strongly scalloped than in ceratomioides. Hindwing : pale discal band narrower 



than the black liand separating it, from the subcentral patch. 



Undcrsiile : pale postdiscal band cif forewing as narrow as in i'cvatomioi(le<, but 

 straight. 



S . Both the tergite and steruite of the tenth abdominal segment longer and 

 narrower than in ceratomioidca ; the harpe more compressed and somewhat stronger 

 dentate ; left jirocess of penis-sheath broader than in the allied species.

^?. The large material of this species wliicli we have exan)ined e.\liibite.l 

 considerable variation. The more extreme individuals have been descrilied as 

 distinct species, and we admit that the dilferences are so obvious that one might 

 easily be induced to consider them of specific value. But the numerous si.ecimei- 

 which connect the extremes with one another show this conclusion to be mvalid. 



As in a'ratomiok/e.'i the external spur of the midfibia is somewhat shorter than 

 the internal one. Fresh specimens have a greenish tint. Abdomen wuh three
