1914] Wheeler—Notes on the Habits of American Liomyrex 75 
Apterous male: Pronotum a little broader than long, rounded behind. Last 
dorsal segment of abdomen truncate at apex, last ventral segment arcuately emar- 
ginate at apex. First genital segment ferruginous beneath at the base. Posterior, 
femora very strongly incrassate, not reaching the tip of the apical genital segment 
spined beneath from the apex to a little beyond the middle, the first spine (near the 
middle) the longest, the following gradually diminishing in length toward the apex. 
Posterior tibiz straight, finely denticulate beneath down their whole length, with- 
out large teeth, the teeth of the middle third slightly longer, the apical third slightly 
narrower than the rest. Length, 4 mm. 
Locality: Nicaragua (Granada). 
Allied to Rh. femoralis Champ., but the antenne are differently 
constructed; the venter is not ridged in the middle; the posterior 
tibiz have no large teeth, ete. 
NOTE ON THE HABITS OF LIOMYRMEX. 
By Witit1am Morton WHEELER, 
Bussey Institution, Harvard University. 
The ant genus Liomyrmex comprises four described species, 
cecus F. Smith, gestrou Emery, aurianus Emery and carinatus 
Stitz, all from New Guinea, except aurianus, which has been taken 
hitherto only on the island of Tenasserim, off the coast of Burmah. 
L. carinatus and gestroi are known only from female specimens, the 
other two species only from workers. The complete absence of 
eyes in the latter phase and its testaceous coloration show that 
these ants must be decidedly hypogeic, but no account of their 
habits has been published. 
Recently Prof. C. F. Baker has sent me from Mt. Makiling, on 
the island of Luzon, Philippines, several worker specimens, which, 
except in their slightly smaller size, agree perfectly with Emery’s 
description of the Burmese L. aurianus (Ann. Mus. Civ. Genova, 
XXVITI, 1889, p. 504). Prof. Baker states in his letter that these 
ants were found in the forest, ““abundant with termites—living in 
the same chambers with these in entire amity.’’ The termites, of 
which a number were included in the same vial with the Liomyrmez, 
are workers and soldiers of Termes (Macrotermes) gilvus Hagen, 
which is widely distributed in the East Indies (Singapore, Java, 
Sumatra, Borneo, Philippines, etc.). This must be a formidable 
species, for the larger soldiers measure nearly 10 mm. and are 
furnished with acute and powerful jaws.
