(Paper No. J.) 



BY WM. H. ASHMEAD, JACKSONVILLE, FLA.

 new Aphis affecting Pinus australis belonging to the Section Lachnini. 



Having been studying the Aphididae of Florida for the past two 

 years, a quantity of new material has accumulated on my hands, repre- 

 senting nearl)- all the known North American genera. 



This I now propose bringing to the notice of the Entomological world, 

 at the same time giving a list of all the known North American species in 

 a series of short papers, through the columns of the Can. Ent. 



I desire to express my thanks to my friend, Mr. Allen H. Curtiss, of

 follow Prof Cyrus Thomas.

The species of this genus already described from North America are 

 as follows :
