EURTCUS. 



Ilarycns cressida (Fabr.). 



I cannot agree with Dr. Jordan that the Eurycus from the S. West and 

 neighbouring islands are identical with E. cressida cressida from Australia. The 

 $$ as a rule are considerably larger and more diaphanous while the outer \ of 

 hindwings is paler and less scaled.

DiEfers from c. cressida chiefly in the $. $ more diaphanous, generally

Eurycus cressida intermedius subsp. nov. 



Differs from both c. troilus and c. cressida, but nearer the former, especially 

 in the ?. <S almost identical with c. cressida. ?. Above similar to c. troilus ?, 

 but the discal white patches on the hindwing larger ; below has the white 

 marginal spots of c. cressida.
