Type, 0. 4-punctata, Laich., from Europe. 



Mange. Europe ; Africa ; Asia. 



Body similar in both sexes, cylindrical ; head and underside more 

 or less pubescent. Head perpendicular, deeply inserted ; mandibles 

 very short, robust ; clypeus feebly emarginate ; eyes very large, 

 elongate, placed obliquely, very slightly notched ; antennae short, 

 basal joint short and thick, succeeding two joints small, the rest 

 strongly triangularly widened. Thorax of variable shape, generally 

 strongly transverse and narrowed in front, posterior angles 

 rounded. Elytra without produced lateral lobes. Legs short, 

 anterior coxa? narrowly divided ; tarsi robust, broad, first and 

 second joints widened, equal or subequal. Last abdominal segment 

 of male with a smooth space at middle in many species, in female 

 with a small fovea. Pygidium not exposed. 



These characters apply more accurately to the European than to 

 the exotic species, which often show such a gradual divergence from 

 the typical forms that it is a matter of opinion as to the genera in 

 which they should be placed, no hard and fast rule being possible 

 for their classification. 



The principal charactera, viz., the absence of distinct lateral 

 elytral lobes, covered pygidium and the short tarsi, will assist in 

 the recognition of the genus. 



The larva? of this and other species of Clytritice construct a light 

 but tough cocoon which they carry about with them and only exsert 

 the anterior portion of then* body out of this covering.
