50. Epitritus emmae Emery. 

 Bull. Soc. ent. Ital., 1890, 22, p. 70, pi. 8, fig. 6 S . 



There is in my collection a winged female of this rare ant taken 

 near Havana by Prof. C. F. Baker. 



DOLICHODERINAE. 



51. Iridomyrmex pruinosus (Roger). 



Tapinoma pruinosuni Roger, Berl. ent. zeitschr., 1863, 7, p. 165 § . 



The types of this species were taken at Cogimar, according to 

 Gundlach. His collection contains two co types (no. 287). I have 

 taken numerous specimens in the type locality and also at various 

 other places (Bolondron, Aguada de Pasajeros, and at various spots 

 in the Cienaga de Zapata (Sarabanda, Rio de Hanabana, and San 

 Francisco de Morales). An examination of these specimens shows 

 that the form differs only in its smaller size and dark color from Iri- 

 domyrmex analis Ern. Andre, which was originally described from 

 Mexico but is common throughout the Southern States. This form 

 is, therefore, to be regarded merely as a variety of pruinosum as 

 Emery formerly surmised. 1 The connection between the two forms 

 is established by a series of worker, female, and male specimens re- 

 cently sent me by J. C. Bradley from Billy's Island in the Okefenokee 

 Swamp of Georgia. The workers of this series are larger than those 

 of the typical Cuban form but of the same form, color, and pilosity, 

 while the females are colored like those of J. analis. I. pruinosus is 

 also common in the Bahamas and in tropical Florida. It nests 

 under stones or in small craters in the soil, and its workers forage in 

 the hot sun in dense files. 



52. Iridomyrmex pruinosus (Roger) var. analis (Ern. Andre). 



Tapinoma anale Ern. Andre, Rev. ent., 1893, p. 148 Q . 



Prof. C. F. Baker sent me three workers from Havana, which agree 

 perfectly in size and coloration with the forms from Mexico, Texas, 

 Arizona, etc. 



1 In his recent account of the Dolichoderinae in the " Genera Insectorum " 1912, 

 p. 26, however, he cites the form as " I. analis var. pruinosa," thus reversing the 

 true relation of the forms.
