388 CLASSIFICATION OF THE RHTNCHOPHOROUS COLEOPTERA. 



principal tj-pes among the Rhj-nchopliora : Bruchides, Anthri- 

 bides, Attelabides, Curcnlionides, Calandrides, Cossonides, Sco- 

 lytides and Bienthides. Tiie last cited memoir is occupied chiefly 

 with a further development of the classification of the largest of 

 these, the Curcnlionides proper, and in it he proceeds to separate 

 as sub-families* Brachycerides, Byrsopides and Amy cter ides, 

 epigeal forms in which the tarsi are not dilated, and not furnished 

 with brush-like hairs beneath. Having thus isolated them the 

 sreat mass remaining is divided into 



Body tlisshuilar iu form (J, $, narrower in (J .... Platygnes. 



Beak similar in both sexes Ilomorhines. 



Beak dissimilar Hcterorhines. 



Body nearly or quite of the same form $ $ : 



Pygidium covered by the elytra, body poUiuose or pubescent 



ISOGYNES. 



Pygidium exposed or covered ; body squamose, etc. Metriogynes. 



Pygidium covered Crtjptopyges. 



Pygidium exposed Gymnopyges. 



The principal types contained in each of these three grand 

 divisions are then characterized in a very clear manner ; but for 

 a proper understanding of this system, a vast improvement on 

 all that preceded, the reader must refer to the original memoir. 

 In developing the arrangement of the tribes represented in our 

 fauna, I shall be largely indebted to the views expressed in this 

 most valuable memoir of Mr. Jekel. 



There remain to be mentioned two faunal contributions to the 

 histoiy of this subject : 



1. A series of remarks b}' Mr. Suffrian,-}- in which the German 

 species of several genera, not before carefull}^ studied, are more 

 fully elucidated, and various criticisms upon Schonherr's system 

 made. J The necessity of a more careful study of the tibia3 and 

 tarsi, almost neglected by Schonherr is insisted on, and an arrange- 

 ment of the German genera in groups upon these characters is 

 given. 



2. That most admirable work of Prof. C. G. Thomson, § to 



* Mr. Jekel gives to the anomalous groups this subordinate position, rather, as he 

 says "pour ne pas heurter les ideos generalenient aclniises." than in accordance with 

 his own views, which would lead him to regard them as I have done, as genuine 

 families.
