THE YELLOW-HEADED LEAFHOPPEK.

Tettigonia reticulata in 1854 from specimens derived from Cuba and 
without any statement concerning its importance. Later, in 1880, 
it was redescribed by Prof. C. V. Riley and renamed Diedrocephala 
flaviceps, and in connection with the description appears the note, 
''Numerous specimens injuring wheat and oats in Texas." In Insect 
Life there is a record of its destructive abundance in South Carolina, 
and the records of the Bureau of Entomology include a number of 
instances of its occurrence in wheat and other cropSc 
DISTRIBUTION. 
In Van Duzee's catalogue the distribution of the species is given 
as from Carolina to Texas. Ball gives a further statement of dis-

tribution covering South Carolina, Georgia, Florida, Alabama, Mis- 
sissippi, Louisiana, South Carolina, and Mexico, which, with the 
original description from Cuba, gives it a considerable range. Records 
in the Bureau of Entomology add Charlottesville, Va., as a more 
northern point, and during the past season it has been found in large 
numbers at Raleigh, N. C, Clemson College, S. C, and Decatur, 
Ga. There is one record of its occurrence in Lincoln, Nebr., which 
is the most northerly point from which we have found any indica- 
tion of its presence, and so remote from other recorded localities 
that it may be based on an exceptional occurrence. If common 
there, it should also be found at intermediate points between tins 
and Texas, but careful collecting has failed to discover it in Kansas. 
There is also a record for Fulton, Ky. I took it in Mississippi and 
also in Tucson, Ariz., in 1910. Prof. Ball has a record for Salina, 
Cal., and I took a similar form at Yuma, Ariz., in wild grass, but
