LtNCECUM (Proc. Acad. Nat. Sci. Phil. 1866, pp. 101-106) describes the 
habits of the small, black, erratic Ant ” of Texas. The same author (/. c. 
pp. 4-6) describes a battle between two communities of the large Black Tree- 
Ants of the same country 
Myrmica molefaciens. Under this name Lincecum describes a species of 
Ant inhabiting Texas, which he also denominates the Agricultural Ant ” 
(Proc. Acad. Nat. Sci. Phil. 1866, pp. 323-331). The author describes the 
habits of this species in great detail ; it lives in the ground in large commu- 
nities, forming extensive paved ways, and cultivating a particular species of 
grain-bearing grass (Aristida stricta), 
Atta cephalotes. Poey indicates (Report. Cuba, i. pp. 866-868) the general 
natural history of this species in Cuba (whore it is known under the name of 
Bihijagua or Vivijagua) and the damage done by it to agriculture by the 
destruction of cultivated plants. lie describes a method of destroying tlio 
insects by the fumigation of their nests. 
Myrmica lohicornis (Nyl.) occurs as a littoral species in small communities 
under stones in sandbanks in Durham and Northumberland (T. J. Bold, Ent. 
M. Mag. ii. p. 234). 
Cryptocerus clongatus is said by Peckolt to bo destructive to nests of Tri- 
gona mosquito. Smith, Ent. Trans. 3rd ser. v. p. 327. 
Giraud (Ann. Soc. Ent. Fr. 4® s4r. vi. pp. 476-477) notices 3 species of this 
family as inhabiting the dry stems of the Bramble (see p. 417).
