Described from a single female captured by sweeping grass 
bordering on a cane field, October 29, 1911. Jungle country. 
Habitat: Australia — Babinda, Queensland. 
Type: In the Queensland Museum, Brisbane, the above speci-

This remarkable species, both in appearance (color pattern) and 
in the fact that the antennae bear five ring-joints, is otherwise 
like Tetrastichus Haliday. The ring-joints are extremely short 
like lamellae.
