1 6 : 15 : 15 (small irregularities in outlines make exact measure- 
ments difficult). AME separated from one another by nearly two- 
fifths of their diameter and separated from ALE by nearly three-fifths 
of their diameter. PME separated from one another by slightly less 
than their diameter; separated from PLE by nearly one-third of their 
diameter; laterals contiguous to one another. Chelicerae, maxillae, 
lip and sternum essentially as in male. Legs: 4123 in order of length 
as in male; few true spines present but with many stiff bristles. 
Abdomen: in general, typical of females of the genus; epigynum 
quite distinctive, with essential features shown in Figures 9-10. Color 
in alcohol : very similar to that of male but with gray areas somewhat 
reduced; sternum slightly grayish; abdomen as in male except that 
the grayish stripes on each side of the spinnerets are extended for- 
ward a short distance and somewhat widened. 
Diagnosis. This species appears to be most closely related to 
Grammonota texana (Banks) and Grammonota gigas (Banks) but 
I regard it as representing a new group in the genus. Here the 
cephalic lobes are separated from the eyes, advanced forward and 
separated from the ocular region by a deep cleft. The form of the 
cephalic lobes, position of the eyes, features of the male palp and the 
female epigynum definitely establish it as a new species. 
Records. The described female paratype was taken with the male 
holotype. The collection now contains numerous males and females 
from the following localities in the Panama Canal Zone: Barro 
Colorado Island, Gamboa, Frijoles, Madden Dam Area, Naval 
Station near Coccoli, Fort Clayton, Pedro Miguel, Gatun, Summit 
Gardens and Forest Preserve. All of these were taken during my 
visits to this region in 1950, 1954 and 1958. In July and August, 
1965 I collected more than two dozen of this species in the vicinity 
of Turrialba, Costa Rica.

Holotype. The female holotype is from Boquete, Panama, July, 
1939. The name of the species is an arbitrary combination of let- 
ters. 
Description. Total length 1.94 mm. Carapace 0.71 mm long; 
O.55 mm wide opposite interval between second and third coxae 
where it is widest; nearly 0.22 mm tall; posterior declivity very 
gradual to posterior border; apparently with a recurved shallow 
depression representing the median thoracic fovea. Eyes: eight in 
two rows as usual; viewed from above, anterior row definitely re-
