(Cercus ferrugineus, Dej. Cat. 137, ed. 1837.) 
Fuscus testaceusve, cinereo pubescens, dense subtilius punctatus; prothorace lateribus 
subangulato. Long. 1-1} lin., lat. 4 lin. 
Habitat in Europa. 
Usually clear rust-colour, but sometimes darker, finely and closely pubescent, mode- 
rately densely and finely punctate. Antennze with the club in the females two-jointed. 
The thorax with the sides somewhat angularly expanded in the middle. The eyes, breast, 
and abdomen black. The elytra long, and most convex a little past the middle. Scutel- 
Ium rounded at the apex. 
Distinguished from its allied species by the slightly angular sides of the thorax and 
the fine punctation. 
Found on the flowers of Sambucus racemosus in spring in most parts of Europe. Not 
found in England. 
6. CERCUS LONGIPENNIS (Motsch.). 
Leviter punctatus, ferrugineo-testaceus, cinereo pubescens, elytris flavis ; prothorace trans- 
verso, lateribus rotundatis; elytris prothorace fere triplo longioribus. Long. $ lin. 
lat. 1 lin. 
Habitat in Dauria meridionali. 
Allied to C. Sambuci, but smaller and of finer punctation, and less pubescent. The 
elytra comparatively a little longer, and the thorax not so angular in the middle. Reddish 
yellow, with paler elytra. I received a single specimen from Count Motschulsky, from 
Southern Dauria, which I have placed in the British Museum.
