Dr. Fitch described six new genera, 85 new species, and five new 
subspecies in his Homoptera catalogue. The New York State 
Museum’s collection still contains type specimens of 60 of the 
species and subspecies. The remainder have been considered 
destroyed (Lintner 1893, McCabe and Johnson 1980). The speci- 
mens that Dr. Fitch listed in his catalogue were numbered 609-874, 
and he tagged the specimens with numbered labels printed expressly 
for that purpose (Funkhouser 1915). These numbers bear no 
relationship to the numbers in Dr. Fitch’s manuscript species notes 
or specimen registers. In the United States National Museum there 
are six specimens labelled in Dr. Fitch’s handwriting with three digit 
numbers that correspond with those in his Homoptera catalogue. 
They are two specimens of Psyllidae, Livia femoralis Fitch (838) and 
L. vernalis Fitch (836), and four specimens of Aphididae, Aphis 
betulaecolens Fitch (848), A. cerasicolens Fitch (841), A. berberidis 
Fitch (842), and A. sambucif oliae Fitch (850). Specimen 842 is also 
labelled Aphis pinicolens Fitch, but not in Fitch’s handwriting. A 
seventh specimen in the USNM — a specimen of Aphis cornifoliae 
Fitch — is labelled “846 Fitch,” “Type,” and “Female,” corre- 
sponding with the information given in Fitch’s catalogue, but these 
labels are not in Fitch’s handwriting. Two more specimens of 
Aphididae, Lachnus abietis Fitch (854) and L. alnifoliae Fitch (857),
