The description of this species, from its little known medium of 

 publication, has escaped the notice of entomologists and appears 

 in no record or catalogue. It was found by Mr. S. Green on the 

 underside of the Brinjai leaf (Solanum melongena), where it 

 " undergoes all its changes from the larval to the perfect state.'"
