from various localities in Cuba: Havana, San Bias, Baragua and 
simply “Cuba” or no locality (some also seen by Giordani Soika). 
However, one is from the Isle of Pines, and so assignable to pineto- 
rum. These specimens show extensive variation in the extent of 
yellow on the mesosoma and the color of the metasoma, so that the 
color distinction does not hold up here either. Since pinetorum is 
thus not “a distinct color form” (Bequaert and Salt, 1931), I syn- 
onymize it with the typical form. 
Summary 
Subspecies concepts in the eumenine genus Zeta are discussed. 
Examination of subspecies in the genus distinguished by color alone 
indicates that the distinctions between them do not hold up, and the 
following are synonymized: orbignii (Saussure), dives (Zavattari), 
riojanum (Bertoni), hubrichi (Giordani Soika), incarum Giordani 
Soika, distinguendum Giordani Soika, apurimacense Giordani 
Soika, pallidior Giordani Soika and peruense Giordani Soika with 
typical argillaceum (L.); pinetorum (Bequaert & Salt) with confusum 
(Bequaert & Salt). 
Acknowledgments 
I thank Peter J. Landolt for sending the Florida specimen which 
occasioned this work. J. K. Liebherr made the specimens of Cornell 
University available for study. Arnold S. Menke arranged the loan 
of material from the U.S. National Museum, and made valuable 
comments on the manuscript. This research has been supported by 
NSF Grant BSR-8508055 to the author.
