The type in the British Museum is a poor, crushed female, closely 

 allied to algens, but much darker basally. It is not impossible that it 

 may prove a suffused form of Mr. Grote's species, but it will need more 

 material than I have seen to decide. Mr. Butler places it in Bieojns, 

 evidently without reference to the essential characters of that genus.
