 These curious little noctuids dance up and down in stationary 

 groups of usually two to four at twilight, in open sandy 

 ground, near the level of the tops of plants. The subcostal 

 and discal cells of the male fore wings are greatly enlarged, 

 transversely ribbed, and usually denuded. While they are 

 dancing, a continuous rapid series of sharp ticks is heard, 

 exactly like that of a watchman's rattle, but of diminutive 

 volume, yet easih' heard fifty feet away. This is probably 

 effected by the male's extending the fore legs and rasping 

 the tibial spurs against the corrugated cell-membranes during 

 llight. Urbana, Au. 28 and S. 29, in gravel-cut on railroad.

Olethreittes dimldiana Sodoff? (U. S. Bur. Ent., det.). H.l, 2; 

 Je. 7, 8 (all immature). In these two localities many cylin- 

 drical tubes of webbed sand were found extending up the 

 stems of Onagra biennis, Cassia cka»iceci'ista,a,nd Ambrosiai '?) , 

 often as much as two feet long, and following most of the stems 

 of a plant, reaching the top, where the new growth had been 

 fed upon. In one case a short tube was formed on the surface 

 of the bare sand. These tubes closely resemble those figured
