Both Cresson (Synops. Fam. Gen. Hymen., 1887, p. 255) and 
Dalla Torre (Catalog. Hymen., 7, 1893, p. 247) assumed that 
Fitch’s F. carye was merely a synonym of Camponotus pennsyl- 
vanicus, but, as we have seen, Fitch was well acquainted with this 
ant under the old name F. herculeana and we could hardly suppose 
that so competent an entomologist would redescribe it under a 
new name. And although some of the distinctive characters are 
omitted in the description of carya, it is, nevertheless, sufficiently 
explicit, even if the ethological notes and the types did not make 
the identification certain. . 
In conclusion the twenty described subspecies and varieties that 
must now be referred to the American cary@, as the specific type, 
instead of to the European fallax, together with their known 
distribution, may be listed as follows: 
North American Forms. 
C. carye Fitch.—United States and British America. 
var. minutus Emery.—United States and British America. 
var. pardus Wheeler.—New York and New Jersey. 
var. tanquaryt Wheeler.—Illinois. 
var. decipiens Emery.—Indiana to Utah. 
subsp. rasilis Wheeler.—Gulf States to Arizona. 
var. pavidus Wheeler.—Gulf States. 
subsp. subbarbatus Emery.—New Jersey to California. 
var. paucipilis Emery.— Maryland. 
subsp. discolor Buckley.—Texas to Illinois. 
var. clarithorax Emery.—Pennsylvania to California. 
var. enemidatus Emery.—Maryland.
