Tetramorium guineense, Fabr


1. Tetramorium guineense, Fabr  HNS  .

(No. 21 a a 21 c). [[ worker ]]. Espece cosmopolite des tropiques.

(21). Not common; found in open places; hill-sides below 1000 ft. The formicarium is made at the roots of grass, generally at the side of and partly under a stone; it is extensive, and may contain several thousand ants. The galleries are half an inch wide, smooth, and extend for five or six inches below the surface, with small chambers, in which the larvae may be found. I have only found one form of worker. The ants are rather active, but not very pugnacious, even when the whole nest is dug up.

(21 a). Fitz-Hugh Valley (leeward), 500 ft.; open dry hill-side. Formicarium at roots of grass, and partly under a stone. The colony contained two or three thousand individuals. Several females were found in the lower chambers. Nov. 4 th.

(21 b). Petit Bordelle Valley (leeward), 1000 ft. The formicarium was a large one, with several thousand individuals. I could find no females, though I dug six inches below the surface. Formicarium like that described above, at roots of grass, and partly under a stone. Nov. 3 rd.

(21 c). Cumberland Valley (leeward). Oct. 10 th. Under a stone, open hill-side. No formicarium observed.
