shallow foveate punctures. The interspaces very shining, 

 slightly elevated, and with rows of erect yellow bristles. 

 Body beneath coarsely foveate. Rostrum coarsely punctured. 

 Total length .16 inch=4 mm. 



One specimen. Batavia Junction, near Cincinnati, Ohio, 

 July 31, 1900. 1 found this curious little insect while sifting 

 some debris taken from a cavity at the roots of a large oak 

 tree. A spring of cold water flowed out, and the honey- 

 combed center of the tree was occupied by a nest of ants 

 {Formica pennsylvanica), so I suspect that the species is 

 myrmecophilous. A careful search has so far failed to reveal 

 other specimens.
