E. (R.) operarium White, B. M. Cat., Long. 309, 1855, is 

 either procerum or simplicicolle ; the locality is given as doubt- 

 fully Indian, and the characters are not sufficient to determine 

 to which of the two species it should be referred. 



4. E. (E.) rufulum Hald , seems sufficiently distinct by the 

 much finer and less mottled pubescence, though very closely 

 allied to atomarium. The correct synonymy of the latter is as 

 follows : Cer. atomarius Drury, = C. pulverulentus De Geer, = 

 Stenocorus marylandicus Fabr., = Callidium maryl. Olivier. 

 The second name was erroneously applied by Haldeman to the 

 species, a variety of which was afterwards described by him as
