and Central Arnerican Telephorinae. 137 



inserted near the inner margin of the eyes, long, slender, similar 

 in the two sexes, joint 2 short; prothorax narrow, subquadrate ; 

 elytra abbreviated, obliquely attenuate ; penultimate dorsal seg- 

 ment of abdomen truncate or broadly emarginate behind, leaving a 

 small terminal segment exposed, the latter bidentate in (J; legs 

 slender; tarsal claws toothed at the base; genital armature of <J 

 asymmetric. 



Type, Malthinus major, Gorh. 



This genus includes Malthinus major and M. championi, 

 Gorh., both of which may be at once separated from 

 Malthinus by the stout palpi. The rapidly and obliquely 

 narrowed head, the very short second antennal joint, the 

 feebly developed prothorax, and the slender legs, dis- 

 tinguish. Pseudolobetus from Trypherus, Lee. (type Malthinus 

 latipennis, Germ.); and the simple antennae, toothed 

 mandibles, and basally toothed tarsal claws separate it 

 from Lobetus, Kies.
