1 Saviguy's plates were issued without explanation in 1813. In 1827 Audonin pub- 

 lished an explanation of them. Von Martens believes this is not the Spatha rubens 

 of the Encyc. Me"th. (Mai. Bl., 1866). This species is widespread, abundant, and 

 variable, and the material I have examined leads me to believe that it may include 

 either the short, rounded form of the Encyc. Me"th. or specimens that are more 

 elongated and even somewhat rhomboid. 



2 1 can not see any essential difference between this and forms of what I believe 

 are 5. rubens. I believe that the S. cailliaudi is only one of these forms. 



3 1 have only seen the reprint of this paper, which begins with page 1.
