Types. — The worker and male are here described for the 

 first time, each from a single specimen. The worker is de- 

 posited in the collection of the United States National Mu- 

 seum and the male in the collection of the Massachusetts 

 Agricultural College. These specimens are not in very good 

 condition. The male is from Colombia and the worker from 

 Pozuzo, Peru. 



Pile rather lons[ and rather fine. Head and malar space very long. 

 Head and thorax black. First and last segtncfits of dorsum of abdomen 

 and legs of females black. Intermediate dorsal abdominal segments of 

 the females ferruginous-red Male abdomen all ferruginous-red above, 

 except first segment. Wings dark. 



Queen. — I have never seen a queen of thi.s species, but I am sure from 

 Smith's and Handiirsch's descriptions that this caste resembles the 

 worker very closely except in size. Smith gives the length of the queen 

 as eleven lines. 



Worker. Head. — Very elongate ; with only dark pile. Malar space 

 much longer than its width at apex, about two-fifths as long as eye. 

 Clypeus rather coarsely, but not very densely, punctate. Third antennal 

 segment nearly as long as fourth and fifth together, the fifth slightly 

 longer than the fourth. 



Thorax. — Entirely dark; the very center of the dorsal disc naked, 

 smooth and shining. 



Abdomen. — Dorsum: segment one clothed with black pile ; segments 

 two to five, inclusive, all covered with ferruginous-red pile ; segment 

 six dark. Venter mostly dark. 



Wings. — Rather strongly infuscate. 



Legs. — Coxae, trochanters, femora and tibiae all dark and with black 

 pile. Metatarsi with fringes short. 



Male. Head. — Shaped and colored much like that of worker, but 

 narrower and tapering more rapidly toward bases of mandibles. 

 Mandibles with a rather heavy ferruginous beard. Malar space very 

 much longer than its width at apex, about two-fifths as long as eye. 

 Clypeus rather coarsely, but not densely, punctate ; sparsely punctate 

 in middle of distal end. 



Thorax. — Dark, as in worker, but the pile finer than in that caste. 



Abdomen. — Dorsum: segment one dark; the remaining segments 

 clothed with rather pale ferruginous pile. Venter mostly dark, but 

 the apical fringes of the segments rather pale.
