Sp. 5. Rap£E. Obion go-ovata, atro-cyanea, antennarum basi pedibusque testaceis,

Ha. Rapa?. lUiger.—Steph. Catal. 217. No. 2219. 



Oblong-ovate, convex, deep-Z»ke; beneath of a darker hue : thorax rather finely 

 punctured: elytra regularly ^wactate-striate, the interstices smooth: four 

 anterior legs, and the tibiie and tarsi of the posterior testaceous; posterior- 

 femora black with the base rufescent, or rufous with the apex black : an- 

 tennae fuscous, with the base testaceous. 



The dissimilarity in the colour of the insect and of its hinder femora, exclusively 

 of the diversity of its form, and the deficiency of punctures in the interstices 

 of the strise on the elytra, sufficiently point out the distinction of this insect 

 from the preceding, with which Gyllenhal considers it synonymous. 



Occasionally found near the metropolis.
