Note. Larger than the following species. Head not so thin, 

 abdomen not so compressed. 



linearis Walker, Entom. Mag., Ill, 1835, p. 189, n. 79. 



Note. It is open to the doubt whether this species is iden- 

 tical with T h о m s о n's obsciirus. Thomson insists Spintherus 

 obscunis hab vingoth mandibles three-dentate. I dissected quite a lot 

 of females and males of this species and never found both man- 

 dibles less than four-toothed. I give here the description of this 

 species. 



Spintherus linearis Walker.

 times as long as first funicle joint; others funicle joints increase in
