are from Costa Rica. Forel has described a subspecies vincentensis 

 from the island of St. Vincent. It has the legs entirely red and the 

 anterior clypeal projection and posteromedian projection of the petiole 

 are less pointed than in the typical form. 



7. Odontomackus haeinatoda (Linne) subsp. insularis Guerin. y . — 

 Liguanea Plain. 



8. Odontomackus haematoda subsp. insxdaris var. ruginodis Wheeler.

9. Pscudomyrma flavidula F. Smith var. delicatula Forel. S . — 

 Kingston. 



*10. Pseudomyrma eduardi Forel. ^ .— Newton, 3,000 ft. 



A single specimen agreeing perfectly with Forel's description. 



11. Monomorium carbonarium F. Smith subsp. eheninuvi Forel. 

 ^ 9 . — Kingston. 



12. Cardiocondyla cmeryi Forel. cf. — Liguanea Plain. 



A single specimen with the head darker and the epinotal spines 

 somewhat longer than in specimens from other localities in my col- 

 lection. 



13. Solenopsis geminata (Fabr.). y 9 cf. — Newton, 3,000 ft.; 

 Liguanea Plain. 



14. Pheidohfallax Mayr. % 9 .— Newton, 3,000 ft. 

 *15. Phcidole fallax Mayr var. ovalis Forel. 



According to Forel the soldier of this variety, which he recently 

 described from Jamaica, differs from the typical fallax in having the 

 head rather oval, with much more convex sides and much narrower 

 behind. The occipital lobes are narrower, more prominent and more 

 densely rugose. I refer specimens from Kingston (M. Grabham) to 

 this variety, but other specimens from Balaclava (A. E. Wight) seem 

 to be intermediate between it and the typical form. 



16. Pheidolc rodoszkowskii Mayr var. opacissima Forel. 21 g . — 

 Newton, 3,000 ft. 



17. Pheidole megaccphala (Fabr.). %.— Cinchona, 5,000 ft, 



18. Pheidole caribbaca Wheeler. 9 • — Newton, 3,000 ft. 



A single dealated specimen agreeing with the gynetypes taken by 

 Wight at Balaclava, except that the body is somewhat more hairy 

 like that of the following subspecies:
