I M. gasellnla ^ (as formerly identified), Canada, in my own col- 

 lection. 

 Both sexes are represented in the specimens of gihhiiliis and its syn- 

 • onyms. 



IMr. Morris states that he has seen a specimen of true gaccUiila 

 from Canada. Dr. Hamilton in his Catalogue of the Coleoptera of 

 Southwestern Pennsylvania says gazcUula is rare at Allegheny, Pa., 

 but common at St. Vincent, and Henry G. Klages in his supplement 

 thereto (Ann. Carn. Mus., I, 1901, p. 290) adds gihhulus "believed to 

 be a distinct species by Dr. Hamilton." It seems therefore impossible 

 to consider gazcllnla and gibbulus as geographic races of one species, 

 since there is evidence that their ranges overlap. 



The bibliography and synonymy should stand as follows :

I am not unaware that Aurivillius treats the genus Microclytus as 

 a synonym of Anaglyptns; but in this he stands opposed to all Amer- 

 ican authors, Leconte, Horn, Hamilton, Casey and Schaeffer, who has 

 quite recently (Journ. N. Y. Ent. Soc, XII, 1904, p. 223) given a key 

 to the genera of Anaglypti ; and his course cannot therefore be 

 adopted.
