Vigo, Posey and Jackson counties ; scarce. Occurs especially on 

 maple trees infested with plant lice. ]May 20-.July S. Casey calls it 

 basalts ]Melsh. The two names were proposed by ^Melsheimer at the 

 same time, i-punciata on page 178. and hasalis on page 179, the 

 former therefore having priority.
