declivity oblique like the anterior. The postpetiole is rather longer 

 than broad. The head is still narrower and more elongate than in 

 the type: the antennae are still shorter and thicker. The median 

 funicular joints are extremely transverse, much broader than long, 

 in part almost 1| times broader. Finally, the frontal furrow is 

 distinctly marked. The color is blackish brown, pruinose with 

 pubescence." The types are from Bahia Honda (M. J. Schmitt). 

 This is certainly the most abundant of the Cuban Pseudomyrmas. 

 I have seen it running on tree trunks and nesting in their twigs at 

 Cogimar, near Havana, at Bolondron, Aguada de Pasajeros, in many 

 localities in the Cienaga de Zapata (Rio Hanabana, San Francisco de 

 Morales, Sarabanda, etc) and have received specimens from Cayamas 

 (C. F. Baker and E. A. Schwarz). That it was known to Gundlach 

 as a distinct form is shown by a worker specimen (no. 208) marked 

 " Pseudomyrma sp." in his collection. This specimen was taken at 

 Rangel. Forel records this same variety from Haiti (Mitth. naturk. 

 mus. Hamb., 1907, 24, p. 7.) 



16. Monomorium pharaonis (Linne). 



Formica pharaonis Linne, Syst. nat., 1758, ed. 10, 1, p. 580. 



This cosmopolitan tramp species could hardly be lacking in Cuba. 

 The Gundlach coll. contains a female and two worker specimens 

 labelled no. 23, "Monomorium sp.", but without locality. I have 

 taken specimens in the Hotel Sevilla in Havana and in a hotel in 

 Aguada de Pasajeros. 



17. Monomorium floricola (Jerdon). 



Atta floricola Jerdon, Madras journ. litt. sci., 1851, 17, p. 107. 



Gundlach cites this species under the name M. poecilum Roger 

 from Colon and Bermeja Nueva. His collection contains a female and 

 worker specimen (no. 149), which undoubtedly belong to the well- 

 known tropicopolitan species of Jerdon. It is indeed very common in 

 west central Cuba. I have taken it at Bolondron, Aguada de Pasa- 

 jeros, and in various localities in the Cienaga de Zapata (Sarabanda, 

 Rio de Hanabana, San Francisco de Morales) . It nests by preference 

 in Tillandsias and in hollow twigs, each nest containing numerous 

 queens, sometimes as many as thirty or forty. These queens, as I 

 have shown in a former paper (Bull. Amer. mus. nat. hist., 195, 21, 

 p. 88) are always apterous. The small black males, however, which 

 are much more rarely found in the nests, have well-developed wings.
