 pterostigma, and are inserted in a distinctly male area. 

 The specimen was not dissected. 



Santschi found this ant in a nest with females at Kai- 

 rouan, Tunis, but without males, either of the winged or 

 of the ergatomorphic type, which is peculiar to this and 

 some of the other species of Cardiocondyla. His atten- 

 tion was attracted by the bizarre movements of the speci- 

 men, as it turned around rather quickly in circles about 

 10 cm. in diameter, with the male portion inside. In 

 other words, owing either to the asymmetry of its brain 

 and visual organs or to differences in the length of the 

 legs on the two sides of the body, it made circus move- 

 ments like a normal insect which has had one of its eyes 

 or optic ganglia injured.

 color of the male being sharply marked off from the dark

 two neither sharp nor straight and the whole postscutel-

 surface. Third dorsal tergite blackish brown on the right, 

 grayish yellow on the left side. Eemainder of gaster 

 grayish yellow, tinged here and there with pale brown. 

 Third tergite with a median longitudinal groove which
