L. subarge7itata Kbv. Under this name I [nopcise U) include 

 several forms which have been separated on color varialon. These 

 are rujiceps 'Ltc. , similis Kbv , and rhoJopus Lee. The differences 

 betwten these forms are given by Dr. Leconte (New Species 1873, 

 p 217) the last named, accidentally omitted, being very like 

 the normal subargentata except that the legs are all rulo testaceous. 

 6. — It is probable that thess are merely sexes of one, stolat.i being tlie 



male, sujfusa the female. 

 7. — This is, without much doubt, that called by the later name d.st- 



iihlus Hald. 

 8. — These two have not been certainl\- identified. 



9. — "The type of /". //'tv/Kj" Xm. , in the British Museum belongs to 

 this {stygicus Sa)') species, but the description does not agree and 

 seems to refer rather to P. suht?iarguia/us." Leconte. In either 

 case the name is a svnonvm and .should be dropped. 

 10. — This is the species known by the more recent name o{ htcida Lac. 

 1 1. — Fhes.: two seem t(> be forms of the variable cupviiea Kby. 

 12. — Alter an examination of a large series o{ Orsodiuhui frc)m all parts of 

 our country I can see no reason why they should not be considered 

 as one species. There is even greater variation in color than the 

 names now known will cover. The published names in the order 

 of date are as follows:

From this it seems that our species has quite as much synonymy 

 as has been admitted for the two principal European species. 



\^.~Hydnoccra rufipes has been placed as a variety o{ humeral is Say, but 

 incorrectly, it is a much paler blue than that, the legs entirely pale 

 rufo-testaceous and the elytra are densely and finely punctured. 



14- — rhis species has since been re-described by Dr. Leconte (New 

 Species, 1873, P- 207) as Pachyla rugipennis, he being apparently 

 unaware of Newman's previous description.
