, the clypeus, front, cheeks, mesono- 
tum, pleurae, and lower portions of the petiole and postpetiole deep 
red; the legs and tips of antennal scapes yellowish brown. 
Numerous specimens from Shiba, Syria and Wady Kerak, Palestine. 
26. Leptothorax tuberum Fabr. var. luteus Forel. 
Three workers from Ain Gleidat, Palestine agree closely with the 
description of this form except that they have the posterior half of 
the first gastric segment and the whole of the remaining segments pale 
brown instead of yellow, like the remainder of the body. We deem it 
inadvisable to describe this form as a new variety on the basis of so 
little material. 
27. Tetramorium striativentre Mayr. 8 .— Wady El Katana, Syria; 
Wady Mojeb, Palestine. 
28. Tetramoriwm caespitum Linné. | 8 .— Petra, Palestine. 
29. Tetramorium caespitum Linné var. forte Forel. 8 .— Baruk, 
Syria. 
30. Tetramorium caespitum Linné var. schmitti Forel. 8 — Baruk 
and Ammik, Syria; Wady Mojeb, Palestine; Mt. Simai, Sinai 
Peninsula.
