Victus Harpalorum, 



Apparently closely allied to Amblystomus, — differing, however, 

 in the sculpture of the tarsi, and in the antennre, labrum, and palpi; 

 and, as in the diagnosis as given by Lacordaire in his ' Gen. des 

 Col.,' the paraglossse of Amblystomus are simply said to be 

 rounded in front, a further distinction woidd appear to reside 

 in the notch which exists in that part of the paraglossse of my 

 genus Megaristerus. Also allied to Acupalpics, the sculpture of 

 the tarsi being exactly the same, — in saying which, I bear parti- 

 cularly in mind that the intermediate ones of the male are hardly 

 ddated. From this genus, however, it is effectually distin- 

 guished by the shape of the ligula. From both Amblystomus 

 and Acupalpus the present genus, moreover, differs in the vesture 

 of the four anterior tarsi of the male, the first joint being nuked 

 below — and in the mandibles, the left one of which is much larger
