CARABID^l. AMARA . 



appearance, then straight, posterior angles very little produced, 

 with the tip itself obtuse, disk convex, very smooth and shining, 

 the dorsal'furrow very slender, the base with two obsolete fovese 

 on each side and a transverse indistinct impression at the base 

 of the dorsal furrow. Elytra in front as broad as the thorax, 

 ovate, sinuated a little at the apex, striated, the stride impunctate, 

 but deeper at the extremity; legs black, tibise and tarsi with red 

 cilia. Length 4i lines. 



Fabricius described an unusual variety of this insect (probably 

 immature) under the name ovatus, having a brownish body and 

 red legs. A. obsoleta, Dej., presents the typical characters of 

 the species. A. ingenua, sub&nea and lata of the Stephensian 

 collection belong to the present species. 



Generally distributed, but not very abundant.
