A very uniformly marked species easily recognized by the charac- 

 ters given in the key. Feeds normally upon terminal buds and young 

 leaves of apple. There is in the American Museum a specimen 

 labeled " on plum " ; but whether or not this is an authentic rearing 

 record I can not say.

Doctor McDunnough resurrected this name from the synonymy 

 for the species we have been calling versicoloranuni, restricting 

 Clemens' name to a similar form with white costa at base of fore

 but it probably feeds upon many different plants. In the National
