The close resemblance that several species of Oedemeridae 

 bear to certain members of this family is very remark- 

 able, and in the company of which they are usually 

 found. The most common and striking instance of this 

 is Fseudolychus haemorrhoidalis, Fab., which is usually 

 found in the company of Mctriorrhyoichiis rufi.pennis, Fab., 

 which it strongly resembles, and like that species it varies 

 from a form having the entire elytra reddish, to one in 

 which only their tips are reddish. P. marginatus, Guer., 

 haemopterus, Guer., and wallacei, n. sp.,* also resemble 

 various species of Lycides.
