208 APOGONIA METASTERNALIS. 



The elytra are covered with large aud deep punctures; 

 each elytron shows two very distinct narrow costae, the 

 third (originating from the outside of the shoulder) being 

 less distinct; along the sides are three rows of strong 

 punctures, and the narrow space by which they are sepa- 

 rated from the third costa bears on the basal half of the 

 elytra a single row of similar punctures ; the sutural in- 

 terstice shows a regular row of fine but very distinct 

 punctures; the costae, however, of which the second is 

 triangularly enlarged at the base, are impunctate; the 

 punctuation on the shoulders is obsolete. 



The propygidium is very densely and rugosely, the py- 

 gidium very coarsely punctured , the latter bears some 

 stiff hairs and shows a more or less distinct median keel. 



The punctures on the sides of the prosternum are ra- 

 ther wide apart, on the sides of the metasternum they 

 are close together, and on the abdomen they are the lar- 

 gest and pitlike , especially on the last segment. The ba- 

 sal segments of the abdomen are opaque. The anterior 

 tibiae have three teeth of which the upper one is obsolete. 



(ƒ. The middle of the metasternum raised, the raised 

 portion provided with a semicircular impression the open 

 side of which is turned backward; the four basal joints 

 of the tarsi thickened , those of the anterior pair broader. 



Q. The middle of the metasternum less raised, the im- 

 pression less distinct, the tarsi more slender.
