A FINE series of ants recently collected in Jamaica by Professor 

 Brues is of unusual interest because most of them were taken in new 

 localities and comprise several forms new to science or unrecorded 

 in my papers on Jamaican ants published in 1908, 1911, and 1913. 

 There are also a few new records in Forel's paper of 1912 on the neo- 

 tropical ants. I have included these, prefixing all the new records 

 with an asterisk. With the additions and a few changes in nomen- 

 clature necessitated by the study of more abundant material, some 

 70 species, subspecies, and Aarieties of Formicidae are now known from 

 Jamaica. 



1. Platythyrca punctata (F.Smith) \ar. pruiiiosa 'Mnyr. ^ — Mon- 



tego Bay (Amer. Mus. Coll.). 



Forel has shown that the form of this species occurring in Jamaica 

 is the var. pruinosa and not the typical form. 



2. Ectafomma '(Ilolcoponera) .s'triatiiluni Mayr. y. — Newton, 



3,000 ft.; Kingston. 



The series from the former locality comprises 28 workers, from the 

 latter a single specimen which is smaller, more reddish, with less 

 pronounced mesoepinotal angle in profile and longer spines on the 

 hind coxae. It may represent a distinct subspecies, but the material 

 is insufficient to justify the introduction of a new name. 



3. Euponera (Trachi/iiiesopiis) .stigvia (Fabricius). S. — Cinchona, 



5,000 ft.
