Penthini is represented by Penihe with two species. 



Synchroini, Synchroa with one species. 



Mallodryini is instituted for a new genus, Mallodrya, with one 

 species, with which I am at present inclined to associate Sphalma 

 quadricollis, formerly placed in the Pythidie. 



Orohesiini remains the same as in the Classification, with the 

 addition of Holodrophus formed by the division of Endroplms. 



Melandryini by the removal of certain disturbing elements for- 

 merly considered as subordinate groups, the Melandryini form a very 

 homogeneous central series in the family. With an increase of spe- 

 cies it is not quite so easy to subdivide the tribe into subordinate 

 groups, but there are three fairly indicated groups illustrated by 

 Melandrya, Serrop(dpus and Hypidu.s. 



Scraptiini remains as at present constituted. 



Mycterini is unchanged. 



NoTHiNi contain the genus Notkm alone. There is not perfect 

 accord as to the name. Osphya, often used is merely a name men- 

 tioned in a foot note. Four years later Olivier gave the name Nothiis 

 with a description sufficient at the time, and I think, with Lacordaire, 

 that the name should be adojited.
