‚Last October, while walking between Dartmouth and Stoke- 
Fleming, I picked up a small ant, which was moving in a very 
uncertain and erratic manner, Subsequent examination showed 
it to be a monstrosity of the above named species; the right 
half of the body exhibiting characters strongly characteristic of 
the 4, while the left half resembles the ©. 
The following is a description of the two halves, drawn up 
in parallel columns for comparison. 
LEFT HALF. 
Head red, with darker cloud rea- 
ching from vertex to eye. 
Mandible very large, with 7 teeth. 
Antenna 12-jointed, testaceous, 
with pale hairs ; Ist joint of flagel- 
lum longer than next two together; 
these and the following joints much 
wider than long; apical joint very 
large and stout, as long as two‘pre- 
ceding; scape very long and bent, as 
long as many joints of flagellum. 
Eye small. 
Naturw.-med. Verein 1898, 
RIGHT HALF. 
Head dark brown. 
Mandible schmall (the ant being 
carded I cannot clearly make out the 
form of the right mandible). 
dark, thin, 
with pale hairs; 1st joint of flagel- 
lum stouter than next, but subequal 
to it; the following joints all much 
Antenna 15-jointed, 
longer than wide; apical joint as 
long as on left side, but not nearly 
so stout; scape short and straight, 
only about as long as two joints of 
flagellum, and per se barely half the 
length of that of left side. 
Eye larger; more than tice the 
size of the other, and much nearer 
to the base of antenna.
