This tribe is distinguished from the Spathiuue by having the abdo- A 

 men sessile, never petiolate, and from the I{or)ni!ni hy having only ^ 

 two cubital cells in the front wings. It also includes all the wingless ;-; 

 species known in the subfamily. I i 



I am in doul>t as to the sexes of Arhaj^his Ruthe and Pamholus 1 

 Halidav. Mr. Marshall has united l)oth under the genus Pamholus i 

 Halidav, but he has recentlv described and figured what I take to be " 

 a winged form of either Pamholus or Arhaphls under the genus ji 

 Pha^nodus. Pha?nodus is known to me in nature, and has three cubital \k 

 cells, not two as figured by Marshall. Pamholus is known to me in i 

 the female sex alone. j j
