The caterpillars are gregarious at first, but during the later part 
of their life separate. The cocoon is made in the ground. The 
insect occurs from New Jersey and southern Pennsylvania south¬ 
ward in the Appalachian region at comparatively low elevations.

This is another family which is represented in our fauna only 
by a small number of species. Besides the insect known as 
Dalcerides ingenita Henry Edwards, there is only one other 
species referable to the family known to occur within the Unite-l 
States. This insect is Pinconia coa Schaus, a moth which is 
not uncommon in Mexico, and occurs in Arizona as a straggler 
into our territory. Dalcerides ingenita is likewise an inhabitant
