GEXOTYPE, Oplrion untritor, F. 



Head a little constricted behind the eyes, with the vertex not 

 smooth ; frons usually transversely elevated ; cheeks not very 

 short ; face strongly transverse. Antenna? of $ with at least 

 twenty flagellar joints, of which the first is generally longer than 

 the second, and not or hardly transverse. Thoracic notauli short 

 but distinct ; metanotum with the basal area not short and very 

 rarely with a basal carina : sternauli always distinct, though 

 occasionally abbreviated. Abdomen with the second segment 

 longer than broad, and the first not often strongly convex ; 

 terebra exserted and usually elongate ; thyridii elongately trian- 

 gular. Calcaria not very small. AVings with the lower angle of 

 the brachial cell entire ; apical abscissa of radius not deflexed, 

 and always at least twice the length of the basal. 



Range. Europe, Assam. 



No example of this genus has hitherto been noticed outside 

 Europe, for which the inconspicuous size of its species probably 

 accounts.
