1 The locality label of the 3 figured by Holland should be checked, as one is 
never safe with that author. McDunnough (1916 l.c.) was the first to point out 
that gyas could not be separated genitalically from antibubastus , and W. Com- 
stock (1943:109) noted that the latter was structurally identical with filenus.
