to Prenolepis and Paratrechina, as redefined by Emery, 
but is peculiar in the vary small size of the eyes, the short 
palpi, the unmodified base of the gaster, the shape of the 
petiole, the extremely long appendages and the absence 
of spurs on the middle and hind tibise. The pale color, 
small eyes, very long appendages and long pilosity of this 
ant indicate that it must be hypogaeic in habit. This might 
explain why it has not been taken heretofore and why the 
JEnicti, which forage more or less subterraneously, were 
able to reveal its existence. 
The following is another undescribed genus belonging 
to the same tribe (Lasiini) of the subfamily Formicinse. 
Aphantolepis gen. nov. 
Worker: Resembling Prenolepis in the structure of the 
head, thorax and gaster, but with somewhat harder integu- 
ment. Eyes of moderate size; ocelli absent. Mandibles 
small, triangular, decussating, with finely dentate apical 
borders. Clypeus short, not extending back between the 
frontal carinse, which are distinct, subparallel and as far 
apart as their distance from the lateral borders of the head. 
Frontal area and groove obsolete. Antennas rather stout, 
12-jointed, the funiculi but slightly enlarged towards their 
tips. Antennal and clypeal foveas confluent. Palpi long, 
maxillary pair 6-jointed, with thickened basal and elongate 
terminal joint; labial pair 4- jointed. Thorax with deep 
mesoepinotal constriction, dorsally approximated and pro- 
truding spiracles and prominent, highly placed epinotal 
spiracles. Petiole flattened above, without a node. Gaster 
rather large, its first segment truncated anteriorly and in 
life evidently overlying the petiole. Middle and hind tibise 
with well-developed spurs; tarsal claws simple.
