'264 CRYPTOCEPHALINARUM BOREALI-AMERICAE DIAGNOSES. 



' The description of Fabricius requires only the basal articulation of the antenna to 

 be flavous. In one specimen this color extends to the fifth articulation. There is an 

 impressed marginal stria, and a short basal submarginal one. Middle and Southern 

 States. 



73. M. xTE-R].Knoch. (Clythra.) Niger, nitidus : labro et antennarum basi 

 flavescentibus : pronoto laevi, cyanescente : elytris indistincte seriatim punctulatis. 

 Long. 1^ lin. 



More robust than the preceding, with the elytral punctures less distinct. Southern.

 rufis : elytris distincte seriatim punctulatis. Long. 1 lin. 



The elytra are more distinctly punctured than in the two preceding species ; and 

 the two exterior striae are impressed, punctulate, and entire. The presternum will 

 doubtless be found indistinctly rufous, as there is some appearance of this color in the 

 individual characterized. Southern. 



75. M. APRiTcs Hold. Dej. ,449'. Cyaneus, nitidus: labro, clypeo, fronte, 

 antennis, pedibus, prosterno, pronoti lateribusque^ay?^ ; pronoto impunctato; elytris 

 distincte seriatim punctulatis. Long. I lin. 



The individual characterized is Southern. 



*,*In the preceding pages a coro/na point between two numbers, indicates volume and page ; a minute 

 mark (') plate dtnd Jigure ; and a colon the number of species in an author's list. See p. 260, No. 59. 

 The mark | indicates uncharaderized. 



In the following Index, the numbers refer to the order of the species in the preceding pages ; the 

 parenthesis marks a synonym; the smaller letter next the number, the genus, and when placed next the 

 authority, it indicates the genus according to that authority. This notation is intended chiefly for 

 alphabetical catalogues, which should contain, in addition, a reference and a notation for locality.
