the fungus gardens were seen, and the ants were very inactive, prob- 

 ably owing to the drought. Some of the nests, however, contained 

 males and winged females. 



46. Cryptocerus varians F. Smith. 

 Trans. Ent. soc. London, 1876, p. 606, 2 . 



This ant is cited by Gundlach as C. discocephalus F. Smith. He 

 says that "it lives in the mountains in the western part of the island." 

 His collection contains a female and soldier with the no. 188, from 

 Vuelta Abajo, two workers with the no. 131, and a single worker with 

 the no. 189. No localities are cited for these two numbers in the 

 "Catalogo Numerico." 



47. Strumigenys gundlachi Roger. 



Pyramica gundlachi Roger, Berl. ent. zeitschr., 1862, 6, p. 253 y 

 (nee 9 )• 



Gundlach found this species under dead bark at Cogimar or in the 

 vicinity of Cardenas. This ambiguity is due to the fact that two 

 species were described by Roger under this name (vide infra) . The 

 single worker specimen (no. 135) in the Gundlach collection is a 

 co type of the true gundlachi. 



48. Strumigenys rogeri Emery. 



Bull. Soc. ent. Ital., 1890, 22, p. 31, pi. 7, fig. 6 S . 



The types of this species are from St. Thomas, but Emery believes 

 that the specimen described by Roger as the female of his Pyramica 

 gundlachi belongs to this species. It is not represented in the Gund- 

 lach collection. 



49. Strumigenys alberti Forel. 

 Trans. Ent. soc. London, 1893, p. 380 §} 9 . 



A small colony of this ant, originally described from St. Vincent, 

 was found under a stone in a moist spot in the Cienaga de Zapata 

 about fifteen miles from Bolondron. The species is represented by 

 a dark variety, nigrescens Wheeler, in Jamaica.
