This beautifuDy painted species is remarkable for the 

 brightness and delicacy of its colour, the entire surface 

 being a deej) transparent blood-rose, flaked here and there 

 with white. The specimen here figured is from the choice 

 collection of Mrs. Do Burgh. Mr. Cuming also possesses 

 a fine and equally brilliantly painted specimen.
