T. torndtoTj Fabr. This species is subject to vary. 

 I obtained an individual near the Rocky Mountains, so 

 covered with short whitish hair as almost to conceal its 

 color ; it was destitute of the large black spot of the 

 elytra. Two specimens occurred in Mexico, both of which 

 were destitute of the same spot. It is the T. ietropthdl- 

 musy Forster. 



Of this genus are two species ; the tornatory F., and 

 the canteridtor^ Drapiez, both of North America, The 

 latter has received three or four other names from as 

 many different authors, but as they are unaccompanied 

 with descriptions, the above will, of course, take pre- 

 cedence •
