1924] A Gynandromorph of Tetramorium guineense Fabr. 137 
an 11-jointed left antenna. The right antenna is broken so 
that the number of its joints cannot be ascertained. This and 
similar specimens, which one finds occasionally in Tetramorium 
and other ant-genera, are probably to be regarded as exhibiting 
‘fintersexual” rather than gynandromorphic traits since in the 
case mentioned the number of antennal joints is intermediate 
between the ten of the normal male and the twelve of the normal 
female.
