Pseudomyrma flavidida F. Smith. 



Monomorium minutum cbeninum Forel. 



Solenopsis castor Forel. 



Solenopsis globular ia F. Smith. 



Wasmannia sigmoidea Forel. 



Cryptocerus araneolus F. Smith. 



Strumigenys smithi Forel. 



Dorymyrmex pyramicus Roger (pale var.). 



Prenolepis guaternalensis antillana Forel. 



Brachymyrmex heeri Forel var. obscurior Forel. 



Camponotus abdominalis opaciceps Roger. 



it follows, therefore, that only forty-two forms are now known 

 from Grenada, a small number considering its proximity to Trinidad 

 and the mainland, the fact that Forel has recorded seventy-one forms 

 from St. Vincent, an island of about the same size, and the care with 

 which Mr. Brues collected. 



Formicidae. 



Ponerinae. 



1. Platythyrea punctata F. Smith. — Several workers from Grand 

 Etang and Richmond Hill. 



2. Euponera (Pseudoponera) stigma Fabr. — A single dealated 

 female from Grand Etang. 



3. Leptogenys punctaticeps Emery. — A few workers and males 

 from a single colony from Grand Etang. The male measures 4.5- 

 5 mm. and in color, sculpture, pilosity and the shape of the petiole 

 is very similar to the worker. The head is as broad as long, nearly 

 circular, with very small, lobe-like, yellow mandibles and the clypeus 

 broad, convex but ecarinate, and with a broadly rounded, entire 

 anterior border. The wings are rather short, distinctly infuscated, 

 with brown veins and black stigma. 



4. Anochetus inermis Ern. Andre. — Two workers from Sauteurs. 



5. Anochetus (Stenomyrmex) emarginatus Fabr. — Numerous work- 

 ers and a few males of the typical form from Grand Etang. 



6. Odontomachus haematodes Linne. — Several workers and a 

 winged female from Richmond Hill are of rather large size and blackish 

 coloration and may be assigned to the typical form of this common 

 tropicopolitan ant.
