Trigona pectoralis panamensis subsp. nov. 



Worker with the long pollen-collecting hairs of hind tibia? all black (in typical 

 pectoralis they are entirely pale red). 



Las Sabanas, Panama, Nov. 1911, two workers (No. 15). 



Trigona n. sp.(?). 



Gatun, Panama, Canal Zone, Nov. 11, 1911. A worker in very 

 bad condition; resembles T.fulviventris Gner., but the legs are red, 

 and the hair of head, thorax and legs is entirely fulvous; the 

 mesopleura is also evidently red. So far as can be made out the 

 species is new, but it cannot be described properly without fresh 

 material. 



Trigona ruficrus (Latreille). 



Zacapa, Guatemala, Dec. 13, 1911. 



Trigona ruficrus corvina subsp. nov. 



Worker with hind tibiae and tarsi black. Larger than T. amalthea; wings very 

 dark; mandibles red. 



Zacapa, Guatemala (type locality), Dec. 12, 1911 (Xo. 3); 

 San Jose, Costa Rica, Dec. 27, 1911; Gatun, Panama, Canal 

 Zone, Nov. 11, 1911 (No. 7.); Las Sabanas, Panama. Dr. Friese 

 would not separate this from T.juscipennis, but it has red mandi- 

 bles, and in my opinion belongs with ruficrus rather than with 

 amalthea (fuscipennis) . 



Trigona nigra Cresson = era isonii Dalla Torre. 



This is not in Dr. Wheeler's collection, but I take the opportunity 

 to note that specimens from Belize, sent by Prof. C. P. Baker, are 

 labelled T. hyalinata Lep., det. Friese. 1 It is however plain from 

 Lepeletier's description that they cannot be that species. 



Trigona flaveola mediorufa subsp. nov. 



Worker. Length about oh mm.; orange-ferruginous and black; head extremely 

 large, broader than throax, pale ferruginous, the face suffusedly light yellowish- 

 testaceous; ocellar region black, the black variable in amount, with or without 

 lateral processes; clypeus with a transverse black subapical line; front and face 

 almost hairless, front brilliantly shining, face (with clypeus) finely sculptured with 



1 Professor Baker's species labels were large, and I replaced them by smaller ones. I do 

 not now recall whether "det Fries?" was on the original labels, or was placed there by me 

 on the basis of information sent separately.
