328 MODERN CLASSIFICATION OF INSECTS. 



or subapocl larvse, and pseudotetraraerous tarsi, which exist in the 

 Rhyncophora and Longicornes. The precise links, therefore, by which 

 the passage between these two groups is effected, still remain to 

 be discovered. How far this may be effected by some of the smaller 

 Longicornes with pilose bodies, such as Mesosa Curculionoides, re- 

 mains to be ascertained. M. Chevrolat has shown me a remarkable An- 

 thribideous species from Brazil, which he has named Pseudolamia scopi- 

 cornis, which, as both names indicate, singularl}^ resembles someLamioe. 

 This subsection corresponds with the Linnaean genera Bruchus, At- 

 telabus, and Curculio, and is divided by Latreille into two primary 

 sections — first, those with the labrum distinct, the rostrum short, broad, 

 and flat, and the palpi filiform, (G. Bruchus) ; and second, those with the 

 labrum not apparent, the head produced into a more evident snout, and 

 the palpi minute and conical — (G. Attelabus and Curculio X.) Mr. 

 Stephens has adopted these two divisions, giving to them the family 

 names of Bruchidae and Curculionidos ; but Schonherr, the indefatigable 

 monographer of this difficult tribe of insects, has adopted a different 

 mode of distribution in his Genera ct Sjjecies Curci/lio7iidum, now in 

 course of publication, and in the first volume of which the following 

 classification is proposed: — 



Ordo 1. OiiTHocERi. Antennaj not elbowed; the basal joint not vei-y much 

 elongated; and the rostrum without a lateral canal for the reception of the basal 

 joint of the antenna?, comprising twelve divisions * : — Bruchides, Antliribides, 

 Camarotides, Attelabides, Rhinomacerides, Ithycerides, Apionides, Rhamphides, 

 Brenthides, Cylades, Ulocerides, and Oxyrhynchides. 



Ordo 2. GoNATOCERi. Antenn£e geniculated ; the basal joint elongated and in- 

 serted in an elongated canal at the side of the rostrum. 



Legio 1. Brachyrhynchi (Curculiones Fahr.) Rostrum short and thick, with the 

 antennae inserted near its extremity, comprising ten divisions : — Brachycerides, 

 Entimides, Pachyrhynchides, Brachyderides, Cleonides, Molytides, Brysopsides, 

 Phyllobides, Cyclomides, Otiorhynchides. 



Legio 2. Mecorhynchi ( Rhyncha^nides Fair.). Rostrum cylindric or fdiform, 

 more or less elongated, seldom shorter than the thorax ; antennas inserted be- 

 tween the base and the middle of the rostrum, and not at the tips, comprising eight 

 divisions : — Erirhinides, Cholides, Cryptorhynchides, Cionides, Rhyncophorides 

 (Calandra, &c. ), Conoderides, Cossonides, and Dryopthorides. 



By this arrangement the Linnaean Attelabi, and some few of his 

 Curculiones, are united vtith his Bruchi so as to leave his genus 

 Curculio nearly in its original extent, which latter cannot but be re- 

 garded as an advantageous step. 



* These divisions appear to be of a lower rank than those which I have regarded 

 as subfamilies in the Carabida;, &c., having a similar termination in ides.
