type of Anthohoscus. Lastly, Xylotrcchis (p. 190) is 

 again reduced to its original dimensions, with X. Sartorn 

 for its type, as defined by Clievrolat in 18(30. 



It is not very clear, even now, where Mr. Thomson 

 draws the line between Clytus and Glytantlius. Europa, 

 Thoms., is given as a synonym of Clytus, and Anthohoscus, 

 Chevr., as a synonym of Clytanthus. But this cannot 

 be more than approximately true ; Europa included an- 

 nularis, the type of Chlorophorus, which is merged in 

 Clytanthus j and there are various species — e. g., ornatus 

 and pleheius — -placed by Thomson in Europa, which by 

 Chevrolat were placed in Anthohoscus. I understand 

 Clytus (Thoms. 18G1) to include the whole of Europa 

 (Thoms. 1860), with the exception of Chlorophorus (Chev, 

 I860) . If this be not Mr. Thomson's meaning, he has 

 omitted to show which of the species of his Europa belong 

 to Clytus and which to Clytanthus. 



At the risk of a little repetition, I will exhibit in a 

 tabular form the changes in generic nomenclature made 

 by the above-mentioned authors within a period -of five 

 years, as they afi'ect the half-dozen species which have so 

 long been known by the names given in the left-hand 

 column : —
