1916] Girault — New Eticyrtidce from North America 41 



inflates Lubbock, the famous honey ant of Central Australia, 

 recently received from the Museum of South Australia, shows that 

 what I described as Camponotus (Myrmamblys) aurofasciatus 

 (p. 817) is merely the hitherto undescribed minor worker of Lub- 

 bock's species. Forel is probably right in assigning it to the 

 subgenus Mrymophyma.

Signiphora thoreauini sp. nov.

Neosigniphora elongata sp. nov.

 width. Agrees with the description of Signiphora australica 

 Girault (the legs, however, dark except the yellow tarsi and the 

 yellow dusky front legs) ; fore wings clearer near tip and under all 

 of submarginal vein; the marginal cilia at apex are over half the 

 greatest wing width. Hind wings broad. Differs notably from 

 australica in the antennal club which is slender, six or more times
