WHEELER AND MANN: ANTS OF PALESTINE. 171 



The female (dealated) 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 2| times as long as broad ; in profile the dorsal 

 surface of the mesonotum, 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. Monoviorium abeUlei Ern. Andre. ^ . — Wady Feran and 

 Wady Gazelle, Sinai Peninsula; Petra, Palestine. 



24. Monomorium {Holcomyrmex) dentigerum Roger. ^ . — Petra, 

 Palestine. 



25. Monomorium {Holcomyrmex) dentigerum Roger var. haal, var. nov. 



Worker. Differing from the typical form in its decidedly darker 

 color, the body and antennal scapes being castaneous or blackish 

 brown; the discs 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. ^ . — Wady El Katana, Syria; 

 Wady Mojeb, Palestine. 



28. Tetramorium caespitum Linne. ^ . — Petra, Palestine.
