Dicyphonia Ball. 



Dicyphonia ramentosa Ball, which I have, taken in western 

 Kansas, seems to me to stand between the flatter, broad-headed 

 Parabolocratus on one side and the sharp-nosed Acurhinus and 

 Cochlorinus on the other. Except in the shorter head and flatter 

 body it represents fairly well the Dorydine group of the old 

 world.

Spanghergiella Sign. 



This genus is tropical or subtropical but vidnerata and 

 mexicana extend into the southern U. S. The single vein of 

 clavus seems the most evident character structurally, but the 

 oblique, red stripes of vertex and pronotum appear constant. 

 Lathrop* has indicated the characters for separating the species 

 and connected the sexes I believe correctly.
