HORN EXPEDITION—HONEY ANTS. 
389 
Besides the colour and shape this species dhl’ers from C. injiatus in several 
important particulars, the surface very closely covered with line stri;e, the body 
and head nothing like so Iiairy, the mandibles with two less teeth, and the genitalia 
of the males are very diirerent in structure. The honey contained in the abdomen 
is of a slightly sour taste, not unlike that in the nests of our little native bees 
( Trigona carhonarius). I have much pleasure in naming this tine species after 
Mr. Cowle, who obtained this complete series of this new honey ant at no little 
trouble and inconvenience, digging them out under a semi-tropical sun. In 
another tube are several very slender golden yellow-coloured neuters, together 
with a lot of pupie, which may belong to another species, but I think they are 
probably a minor form of neuter of this species.
