In venation of clavus which VanDuzee makes one of the 

 principal characters for the genus this species agrees perfectly 

 with Dorycephalus and about the only basis for separation is the 

 shorter, more triangular furrowed head and the black color.

Memnonia Ball. 



This genus is placed by VanDuzee next to Xestocephalus 

 in the Acocephalini but in general fascies and shape of 

 head and especially in the position of the ocelli these 

 genera seem to be more closely related to Parabolocratiis 

 or Dicyphonia and in depth of head and rounded margin nearer 

 Nionia and Drionia. I took M. consobrina Ball as far east as 

 Ottawa County, Kansas. (Fig. 2c). I have it also from Clay 

 County of that state.
