Trictenotomida?. 
Lacohdatre (Gen. Col. viii. p. 2) discusses the systematic position of these 
insects, which he regards as presenting no character, except their hetero- 
merous tarsi, to separate them from the Prionides among the Longicornia. 
He divides them into the 2 genera Autocrates (J. Thoms.) and Trictenotoma 
(Gray). 
Longicornia. 
The eighth volume of Lacordaire’s admirable ^ Genera des 
Coleopteres’ contains the first portion of his classification of 
the Longicornia. His system presents none of that originality 
which rendered the volumes on Curculionidae so remarkable, the 
general principles of the classification of the Longicorn Beetles 
being already well established. It will be useful, however, to 
indicate the subordinate classification here, with references to 
the pages, as the number of groups is large. The table of sub- 
families given by Lacordaire (p. 16) is as follows : — 
I. Last joint of palpi not aciculate ; anterior tibiae with no oblique internal 
furrow. 
A. Ligula corneous; pronotum distinct from the sides of the pro thorax; 
anterior coxae strongly transverse Prionides. 
13. Ligula generally membranous ; pronotum very rarely distinct from 
the sides of the prothorax ; anterior coxae very variable. 
C6ramhycides. 
II. Last joint of palpi aciculate ; anterior tibiae with an internal oblique 
furrow Lamiides. 
The Prionides are divided into two Legions : — 
Legion I. PRIONIDES ABERRANTS (p. 19). 
Tribes : Parandrides (p. 21), Erichsoniides (p. 23), Anoplodermides (p. 25), 
llypoc6pholides (p. 28), CanUiarocn6mides (p. 31), and Sc6l6ocanthides (p. 34), 
Legion II. PRIONIDES VRAIS (p. 35). 
Cohorte 1. Prionides vrais souterrains. Groups : Psalidocoptides 
(p. 38), Psalidognathides (p. 39), Micropsalides (p. 42), Polyarthrides (p. 44), 
Merosc6lisides (p. 46), and Cyrtognathides (p. 50).

Prionides vrais (p. 59), Catypnides (p. 02), Cacoscdlides (p. 63), IToplidSrides 
(ip. G6), Acanthophorides (p. 68), D&ohrachides (p. 71), Enoplocdrides (p. 74),

(p. 81), Aulacocerides (p. 84), Ctenoscelides (p. 86), Callipogonides (p. 91), 
Ergatides (p. 93), Macrotomides (p. 98), Aulacopides (p. 101), Remphanides 
(p. 103), Mallodontides (p. 122), Zaracides (p. 131), Colpoderides (p. 133), 
Orthosomides (p. 140), Closterides (p. 149), AEgosomides (p. 153), Monodes-
