Antennae robust, shorter than half the body, subincrassate, three or 

 four basal joints fulvous ; head and thorax finely punctured ; scutellum 

 broad, more or less stained with piceous ; eljiira scarcely broader than 

 the thorax, deeply punctured, the punctures on the inner disk indi- 

 stinctly arranged in numerous longitudinal strife. 



Fam. Gallerucidae. 



Genus Diamphidia, Gerst. 

 Cladocera, Hope. 

 The insects known and described by Hope, Gerstaecker, and others, 

 under the above generic names, appear to form a single natm-al 

 genus, the species varying greatly in the degree of sensation or even 

 flabellation of the antennae, but agreeing in all their other characters. 

 I would divide the genus into three sections, formed on the degree of 

 variation of those organs. 



Sectio I. Antennis flabellatis in utroque sexu. 



II. Antennis serratis aut subserratis in uno aut utroque 



sexu. 

 III. Antennis simplicibus. 

 Cladocera of Hope having been already used, Gerstaecker's name, 

 Diamphidia, must be adopted ; but from these authors having founded 

 their genera on the extreme states of the antennae, either term is 

 characteristic only of a certain number of species in the genus.
