Cockerell describes the head of a female with long massive 

 jaws and part of the body. I have seen three dealated 

 females : one specimen [1. 8702] exhibits the head with 

 massive jaws, outline of thorax, petiole and gaster, and part 

 of tiie femora of all six legs. A number of eggs are visible 

 w^ithin the gaster. Its measurements are as follows : — Length 

 12'5 mm. ; petiole 1*2 mm. ; gaster, long 3'5 mm., broad 



3 nira.; head, long 3 mm., broad 2'5 mm. The second 

 specimen [I. 8711] possesses the left intermediate leg com- 

 plete. It measures : — Length 12"7 mm.; head, long 3 mm., 

 broad 2*6 mm. ; petiole 1'5 mm. ; gaster, long 3'5 mm., broad 



4 mm. The third specimen [I. 9335] consists only of a 

 thorax, petiole, and part of the gaster with some of the 

 segments visible, and a bit of one femur. A specimen of 

 part of a winged female [In. 17313] shows the iiead with 

 large jaws and eyes, thorax with scutellum fairly distinct, and 

 traces of three wings, the petiole, and the two anterior legs. 

 The head is 3 mm. long and 2'7 mm. broad.

On one fragment of rock [(68), I. 9613], bearing remains 

 of Oecophylla wings, are several specimens of what appear to 

 be workers. These are indistinct, but siiow the outline of a 

 head, thorax, petiole and gaster, and some legs, which may 

 well belong to Oecophylla. Tiiese ants are small, being only 

 3*5 mm. in length (the smallest worker of 0. smaragdina in 

 my collection measures 4 mm.), and I am quite unable to 

 decide to which of Cockerell's other species they should be 

 referred. I should say they were too small for 0. megarche. 



I have been quite unable to satisfy myself to which of 

 Cockerell's other species the rest of the two hundred and 

 forty-tive specimens of Oecophylla belong. They are all 

 smaller than specimens of 0. megarche. A chart of the 

 measurements shows that they vary in every possible way — 

 in size, size of wings, and all other measurements. Nor does 

 it appear to me that any good purpose would be served by 

 creating a number of new species, which would probably 

 embrace or ovtrlaj) Cockerell's 0. atavina and 0. perd'ila.
