DESCRIPTIONS OF NEW SPECIES. 1*9 



of Enoplium as given by Duval and Ciesenwetter. Duval has 

 observed* that the ungues of E. i-punctalum arc acutely toothed 

 at the base, while those of the European species are simple. I 

 find that they are broadly and slightly dilated at the base in the 

 former, but can hardly be called toothed : in E. scabripennis they 

 are very feebly dilated, while in the Texan E. i-notatum the 

 dilatation is scarcely perceptible.

Found in the Smithsonian grounds. Washington, I>. 0., by Mr. 

 Ulke, under the bark of a coniferous tree. The antenna' extend 

 as far as the lateral angle of the prothorax. This inseel re- 

 sembles in form and general appearance Derodontua maculatua 

 30 much that it might without examination be readily taken for 

 a dark colored variety of that Bpecies.
