prevalent in that region. So far as the evidence of Mr. Peel's 

 collection goes, the reverse is the case. Another remarkable fact 

 in the distribution of these parallel forms is that while H. hlugii is 

 extremely rare in India, the corresponding variety of H. misippus 

 2 occurs there not infrequently '. It is also worthy of note 

 that the white-winged West- African form, Limnas alcippus Cram., 

 is accompanied by the ordinary, and not the white-winged, form of 

 H. misippus 2 •
