A male caught in August and a female captured in June 1910,

Sir George F. Hampson in his Catalogue treats the last two forms 

 here listed as being merely varieties of M. invaria (Walker). I find it 

 difficult to agree with him. There are before me, as I write, some 

 hundreds of specimens of Walker's species, representing numerous 

 localities, and they all agree very closely; there are also some scores of 

 each of the other two forms from widely separated localities, and these 

 also agree closely and are easily distinguishable at a glance from typical 

 M. invaria and from each other. Until the test of breeding shall have 

 demonstrated the fact that these three forms are derived from one and 

 the same batch of eggs, it appears to me preferal^le to distinguish them 

 as species, instead of "lumping" them under Walker's name.
