A specimen from British Honduras is before me, and as 
‘‘Honduras’’ was a type locality for both Walker’s names, it 
may be taken to represent the typical form. This speci- 
men, and another from Panama, have the eyes (revived) 
with 2 broad green transverse bands and the lower margin 
green. Four females from Mexico, two of them from Osten 
Sacken’s collection and determined by him as albonotatus 
Bell., and two from Vera Cruz (Crawford), differ from the 
Honduras and Panama specimens in having an additional 
short green stripe on the eyes, above the other two, and in 
the frons being slightly narrower and more convergent. If 
further material should show these slight differences to 
be constant or correlated with geographical distribution, 
albonotatus might be retained in a varietal or subspecific 
sense. Bequaert, (1931, Journ. New York Ent. Soc., 
XXXIX, p. 541), discussing material from Yucatan and 
Honduras, remarks that most of his material has the eye 
two-banded, but that more rarely there is a third band 
above the other two. The records of Bodkin and Cleare 
and Dunn probably refer to other species. 
Distribution: Mexico to Panama; “Colombia” (Walker).
