Similar in form and coloration to F. tovteutosa, Lac, it is, 

 however, very distinct from that species, and may at once be 

 known by its entirely glaln-ous elytra, and also by the punctures 

 on their surface being arranged in irregular strife. Face concave 

 between the eyes, the latter distinctly notched, surface finely ))Ut 

 distinctly punctured, vertex granulose ; clypeus not separated 

 from the face by a sutural line, its surface oljhquely deflexed, 

 smooth, impunctate, the anterior border deejjly angulate- 

 emargiuate. Thorax twice as broad as long at the liase, basal 

 lobe refiexed, obtusely truncate; sides rounded and narrowed 

 fi-om liase to apex, more (puckly con^-erging towards the latter.
