least width behind postorbital processes, 6.2; upper tooth row (front of canine 
to back of molar, alveoli), 10.4; lower tooth row, 11.6; length of mandible, 
20.6. 
Remarks.— 1 have had no specimens of true A. palmarum from 
Trinidad for comparison, but, when in the U. S. National 
Museum this autumn, I compared my specimen with all the 
material there, including Mexican and Porto Rican forms. All 
the related species appear to have the legs and interfemoral 
membranes naked. ‘The narrow, inconspicuous, frontal stripes 
and the lack of cheek stripes, farther distinguish the new species 
from its probably closest ally, 4. palmarum.
