seventh tergite present. Legs rather slender, the four posterior 
tibiae each with a single small apical spur; hind metatarsus with 
six transverse rows of bristles. The abdominal membrane is 
covered with conspicuous dark chitinized specks, each bearing a 
minute bristle; these extend also over the entire venter but are 
absent on the sides except on the last two segments. 
Type and one paratype from Ototonilco, Jalisco, Mexico 
(W. M. Mann), taken in a nest of a species of Pheidole. 
The absence of a distinct fifth tergite and the well developed 
sixth and seventh tergites seem to distinguish this form from any 
others described although to judge from his figure, it is possible 
that P. pusillima de Meijere may have a similar conformation of 
the abdominal plates. De Meijere indicates however only five 
tergites with a space between the fourth and fifth. In my spe- 
cimens of the present form the apodemes described by Schmitz 
as arising from the sixth segment are very clearly to be seen arising 
from the anterior margin of the penultimate tergite. Under a 
very high power (oil -immersion) it is seen that they are attached 
to a small median plate more or less separate from the one I have 
called the sixth, but I think the larger part must be the sixth and 
not a seventh tergite. 
Chonocephalus jamaicensis Brues. 
There is a single female of a species of Chonocephalus from 
Costa Rica bearing the label “with Coptotermes niger Snyder (Coll. 
F. Nevermann). After a very careful examination, I cannot 
distinguish it from C. jamaicensis Brues 1 . In Jamaica, at least, 
this species is not associated with either ants or termites and 
such seems usually to be the case with members of this genus 
although Borgmeier 2 has described C. ecitophilus taken with 
Eciton in Brazil. I am therefore satisfied that the association 
of the present specimens with termites is accidental.
