" 176. Aiiar Leptogaster carolinensis, strike out Tab. XII, fig. 71, in the 

 synonymy; the note should read thus: Z. ?m"<«?;/s Macquart quotes 

 Tab. XII, fig. 7; the comparison however of this figure with the 

 descriptions of O. nitidus and G. Audouinii in the letter-press 

 shows, that the figure refers to the latter species. The name ni- 

 tidus must be dropped, having been used before; the name gigas, 

 engraved on the plate, instead of Audouinii, must be erased. The 

 passage in Linn. Entom. II, p. 395, proposing to adopt the name 

 gigas for nitidus, Avas written before Macquart's mistake in the 

 quotation of the figure had been discovered. Schiner was there- 

 fore right in proposing a new name for the species.
