very short, robust feet, proves a close relation to Alomya, to which

PELTASTES Illig.

 bands of the tergum yellow; tibiae black. 



Inhabits Pennsylvania and Indiana.

thorax with a j^ellow line before the wings : scutel quadrate : 

 lateral edge elevated; posterior margin, including the prominent 

 spines, yellow : wings with a tint of ferruginous ; nervures fus-
