Ne. violacea. Olivier. — Steph. Catal. 131. No. 1406. 



Deep violet blue, or blue-green ; villose : antennae black : thorax very thickly- 

 punctate : elytra rather deeply punctate, the punctures disposed in rows : body 

 beneath obscure deep blue : legs nearly of the same hue. 



Colour and size very variable: the broad truncate club of the antennas distin- 

 guishes this insect from Corynetes violacea, which it greatly resembles. 



Far from uncommon in dried bones, in dead carcasses, and skins, 

 throughout the metropolitan district. " Glanville's Wootton." —

* Every entomologist must rejoice at tbe propensity of this insect to frequent 

 prisons, as they owe the preservation of the life of the celebrated Latreille to the 

 appearance of one of these insects during his incarceration, at the period of the 

 revolutionary troubles in France, thirty years since, as fully detailed by him in 

 his Histoire Naturelle des Crust., &c.
