wood, adjacent to the university campus at Gainesville, badly infested 

 by a bark borer, produced only gelijormis instead of scitiila which had 

 been expected. The much-abused tree trunk of a hickory gave the same 

 results. From Andricus galls on oak at Monticello both gelijormis and 

 scitula emerged. Several examples in the United States National 

 Museum collection bear this label : "Cocoa, Fla., April 28, 1939. Larvae 

 in callus tissue formed where rabbits had gnawed the bark of Australian 

 pine, Casiiarina equiseti folia, A. S. Rhoads, collector." 



The moths are most numerous in March and April but continue to 

 issue until July.
