1925 ] Myrmecophilous Phori dee from the Neotropical Region 311 
membrane yellowish white; antennae, palpi and legs pale brown- 
ish yellow. Four strong postantennal bristles, the upper pair 
nearly twice as far apart as the lower; other frontal bristles very 
weak except the two in the upper row between the ocelli which 
are long and stout; the lateral bristle of this row and the one 
within the eye-margin very small and scarcely differentiated 
from the frontal hairs which are unusually large. Three stout 
bristles below each eye above the oral margin. Proboscis stout, 
oval, nearly as long as the head height. Third joint of antennae 
rounded, the arista rather strongly pubescent, one-fourth longer

than the head height. Eye as large as the antenna; composed of 
about twenty-five facets. Thorax slightly wider than long, with 
a transverse series of six bristles behind, the median pair close to 
the hind margin and farther apart than their distance from the 
adjacent ones which are placed farther forward; lateral bristle 
placed at the posterior third of the mesonotum. Abdomen with 
six dorsal plates; first unusually long, the lengths of the plates 
25:45:29:25:16:8. There is no distinct slit in the fifth segment 
for the opening of the gland but a transverse crescentic or almost 
semicircular clear area indicates its position. That this area 
represents the fifth segment is evident from the furcula (apodeme) 
of the sixth segment which extends forwards at this point (see 
fig. 3) although there is no segmentation of the sides of the ab- 
domen to mark off the fifth segment. Sixth and also a small
