WHEELER: ANTS OF THE GENUS FORMICA. 545 
125. F. (P.) Korpr Emery. 
F. (P.) korbi Emery, Deutsch. ent. zeitschr., 1909, p. 202, 8 9; Forel, 
Bull. Soc. Vaud. sci. nat., 1911, ser. 5, 47, p. 353. 
WorkKER. Length 2.5-6.5 mm. 
Structure and color of the body almost exactly the same as in 
nasuta. 
Whole body, even in small specimens, opaque, owing to its fine 
sculpture, with a slight bronzy or steel-blue luster, most distinct on 
the gaster. 
Pubescence dense, whitish and appressed. Hairs suberect, long, 
sparse, and obtuse. 
Fremae. Also very similar to F. nasuta. Pubescence as in the 
worker; color black, appendages paler. 
Sultan-Dagh in Anatolia (M. Korb). 
Forel believes that this form may eventually prove to be only a 
subspecies of nasuta. 
126. F. (P.) Moncouica Emery. 
F. nasuta subsp. mongolica Emery, Zichy III Asiat. forschungsreise, 1901, 
p7t5oy S:. 
F. (Proformica) mongolica Emery, Deutsch. ent. zeitschr., 1909, p. 202. 
WorKER. Length 2-4.2 mm. 
Resembling the small worker of nasuta in color and sculpture, 
but the head is proportionally broader, the antennae shorter and 
thicker, the thorax much stouter, and the pronotum narrower in pro- 
portion to the posterior portion of the thorax. Pubescence sparse as 
in nasuta. 
Chara-Gol in Mongolia. 
Emery saw only a few specimens of this species and it is therefore 
doubtful whether larger ones occur. 
127. F. (P.) aperrans Mayr.

Tijdschr. ent., 1880, 22, p. 27; Ern André, Spec. Hymén. Europe, 1882,
