280 THE ENTOMOLOGIST. 
a. Oral organs normal. Club of 
- antenne annulated; third 
joint of tarsi bilobed. 
Mesothoracic epimera not ascending. 
Mesothoracic epimera ascending. 
b. Oral organs abnormal ; first joint 
of antennal club usually very 
large, corneous; third joint 
of tarsi rarely bilobed. 
Pygidium exposed. 
Pygidium covered by elytra. 
Each of these divisions contains several tribes differentiated 
by characters of smaller importance, and not unfrequently 
indefinite. 
III. The next attempt at a general classification was made 
by Mr. H. Jekel.* This excellent author recognized with 
great clearness, and defined with tolerable precision, the 
following eight principal types. among the Rhynchophora:— 
Bruchides, Anthribides, Attelabides, Curculionides, Calan- 
drides, Cossonides, Scolytides, and Brenthides. The last- 
cited memoir is occupied chiefly with a further development 
of the classification of the largest of these, the Curculionides 
proper ; and in it he proceeds to separate, as sub-families,t— 
Brachycerides, Brysopides, and Amycterides: epigeal forms, 
in which the tarsi are not dilated, and not furnished with 
brush-like hairs beneath. Having thus isolated them, the 
great mass remaining is divided into— 
Body dissimilar in form, male and female ; narrower 
in male. - - - : - PLATYGNES. 
Beak similar in both sexes. - - - Homorhines. 
Beak dissimilar. - - - -  Jeterorhines. 
Body nearly or quite of the same form, male and 
female. 
Pygidium covered by the elas body Pe 
or pubescent. - Iso@ynEs. 
Pygidium exposed or covered ; ; body squa- 
mose, &e. - - - - METRIOGYNEs. 
* Annales Ent. Soc. France, 1864, p. 537; Ins. Saundersiana, 155 sqq., 
+ Mr. Jekel gives to the auomalous groups this subordinate position, 
rather, as he says, ‘* Pour ne pas heurter Jes idées généralement admises,” 
than in accordance with his own views, which would lead him to regard them 
as I have done,—as genuine families,
