L. sabirgentati Kby. Under this name I propose to include 

 several forms which have been separated on color variation. These 

 are ruficeps Lie. , simlis Kby , and rhoiopus Lee. The differences 

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

 p. 217) the last mrm.l, accidentally omitted, being very like 

 the normal subargentita except that the legs are all rufo-testaceous. 



6. — It is probable that these are merely sexes of one, stolata being the 

 male, suffusa the female. 



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

 incius Hald. 



8. — These two have not been certainly identified. 



9. — -" The type of F. picipes Nm , in the British Museum belongs to 

 this (stygicus Say) species, but the description does not agree and 

 seems to refer rather to P. submarginatus." Leconte. In either 

 case the name is a synonym and should be dropped. 

 10. — This is the species known by the more recent name of lucida Lac. 

 1 1. — These two seem to be forms of the variable cupraea Kby. 

 1 2. — After an examination of a large series of Orsodachne from 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. 



13. — Hydnocera rufipes has been placed as a variety oUiumeralis 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- — This species has since been re-described by Dr. Leconte (New 

 Species, 1873, P- 2 °7) as P<-tch\'la rugipennis, he being apparently 

 unaware of Newman's previous description.
