Dlstrihution. Almost uuiversal. 



Cydnus and jEtlms have been treated as separate genera by 

 most writers, but it seems best to unite tbem, as has recently been 

 done in Lethierry and Severin's Catalogue. The antennae are 

 live-jointed ; body oval or ovate, slightly concave; margins of the 

 head pilose, setose, or remotely ciliated ; lobes of the head equal 

 in length, or the lateral lobes longer than the central lobe; ostiolar 

 canal having either at the apex a tree lobe, more or less elevated, 

 horn-shaped, and more or less flattened at the sides (Cychms, 

 Sign.), or without this appendage {^tJius, Sign.).

 either side of the apex of the central lobe ; antennae piceous, apex 

 of the terminal joint pale brown ; eyes reddish or bro\\nish-red ; 

 rostrum piceous ; pronotum shining ; anterior margin ■\^•ith four 

 foveje, placed two on either side, between the two inner are a few 

 punctures in a curved line, lateral and posterior margins rather 

 broadly but finely punctured, across the disk are four somewhat 

 obscure fovea^, the two exterior most pronounced, apex depressed ; 

 scutellum coarsely punctate ; corium much more finely punctate;
