mesonotum is large, usually convex, tricarinate, with the suture 

 separating- its posterior sclerite, or scutellum from the anterior, 

 more or less distinct. The elytra vary from membranous to 

 coriaceous or nearly so ; ordinarily they are folded roof-like when 

 at rest but may be either vertical or nearly horizontal; they 

 may be narrowed to a strap-like piece or very broad and 

 rounded, and in venation they vary from the simplest form to 

 the most complex; they are often short and the same species may 

 show two or more distinct variations in this particular. The wings 

 may be much aborted or entirely wanting even in forms with fully 

 developed elytra and the same species may be apterous or fully

winged. The antennae usually have two segments and a terminal 

 seta and these segments may be terete, flattened or greatly 

 expanded, or the second may be split to its base into two or more 

 filaments. The ocelli are ordinarily two, placed close to the eyes, 

 near their lower angle, but there may be a third at the apex of 

 the front. The legs are frequently flattened and the hind tibiae 

 are usually two to five spined, and in one subfamily are furnished 

 with a movable spur at apex. 



Various attempts have been made to split this family up into 

 several families ; but in spite of form-diversity there is a certain 

 uniformity of character running through the whole group that 

 makes such a division undesirable, at least with our present knowl-
