undescribed short-winged form, tbus far only taken in Missouri, which 

 lives among and feeds upon the oaks only of that region. The present 

 species is also evidently undescribed, unless the mature insect should

The larva 1 and pupae are of rather bright color, giving them a gaudy 

 appearance. The ground color of the body is dark wood brown deep 

 ening into black along the sides of the pronotum and the apex of the 

 posterior femora. The head for the most part is of a bright lemon yel-

 are rather robust in form, with short, broad heads and powerful jaws
