1907.] Wheeler, Ants from British Honduras. 277 



40. Camponotus lindigi Mayr. — A few soldiers and several workers. 



41. Camponotus rectangularis Emery. — Numerous soldiers and work- 

 ers of the light-colored, typical form of this species. 



42. Camponotus claviscapus Forel. — Two soldiers and fourteen 

 workers agreeing perfectly with Forel' s description. There are also in my 

 collection two females and two males taken in Nicaragua by Mr. Wm. 

 Fluck. None of these specimens has any trace of a carina on the clypeus 

 so that I am unable to refer them to Forel's var. carinaia of Guatemala. 

 The female resembles the soldier very closely in the structure of the head 

 and the distally incrassated antennal scapes. The thorax and gaster are 

 long and narrow, the mesonotum being somewhat longer than broad and 

 as broad as the head. The petiole is low and very thick, with blunt hori- 

 zontal superior border when seen from behind. The gaster is nearl}^ 

 four times as long as broad, brown, with the anterior half of the first 

 segment and a pair of large rectangular blotches on each of the succeed- 

 ing segments, yellow. The wings are yellowish hyaline, with yellow veins 

 and stigma. 



43. Camponotus sericeiventris Guerin. — Two solcUers and a worker 

 agreeing in all respects with specimens from various parts of Mexico.
