Article XV.— A COLLECTION OF ANTS FROM BRITISH 

 HONDURAS. 



By William Morton Wheeler. 



Plates XI and XII. 



The collection of ants enumerated in the following pages was made 

 during the autumn and winter of 1905-'06 by Mr. J. D. Johnson at Manatee, 

 British Honduras. Although the specimens all belong to known species, 

 they are interesting on account of the locality in which they were taken, 

 as British Honduras is very rarely mentioned among the localities in 

 Forel's admirable monograph of the Central x\merican and ISIexican ants 

 in the 'Biologia Centrali-Americana.' 



PONERIN.E. 



1. Pachycondyla harpax Fabr. — Three workers indistinguishable from 

 the typical form from Texas and Mexico. 



2. Pachycondyla (Pseudoponera) stigma Fabi-. — Numerous workers 

 and a few males from several colonies. 



3. Anochetus (Stenomyrmex) emarginatus testaceus Forel. — Numer- 

 ous workers closely resembling in color the typical form of this subspecies 

 from the West Indies and in having the anterior surface of the petiole 

 smooth above and only moderately rugose near the base. 



DORYLIN^. 



4. Eciton hamatum Fabr. — JNIany soldiers and workers. 



5. Eciton vagans Oliv. — Numerous workers. 



6. Eciton rogeri Dalla Torre. — Numerous workers. 



7. Eciton praedator F. Smith. — Numerous workers. 



8. Cheliomynnex nortoni Maijr. (PI. XI, Figs. 4-9.) — Many workers 

 measuring from 2.5 to mm. in length, from two colonies. There can be 

 no doubt that this ant forages in files like the species of Eciton. It is proba- 

 bly hypogseic like E. ccecum Latr. As Emery has shown, C. nortoni has 

 dimorphic workers. The largest individuals (soldiers) have curved, falcate 

 mandibles with a narrow, hooked apical and two large basal teeth (PI. XI, 

 Fig. 5) whereas the intermediates and small workers have short and pro- 

 portionally broad mandibles, with only two large teetii separated by a series
