SPECIFIC CHARACTERS 



For specific characters in a group sense, the length of the stigmal 

 vein, the depth of the cross furrow on the scutellum, and the type of 

 punctation on the dorsum are all valuable. In Group A the punc- 

 tures are very deep and wide in some species, while in others they 

 are very minute. In a few species the thoracic dorsum is entirely 

 reticulate, or reticulato-punctate. The length and type of hair cover- 

 ing are of especial worth in many instances. Two of the very best 

 of structural characters are the comparative length of the joints of 

 the antenna, and the comparative distances between the ocelli, and 

 the ocelli and eye margins. The comparative size of individuals as 

 well as the size and shape of the head, parts of the legs, and the length 

 of the ovipositor are of unquestionable specific worth. It must be
