of the head, thorax, and gaster are deeper and more blackish and 

 extend further back on the head, leaving only the posterior border and 

 posterior corners yellow. The whole upper surface of the thorax is 

 blackish, variegated with brown, and the transverse stripes on the 

 gaster are more sharply outlined both in the major and minor workers. 

 The yellow portions of the body are more whitish than in the typical 

 ramulorum. 



I have seen numerous specimens of this new variety, which is 

 dedicated to Prof. Aristides Mestre of the University of Havana, 

 from two colonies, one taken by Prof. C. H. Eigenmann at Havana 

 (type locality) in the dead pod of a leguminous vine and one by my- 

 self in the hollow twig of a shrub at Aguada de Pasajeros.

Gundlach took the types of this species at Sarabanda in the Cienaga 

 de Zapata. His collection contains two major workers, a male, and a 

 female cotype (no. 210). I have taken the species in the same 

 locality and also at Cogimar, Bolondron, Aguada de Pasajeros, and at 

 all the points visited in the Cienaga. It nests in hollow branches 

 and the workers are often found running singly on the trunks, branches 

 and leaves of trees. 



74. Camponotus sphaericus Roger. 

 Berl. ent. zeitschr., 1863, 7, p. 146 § . 



Gundlach took this species in the vicinity of Santiago de Cuba. 

 His collection contains a single specimen (no. 316). A single worker 

 minor taken by Mr. E. A. Schwarz at Cayamas agrees well with 

 Roger's description, except that the body is opaque and not shining. 

 The pronotum in nearly twice as broad as long, the white hairs on the 

 body are pointed and the appressed ones are not flattened and squami- 

 form and not abundant on the gaster. The mandibles, legs, and 

 antennae are uniformly red. The specimen measures only 4.5 mm. 

 and is therefore considerably smaller than the types which measured 

 6-6.5 mm. It may, perhaps, represent a distinct subspecies.
