Mr. Kirby on Herbst's Genus Apioiu 67 



lineola dorsali, postice impression, longitudinalitcr exa- 

 ratus. Scutellum minutissimum. Coleoptra ex ohlongo 

 obovata, caerulea aut viridescentia, nitidiuscula, stri- 

 ata : striis punctatis ; interstitiis planiusculis. 

 This insect is nearly related to the preceding species, but the 

 rostrum is shorter in proportion ; the thorax, instead of an im- 

 pressed point, has a longitudinal furrow ; the elytra of the male 

 are blue, and those of the female green ; the furrows also of the 

 elytra are more lightly drawn, with flat interstices. When I 

 originally sent this species to Mr. Marsh am, I had observed it 

 only upon water dock ; I have since taken it, and more plenti- 

 fully, upon the common dock, so that perhaps its trivial name 

 might better be Apion Lapathorum.
