X'his species I found in the North-Western part 
of the United (States when traversing that country 
with Major Long’s party. It is a remarkable in- 
sect, readily distinguishable by the peculiar punc- 
turing of the elytra, i have two specimens, both 
of wuich are mutillated, so that I am not perfect- 
ly sure it belongs to this genus. 
DAPTUS, Dej, 
D. incrcLssaius, Dej. This insect appears to be 
rare. I obtained an individual in Pennsylvania. 
It has not yet occurred to me in the vv estern 
States. 
CRATACANTHUS, Dej. 
C. pensyhanicus, Dej. is a common insect.—- 
But it is not confined to Pennsylvania as the 
name would seem to imply ; it is abundant^ in 
this state, and I obtained three specimens near 
the Rocky Mountains ; these are somewhat small- 
er than the inhabitants of this vicinity, and of a 
paler colour. 
PANGUS, Zeigl. 
1. P. caliginosuSf Fabr, Dejean refers this 
large species to Pangus, which he makes a divi- 
sion of his genus Selonophorus,
