EUMENES. CO 



inferior part almost retracted before; its posterior face is eon- 

 vex, not at all or hardly divided by a channel into two ridges: 

 its lateral faces are oblique, and form at their meeting with the 

 hinder part two trenchant vertical edges. Behind the wing scale 

 there is a little process The petiole, at first slender, expands 

 at the extremity more like a small funnel than in a pyriform 

 shape. 



Tin; clypeus of the males is generally not colored yellow as in 

 the division Alpha, but resembles that of the female. 



The most perfect type of this little group is the E. globicollis 

 Spin. 



The characters which call for enumeration are on each side more 

 and more effaced among the species which by their form approach 

 to the type of Division Pachymenes and of the Division Alpha. 

 (For example the E. callimorpha holds almost middle ground 

 between the Division Omicron and Alpha; E Sumichrqsti has 

 a sort of impression at the end of petiole, as in Division Alpha; 

 E. inf emails has the second segment swelled, subcom'pressed, 

 etc.) 



One must not be too particular about the indefinable limits of 

 the divisions. 



A. Thorax quite short, cubic-globular, larger than the pear of 

 the abdomen; the 2d segment of this under titan long (as in 

 genus Tatua), wide-globular.
