joints of antennal fuuicle, the seventh joint being twice the 

 thickness of second." (Dictz.) A series of curtns collected in 

 Virginia and Maryland in June, seems to indicate a possibility 

 that nioidicus may prove merely a southern race of that species. 



V. AULEUTES Dietz, 1806. (Gr., "sulcate.") 



Small robust forms, rarely over 3 mm. in length, having the 

 beak rather stout, cylindrical, feebly curved; eyes with elevated 

 orbital margin, partly or wholly concealed in repose; thorax with 

 distinct lateral tubercles; pectoral groove deep, usually extend- 

 ing upon the metasterunm. They are dark colored insects, thinly 

 clothed with a fine scale-like pubescence and mainly separated 

 from Coc-Hodcs, with which they were formerly grouped, by the 

 short second ventral and the grooved unarmed femora.
