that two similar insects occurring in the same woods, often at the 
same time, should never copulate. The individuals surely 
recognize a difference that many entomologists fail to see, that 
nature has separated them widely and distinctly, and that they 
have nothing in common, although they bear a superficial resem- 
blance to each other. Of course we are all aware that insects do 
copulate at times in a very erratic manner; we hear of Diurni 
copulating with Pyrales, and Bombyces with Noctue, but such 
cases are so exceptional that they may be set aside. The 
copulation of allied species is more common, but really, con- 
sidering the number of insects, and the close alliance undoubtedly 
existing between many of them, the number is,still very small, 
and nature rarely seems to deviate from her general paths. I 
have never myself seen a case of copulation between different 
recognized species, except with Agrotis nigricans and A. tritici, 
and then only in about ten instances out of some hundreds of 
insects thus noticed, and I would not like to stake much on the 
identity of all these Agrotis nigricans. There seems to be little 
doubt that the Scotch Tephrosia from Perth is identical with our 
southern crepuscularia. A series I have received from Messrs. 
Lawson and Macgregor are exceedingly fine, and the latter gen- 
tleman has kindly sent me a pair taken in copulation on April 
8th, the male a finely-marked typical specimen, the female a pale, 
well-marked specimen, coinciding exactly in size and colour with 
the July brood. It seems to me remarkable and worthy of notice 
that so far north, where crepuscularia is only single-brooded, a 
small percentage of the progeny apparently assume the size and 
superficial resemblance of our southern July brood. I think Mr. 
South must go further than he does to find the differences we 
cannot agree upon.—J. Turr; Blackheath.
