Found in the larva ftate in May and June, appears on the wing in 
Auguft. The fpecies is well diitinguifhed by the charaéter-like fufcous 
mark in the middle of the anterior wings, a kind of double mark, 
formed by the junction of two fubquadrangular fpots that unite toge- 
ther at their moft contiguous angle, being a little oblique from each 
other. Some compare this mark to the Hebrew character 3, but 
it does not well agree with this; the fimple appellation of double 
{quare {pot is much more applicable.
