No. 10. — Antillean Isoptera. 

 By Nathan Banks. 



This paper is based on material in the Museum of Comparative 

 Zoology, American Museum of Natural History, and that of the U. S. 

 Bureau of Entomology and the U. S. National Museum. The prin- 

 cipal part of the collection is that collected by Dr. W. M. IVIann in 

 Haiti; a considerable amount was taken by the late Mr. H. G. 

 Hubbard in Jamaica; the other series are much smaller. 



Not many species have been recorded from the West Indies, but 

 in 1910 Dr. Nils Holmgren in a revision of the'American Eutermes 

 described a number, mostly based on the nasuti only; several of his 

 species are certainly only forms of the old Termes morio, a species 

 unrecognized by him; I believe I have correctly placed all of the 

 Holmgren species. 



As a whole the West Indian termite fauna is simply an extension 

 of the South American fauna, and only slightly modified; all the 

 genera occur in South America. The majority of the species are 

 found in the larger islands, Cuba and Hispaniola (Haiti and San 

 Domingo). Thirteen species, eight genera, are known from Cuba; 

 from Hispaniola twelve species, seven genera; six species are known 

 from Porto Rico, and eight species from Jamaica. In all, twenty -six 

 species and eleven genera. One species, Kasniitermes morio, occurs 

 practically all over the West Indies, but not the Bahamas; Neo~ 

 termes castaneiis is also widely spread, but is not known from many 

 of the lesser Antilles. The genus Constrictotermes is practically 

 confined to Haiti. The Antillean termites may be arranged in two 

 families as follows: 



Clypeus not bilobed; no fontanelle; wings not cihate on margin; soldier 

 never with nasute head; tibia with three apical spines; mandibles 

 toothed Kalotermitidae. 



Clypeus \\ath median groove; fontanelle more or less distinct; wings 

 usually ciliate on margin; soldier with but two apical tibial spines, 

 head often nasute, mandibles often unarmed Termitidae.
