71. Dol. Fece (Emery) race ifuscus (Emery). 



Salween Hills (3,000 ft.), Burma Major Bingham. 



72. Dol. gracilijjes{M.-a.jr). 



Bombay E, H. Aitken. 



Calcutta G. A. J. Rothney (20-7-85 ^J). 



A nest was sent me by Mr. Aitken in 1885. They seem to depend 

 for food on the white woolly 'coccus' (?) so common in the Konkan 5 

 where this occurs they draw the leaves together and form a ' nest.' 



PONERID^. 

 Gen. 16. Odontomachus (Lin.). 

 The extraordinary, bent, three-pronged jaws differentiate this ana 

 the following genus so clearly from all other Foneridm that it has 

 been pi'oposed to promote them to a sub-family of their own. In 

 Odontomachus the knot is armed with a spine at its apex. 

 73» Od. rixosus (Smith). 



Tavoy Plateau (4,000 ft.), Burma Major Bingham. 



74. Od. licematodes (Lin.), 



Travancore H. S. Ferguson. 



Ceylon Major Yerbury. 



Madras; Colombo G. A. J. Rothney. 



I asked Mr. Ferguson as to the jumping powers of Odontomachus 

 and he wrote : " I got some of those which you said were supposed 

 " to jump. I don't think they do, but they can shoot themselves 

 " backwards by bending their heads, pressing their mandibles against 

 " any firm support, and then bringing them together with a click. 

 " I tried them several times, and found that if held by a prelimb, 

 " they always release themselves in this way, using the imprisoned 

 " limb as a fulcrum for the mandibles to work against." 



Gen. 17. Anochetus (Mayr). 

 In Anochetus the knot is unarmed. Both these genera are said 

 to be able to jump.
