The characters given for the diagnosis of the Homceoceraria 

 are the principal points in the distinction of this large and 

 variable genus, which is not only the type of the Division but by 

 far its largest constituent. A number of generic divisions have 

 from time to time been proposed, as may he seen by the synonymy; 

 but by general consent these have been considei-ed untenable, for 

 though applicable to some small groups of species, they break down 

 when used for others which are decidedly connecting-links bet\Aeen 

 the sections. The same difficulty is found in making sectional 

 divisions of the species. The comparative lengths of the third and 

 fourth joints of the rostrum undoubtedly create two sectional 

 characters ; but beyond this I have been unable to formulate an 

 analytical synopsis. There is a gradual transition from species 

 having the pronotal angles well developed, with long and slender 

 antennae, to others in which those angles are not prominent, 

 combined with much shorter antennae, the last joint of A^'hich 

 tends to become shortened and thickened ; the body also, from 

 being elongate and straight, approaches a shorter and more 

 laterally dilated formation. 



The genus is concentrated in the Oriental Region, is fairly repre- 

 sented in the Ethiopian Region, and just enters the Palsearctic 

 Region in China and Japan, and again in Sind.
