 like hairs : head equal : eyes prominent, reddish-brown : an- 

 tennae and palpi ferruginous : labrum fnlvous : thorax declivous 

 before and behind ; anterior half and lateral margin armed with 

 numerous short spines ; anterior angles projected over the head 

 in the form of parallel horns; posterior angles elongated back- 

 ward in the form of tubercles ; two hardly elevated tubercles on 

 the middle of the base : scutel rounded, cinereous : elytra, each 

 with two elevated lines, of which the inner one is the most prom- 

 inent and acute, with the blackish-brown and cinereous colors 

 somewhat alternate ; tip near the sutural termination mucronate

Found above the mouth of the Ohio. I have a specimen in my 

 cabinet which is rather smaller ; the elevated lines of the elytra 

 hardly prominent. Seems to have some affinity with Ajmfe cor- 

 nutus of Fabr.
