9. S. CYANiPENNis Fabr. — The allied species of the United 

 States was considered by Gravenhorst as a variety only of the 

 European species. I have not at present in my collection the 

 true cj/anijjenm's of Europe to compare, but as Gravenhorst mentions 

 a difference in the size of the head, it may yet prove to be a dis- 

 tinct species, and, if so, the name proposed by Knoch, S. cyanop' 

 terns, will be an appropriate one. Fam 1st. 



[Also a Philonthus. — Lec] 



10. S. viDUATUS F. — This name has the priority over that of 

 maculosns Grav. Belongs to Family 4. It is singular that Gra- 

 venhorst, in his revised work the " Monographia, " quotes the 

 proper name of this insect and yet retains the synonym of macu- 

 losus as the true name, although it was given by himself a year 

 after the Fabrician name. 



11. S. VIOLACEUS Grav. — This species is subject to vary con- 

 siderably ; the " linea media longitudinali laevi " of the head is 

 very commonly obliterated by punctures, and there exists a variety, 

 of which the elytra are tinged with greenish, or are dusky brassy. 



Belongs to Fam. 3. 



12. S. UMBRATiLis Grav. — My specimens, five in number, 

 have about [452] five punctures in the dorsal series, neither of
