166. Larva. Front leg. 167. Case. 
In the Ithaca region the larve make cases of sand grains in 
the form of curved cornucopias, figure 167, without lateral flanges, 
and without decided hood-like covers on the cephalic ends. In 
cross-section the cases are cylindrical. 
The cases of the material from Wisconsin have decided lateral 
flanges, and have well-developed hoods that completely cover the 
larve’s heads.
