are so closely allied, that it seems hardly possible, any future 

 discovery shall disturb their proximity.

Scaphinotus elevatus Dejean, Spec. Gen. vol. ii. p. 17. 



Desc. Head black, very slightly tinged with violet, impunc- 

 tured : antennae brownish towards the tips : thorax black, 

 slightly tinged with violaceous, the sides gradually more reflected 

 to the hind angles, hardly contractly behind ; disk concave, with 

 small, numerous, irregular punctures ; base nearly as broad as 

 the base of the elytra ; basal angles prominent, acute : elytra 

 violaceous-cupreous, brilliant ; striae numerous, obtuse ; inter- 

 vening lines narrower than the strige, obtuse ; humeral edge 

 dilated, reflected, elevated and rounded : epipleura confluently 

 punctured : pectus with a few punctures at base ; lateral margin 

 with minute punctures : postpectus and venter, each side at base? 

 with large punctures. 



Obs. This species was supposed, by all the authors, previous to 

 Knoch, to be a native of South America, but that entomologist 

 determined its native country, by receiving specimens from the 

 late Dr. F. V. Melsheimer, of Hanover, Pennsylvania.

MELITiE[A]. Plate XLVI. 



Generic character. Antennae with a short, somewhat broad, 

 compressed terminal club ; palpi divaricating, hairy, second joint 

 compressed, terminal joint acicular, half the length of the pre- 

 ceding joint; inferior wings suborbicular, somewhat checkered 

 beneath ; anterior feet short, feeble ; tarsi with double nails. 



Obs. The distinction between this genus and Argynn is, is very 

 slight, too much so, we think, to justify the continuation of it, 

 except perhaps as a subgenus. We have set down the characters
