Bangalore, 4-11-1911. — "Nest lying by itself in garden of 

 Good Shepherd Convent. Solid superstructure, rather smooth, 

 not showing the slightest external aperture. Mound broad at base, 

 tapering towards top, and ending in a few separate massive 

 pointed peaks ; total height 4'-2". No fungus-beds whatever had 

 been constructed in overground portion of nest ; they began only 

 level with the surrounding ground and continued downwards for 

 a considerable depth. King and queen (the latter rather thick but 

 only 6 cm. long) in cell almost at bottom of superstructure, i.e., 

 nearly level with surrounding ground, in centre of nest. In block 

 of red soil containing royal cell no chambers, neither for eggs nor 

 larvas, only some widened galleries (see photo 1). Strikingly 

 great number of soldiers in royal cell. The bite of the soldiers 

 is not excessive, but their secretion stains very strongly.
