The example figured in Vol. I. is not fully mature, but two adults which I refer to 
this species occur in the collection, and of these figures are now added. The abdomen 
is pubescent, and also set with short, black, stout, curved spines. ‘The central posterior. 
eyes are not larger than the anterior centrals.
