I have recently received an example of this southern form from Mr. 

 Howard E warts Weed labeled "Agricultural College, Miss., Oct. 22nd 

 1894." Its conspicuous foliaceous antenna; readily distinguish it and its 

 allies from our other North American Delphacida;. The elytra of this speci- 

 men are whitish hyaline marked with setigerous brown dots. The com- 

 missural nervure is white, broadly interrupted with piceous on the middle, 

 and on the corium is a very oblique piceous band from near the apex of 

 the clavus to the outer angle, exterior to which is a brown cloud intersected 

 by the white nervures. Wings subhyaline, clouded at apex, with strong 

 brown nervures. The disc of the thorax is dull testaceous with the sides 

 brown and the abdomen is deep testaceous or ferruginous broadly marked 

 with black. The long black antenna; are expanded on the superior edge 

 only.
