D The elytra coarsely, closely, and irregularly punctured. 



pulicarius Zimm. Page 99. 

 DD The elytra punctured in rows. 



E The pronotal asperities distinctly separated. 



F The declivity with the suture strongly elevated and the 

 elytra individually, deeply sulcate; the dechvity without 

 granules. lautus Eichh. 



FF The declivity with the suture moderately elevated, much 

 less so than the sides, and the elytra therefore con- 

 jointly broadly sulcate, not so deeply as in EE; the 

 suture and sides on the declivity granulate. 



rhois Sw. Page 99. 



EE The pronotal asperities united to form perfectly concentric 

 semicircular ridges; the declivity with the elytra con- 

 jointly, deeply sulcate, the suture only very feebly elevated. 



F The elytral interspaces sparsely punctured near the 

 suture; the front margin of the pronotum strongly 

 asperate at the middle only, the declivity not granulate. 

 Key West, Fla. lateralis Sw. 



FF The etytral interspaces impunctate, the front margin of 

 the pronotum feebly asperate throughout; the suture 

 and the sides distinctly granulate on the declivity. 



concentralis Eichh. Page 104. 



CC The declivity only very feebly sulcate along the suture; interspace 

 2 feebly punctured; punctures of striae 1 and 2 distinct but smaller 

 than on the disc; the suture rather well elevated but smooth or 

 nearly so; the elytra stout, one-half longer than the pronotum; 

 minute species. 



D The pronotum rather narrowly rounded and distinctly serrate 

 on the front margin; the pronotum and elytra strongly punc- 

 tured, puberulus Lee. Page 99. 



DD The pronotum very broadly rounded and only obsoletely serrate 

 on the front margin; the elytra very feebly punctured. 



opaculus Lee. Page 99. 



BB The elytral declivity with the punctures of strise 1 and 2 becoming 

 much smaller or nearly obsolete, with interspace 2 decidedly sulcate, 

 shining, and usually distinctly wider than on the disc (PL 16, fig. 4). 



C The declivity not acuminate at the apex, usuallj^ rather broadly 

 rounded, with the suture narrow and feebly elevated (PI. 16, fig. 8). 



D The pronotum moderately or narrowly rounded in front and 

 distinctly serrate; the declivity rather broadly rounded; the 

 elytral interspaces with the punctures rather numerous. 



E Rather slender species with the elytral punctures usually 

 small and those of the interspaces usually moderately 

 numerous; the female front clothed with very long yellow 

 hairs, the male front with a well-developed transverse 

 median carina, the vertical carina usually nearly obsolete. 



F The declivital sulcus wide and shallow, with the lateral 

 granules coarse or nearly obsolete.
