[September 
Melipona orbignyi phenax Cockerell. 
Found by A. H. Jennings at Las Cascadas, C. Z. Dr. 
Wheeler obtained three males and four workers at Triplaris , 
Balboa, March 26-27. He also took seven workers at Ancon; 
five are labelled “on Cordia.” The worker has a dark clypeus 
as in typical orbignyi. Typical M. orbignyi Guerin comes from 
the southern parts of tropical South America. 
Trigona pectoralis Dalla Torre, race panamensis Cockerell. 
Four workers at Triplaris ; Balboa, March 26-27. The spe- 
cimens belong to the race or subspecies panamensis, having the 
hind tibiae fringed with dark hair. The U. S. National Museum 
has typical T. pectoralis from Mexico, D. F. 
Megachile poculifera Cockerell. 
Two males at Triplaris, Balboa, March 27. A characteristic 
feature of this species is the tooth on under side of middle femur 
in the male. In the Brazilian M . curvipes F. Smith, it is the hind 
femur that carries the tooth. 
M. poculifera is evidently widely distributed; four males are 
before me, collected at Guaymas, Mexico in April (E. P. Van 
Duzee). The original type was labelled Mexico (Baker 1785). 
Baker’s note-book appears to have been lost, but it is fortunately 
known (see original description of Prosopis crenulata Ckll., 1905) 
that 1785 signifies that it was collected by H. H. Hyde at Me- 
dellin, State of Vera Cruz, Mexico. 
The Triplaris referred to above is T. americana, and the 
Cordia is C. alliodora.
