in the typical globularia and its vars. lucayana Wheeler and borin- 

 quenensis. 



Described from several workers taken from two colonies living 

 under stones, one at Cogimar, the other near San Francisco de Morales 

 in the Cienaga de Zapata. 



This ant was known to Gundlach, as I find among his unidentified 

 specimens a male and two workers with the no. 319, but without a 

 locality. 



41. Solenopsis corticalis Forel var. virgula Forel. 

 Ann. Soc. ent. Belg., 1904, 48, p. 172 9 . 



The Gundlach collection contains a few specimens (no. 83) which 

 I refer to this variety. They bear no locality. The variety was 

 originally described from Cuba by Forel. 



42. Atta insularis Guerin. 

 Iconogr. regn. anim., 1845, 7, p. 422 9 . 



Gundlach gives a good account of the habits of this, the largest 

 and most destructive of the Cuban ants, which he calls A. cephalotes, 

 and states that it occurs in both the eastern and western portions of 

 the island. His collection contains one male, one female, and six 

 worker specimens (no. 151). 



I have seen it in the following localities: — Cogimar, Bolondron, and 

 Aguada de Pasajeros and have in my collection specimens from 

 Guines and Cayamas (E. A. Schwarz), El Guama, Pinar del Rio, and 

 Guana jay (Palmer and Riley), Baracoa (Aug. Busck), and Santiago de 

 las Vegas (M. T. Cook and C. F. Baker), Holguin, and Puerto de 

 Golpe in Pinar del Rio (P. J. Schmitt). It is known also to occur in 

 the Isla de Pinos. 1 



In the vicinity of Aguada de Pasajeros, both in the sugar cane fields 

 and in the potreros, very large nests of this leaf-cutting ant may be 

 seen. These nests are, in fact, conspicuous objects in the landscape, 

 being great mounds twenty to forty feet in diameter and three to six 

 feet high. The planters and gardeners wage an incessant warfare 

 with this insect.
