Dr. Asa Fitch (1809-1879) proposed 165 new species and 
subspecies names in the Homoptera. They are taxonomically 
distributed as follows: Cicadidae (2), Membracidae (21), Cicadelli- 
dae (34), Cercopidae (9), Delphacidae (2), Derbidae (7), Cixiidae 
(2), Achilidae (2), Issidae (2), Psyllidae (9), Aleyrodidae (1), 
Aphididae (52), Adelgidae (2), Phylloxeridae (4), Diaspididae (5), 
and Coccidae (11). He proposed the names in print from 1851 to 
1872, mainly in his Homoptera catalogue (1851) and the Trans- 
actions of the New York State Agricultural Society. 
Dr. Fitch never designated types for his new species and 
subspecies. However, he did label nearly all of his specimens with 
individual numbers. He recorded these numbers consecutively in 
four individual registers, along with collecting dates, localities, and 
other pertinent information. Label numbers in black ink written on 
white paper are recorded in one register of specimens from New 
York State. Label numbers in black ink crossed with one or two red 
lines and written on white paper are recorded in a second register of 
specimens from New York State. One red line indicates a number 
less than 10,000, and two red lines indicate a number to which 
10,000 should be added. Label numbers in red ink written on white 
paper are recorded in a third register that lists specimens from 
elsewhere in North America. These three registers are in the 
possession of the New York State Museum. The fourth register, 
owned by the Museum of Science, successor to the Boston Society 
of Natural History, lists specimens from elsewhere in the world. The 
corresponding labels are written in black ink on colored papers. Dr. 
Fitch also kept individual sheets of notes on every species of which
