 1824, 273 ; ibid. II. 161. 

 Broader and more robust than mellyi. Head, thorax and under sur- 

 face tu~ elytra and legs pale brown, the latter often tmged with fus- 

 coas Zrax with median line usually obsolete or visible only on basa, 

 balf Otherwise as in mellyi. Length 8-10 mm. 



Throughout the State, frequent in the northern counties; much 

 less so southward. June 12-August 6. Occurs ^otuS 

 on foliage near water. Listed as hadnpenms Lec^ It » my op nion 

 that mdlyi will be found to be only a narrower, darker form of this 

 1" those examples of mellyi with slightly paler elytra forming 

 the intergrades. Say's name is the older of the two. 



Tribe II. PEDILINI. 

 Very neat, oblong or elongate black (rarely brown) beetles hav- 

 ing ^thorax usually yellow, subglobose and polished; mandiWes 

 truncate; antenna, (in our species) ^™^ S ^™^ 

 i«rv nalni feeblv dilated; next to last joint of tarsi bilobed lhe 

 ^hSe distinct ventral segments and often have the tips of 

 elytra impressed and polished, 



"The tribe is represented by the single genus Corp* g , fl£ 

 Casey ha, substituted for this the old name Peddus, but Horn has 

 grven (Trans. Ill, 278) good reasons why Say's name should stand, 

 so it is here retained. 



III. Corphyra Say. 1835. 

 Horn in his latest paper on Corphyra (loc cit.) lists 20 species 

 as belonging to the North American fauna. Dury has shown that 

 rnumbe'r of these are very closely related arid probab y ^nonyn> 

 ous The thorax in all species is elliptical with all the angles 

 "nded in the wholly black species it is somewhat wider and ess 

 convex than in the others. Eight of the 20 forms have been taken 

 in the State, while another may occur.
