aD Psyche [February 
6. I am unable to account for the occurrence at the same place of 
H. maia as typical form with a strongly marked local form. 
If mara and lucina are really so closely related, we should 
expect crosses to take place in nature, especially as when 
maia males first emerge, only females of /uwcina are present, 
since the flying period of the two species overlaps only in the 
latter part of September. So far, however, no specimen has 
been found, which could be a cross between the two, that is to 
say, one which shows characters of both, for the individuals 
of both forms are always easily separated from one another. 
Henry Edwards has already mentioned in his description of 
fF. lucina (1. ¢.) as a very noteworthy fact that all the specimens 
of mata which had come under his observation were readily 
known as such in spite of their considerable variability, while 
he was always able quickly to distinguish them from /ucina. 
The species and aberrations of Hemileuca occurring in the New 
England States would therefore be the following: 
Hemileuca maia, Drury. 
Hemileuca lucina Hy. Edwards. 
ab. obsoleta Reiff. 
ab. lutea Reiff.
