32. Crematogaster sanguinea Roger var. torrei, var. nov. 



Worker. Length 4-4.5 mm. 



Differing from the preceding form in color, the gaster being en- 

 tirely black and the head, thorax, pedicel, and appendages deep red, 

 with the posterior part of the head and the middle portions of the 

 femora and tibiae often darker or slightly infuscated. The posterior 

 portion of the head is shining and finely and sparsely punctate. , 



Female (dealated). Length 7.5 mm. 



Resembling the worker in color, but the mesonotum, scutellum, 

 and pleurae are blackish. The thoracic dorsum is smooth and shin- 

 ing, with fine, sparse punctures; the pleurae are longitudinally 

 rugulose. The epinotal spines are short, scarcely longer than broad 

 at their bases and directed backward. The head is distinctly broader 

 than long and its upper posterior surface is very finely, longitudinally 

 striated. 



Described from several workers from a single large colony taken at 

 Aguada de Pasajeros in a dead branch and a single female taken from 

 a hollow twig in the Cienaga de Zapata near the Rio de Hanabana. 

 The variety is dedicated to the Cuban naturalist Dr. Carlos de la 

 Torre y Huerta. 



I find that the form which I described several years ago (Bull. 

 Amer. mus. nat. hist., 1905, 21, p. 94) as C. lucayana from the 

 Bahamas should be regarded as a subspecies of sanguinea. It differs 

 from the typical form of this species in having the thoracic sculpture 

 much feebler and in the more brownish color of the red parts of the 

 body and in having the antennal clubs infuscated. The base of the 

 first gastric segment is more broadly red than in the typical sanguinea. 

 The variety etiolata Wheeler described in the same paper has the 

 sculpture of lucayana but the head, thorax, pedicel, bases of the gastric 

 segments, and the appendages are pale yellow. 



33. Pheidole fallax Mayr.

The type of this species was from Cuba and was sent to Mayr by 

 Gundlach. There are no specimens of it, however, in the Gundlach 

 collection.
