The antennse are setaceous and pubescent beneath ; the palpi porrected obliquely and bent upwards ; the 

 spiral tongue short ; the wings slightly cylindrical and deflexed in repose ; tlie anterior oblong, with the costa 

 slightly arched, and the apical margin rounded. They are varied with black and white, (whence the generic 

 name), and when the moths are settled on a leaf with their wings lapped round them, they so much resemble the 

 faeces of small birds, (as suggested by Mr. Curtis), that it is often difficult to determine what they are.
