124 Psyche [August 
dle ones with concolorous hair; hind tibize extremely broad, hind 
margin with dark hairs; hind basitarsi broad, the outer apical 
angle produced as a broadly rounded lobe; abdomen pica shining, 
the apical part suffusedly dusky. 
Type: From “Philadelphia Banana R.,”’ Costa Rica (F. Knab). 
U.S. Nat. Museum. Also from Boqueron River, Panama, May, 
1907 (Aug. Busck). The name given is from Musa, the banana. 
Differs from 7. mellea Smith and T. pallida Latr. by the broad 
hind tibia and quite differently shaped basitarsus. From T. 
mellicolor Packard (which M. A. Carriker has taken at Pozo Azul, 
Costa Rica), it differs at once by the shape of the head. 7. melli- 
color is a member of “‘coccofago” group, and has an extremely 
broad head; while the metathorax is black, with a transverse 
testaceous patch. 
Trigona salvatoris sp. nov. (tataira subsp. ?) 
Worker: Length 5-53 mm.; closely allied to TJ. mediorufa 
(Cockerell), with the same black and red pattern of mesothorax, 
but differing thus: head black (faintly reddish), the clypeus dull 
yellow with two dark marks, a pale spot behind lower end of eye 
(in immature specimens the whole head dusky reddish); scape 
dark reddish; posterior half of abdomen suffusedly dusky. 
Type: From S. Salvador, Salvador, August 15 (F. Knab). U.S. 
Nat. Museum. Also from Escuintla, Guatemala (F. Knab). 
Perhaps only a race of 7. mediorufa. 
These bees of the ‘‘coccofago” group, with their very broad 
heads and remarkable habits, may be regarded as a distinct sub- 
genus (Oxytrigona subg. n.), with mediorufa as the type. T. 
mediorufa was described as a subspecies of T. flaveola Friese, but 
the latter name cannot stand, as there is an earlier’ T. flaveola 
Spinola. It is assumed that 7’. coccofago or cagafogo (the name is 
variously spelled) is identical with T. tataira Smith; in fact “‘ta- 
taira”’ is the popular name of the bee. When making comparisons 
in Psycug, 1913, p. 13, I neglected to note that my cotype tataira 
was a male, and that the name was founded by Smith on males 
alone. It seems probable that we shall have to recognize a species 
T. tataira, with various races, as follows: 
Trigona tataira Smith. 
Trigona tataira friesiella n. n. (flaveola Friese).
