The differences between these two genera are too small to 

 warrant their separation. Thomson's genus is not mentioned 

 in Lacordaire's great work ; but there can be no doubt that 

 this is its right place, and not in the neighbourhood of Ptero- 

 platus, with which it was possibly confounded by Lacordaire. 

 The species of the genera here united, although differing very 

 greatly in size and in the form of the apex of the elytra, both 

 resemble the Lycidaj. I hesitate to admit M. Thomson's name, 

 as it may prove, when its faulty grammatical construction is 

 corrected (as it is sure to be by subsequent authors), to have 

 been already employed in zoology.
