CL 



The expression " petiole of the first siil)niar£rinal cell " 

 is, I realize, incomprehensible to anyone not familiar with 

 the vocabulary of scientific entomology. Therefore on 

 the accompanying cuts are indicated this first submarginal 

 cell and its petiole. The petiole is the vein which runs 



from the end of the cell back 

 to the first cross-vein, and 

 the relative length of this 

 petiole and of the cell it- 

 self are of importance in 

 the classification. 



The names used in this 

 series of tables, and in this 

 book, as a whole, differ in 

 some slight degree from 

 those which have been used 

 in the previous writings of 

 the author, and of Mr. Co- 

 quillett. Oulex tceniatus, for 

 example, a name which w^as 

 used in Bulletin 25, has been 

 decided to be a synonym of 

 Stegoniyia faseiata. In this 

 conclusion Mr. Coquillett is 

 joined by Mr. Theobald, the 

 English author. Oulex excitans of Bulletin 25, is stated by 

 Mr. Theobald to be also a synonym of S. faseiata, from a 

 study of the type specimen. Anopheles argyritarsis has 

 been added, since, although it is not known to occur in 

 the United States, it has been found in Qnha by the Army
