490 CLASS VIII. 



Family LII. Stenelytra. Body with very few exceptions 

 winged. Maxillae with internal process mostly unarmed. Mandibles 

 terminated by apex simple in some, in others bifid. Antennae fili- 

 form, in many longer than thorax and head together, in few only 

 sub-perfoliate. Penultimate joint of tarsi often bilobed. 



Narrow-shielded. This denomination is not appropriate for all 

 the species, and this family of LATKEILLB, in fact, is neither very 

 natural nor sharply defined ; we retain it only because unwilling to 

 multiply too largely the number of families in our concise revision. 

 The larvse have six feet, but differ in other respects in the different 

 genera of this division. They live under the bark of trees or in 

 decaying wood.
