of A. nais Drury, and A. saundersii Grote as synonymous with 
A. parthenice Kirby; A. anna Grote being merely a variety of the 
same species. Mr. Hulst is not singular in this respect. Ul 
own rearing experience is similar and we anticipate some pretty 
extensive coalitions in Mr. Stretch’s forthcoming monograph. 
AFFINITIES OF PaLmocampa.—In discussing the genealogy of 
the Myriopoda in a paper just issued from the Proceedings of the 
American Philosophical Society (Vol. xxi, p. 208) Dr. £ ckard 
concludes that Paleocampa—a caterpillar-like form described by 
Meek and Worthen, from the carboniferous of Illinois—s not & 
Myriopod as Scudder maintained, but that it may be regal 2 
the hairy larva of some carboniferous neuropterous insect all 
to the Panorpide. He would therefore exclude it from aly 
genealogical considerations in reference to the Myriopods.
