Four specimens, three from British Honduras (Stan 
Creek, Feb. 19, 1940, Komp coll., and Benque Viejo, Stanton 
Coll.) and one from Panama (Buena Vista, Chiriqui Mt., 
1000 ft. May, ’26, J. D. Smith coll.) have been compared 
with the specimens mentioned by Hine (1. c. 1925) and 
agree with them. T. claurensis Hine must be exceedingly 
close to the present species, the characters used to differen- 
tiate the two by Hine being largely intensity of color, 
claurensis being black, de-filippii dark brown. As I was 
unable to find any specimens of claurensis in the Hine col- 
lection, I am unable to state definitely what the differences 
between the two may be, if indeed they are distinct.
