Walsh (Proe. Bost. Soc. Nat. Hist. ix. p. 315), in a paper reprinted from 
the ^ Prairie Farmer ’ of Sept. 6, 1862, describes twelve new species of the 
gToup representing the old genus Typidocyha (Germ.), which he proposes to 
divide into genera as in the following table : — 
I. Elytra bordered by a vein on the inner terminal margin. 
Typhlocyha, 
II. Elytra not bordered. 
A. Outer apical cell of elytra triangular. 
1. Terminal cells of wings bordered Empoasca (g. n.). 
2. Terminal cells of wings not bordered Empoa (Fitch). 
B. Outer apical cell of elytra quadrangidar. 
1. Terminal cells of wings bordered Chlormeiira (g. n.). 
2. Terminal cells of wings not bordered Eryihroncura (Fitch). 
The elytra and wings of Typhlocyha (without discoid al cell), Empoasca, and 
Erytkroneura are represented in outline on p. 314. figs. 4-6. Fig. 7 (/. c.) 
shows the ovipositor of Erythroneura. 
Ifrauenfeld (Verb, zool.-bot. Ges-, in Wien, xv. pp. 900-902) calls attention 
to a singular example of parasitism observed in a species of Typhlocyha, in 
which the parasite attaches itself to the first abdominal segment, from which 
it hangs like a small free sac. 
W alsh has noticed the habits of Proconia undata (Fab.) and Erythroneura 
tricincta (Fitch). See Proc. Bost. Soc. Nat. Hist. ix. p. 313.
