Stenocranus croceus Van D. Ames. 
Liburnia vittatifrons Uhl. Not common except in particular 
locations. 
Scolops grossus Uhl. Common in 1896. 
Vanduzea arcuata Godg. Occurs on locust and usually very 
abundant where found, Ames and Albia. 
Telamona godingi Van D. Ames. Not common. 
Stictocephala lutea Walk. Common. Confused with inermis. 
Publilia modesta Uhl. 
Diaspis rosce. Muscatine. Very abundant and destructive 
to roses and other garden shrubs. A serious pest where it 
occurs. 
Ecematopinus pedalis Osb. An interesting parasite of sheep, 
occurring on the feet and lower part of legs, but not on wooly 
parts of the body. 
EuhcBmatopinus abnormis Osb. A very peculiar parasite of the 
common mole Scaloj^s argentatus. The femora of the hind legs 
bear disk-like processes which evidently oppose the tibiae of 
the middle legs as a clasping organ. I have described it in 
a bulletin on “The lasects Affecting Domestic Animals,” 
recently issued by the Div. Eat. U. S. Dep. Agriculture.

In plates xxii to xxv four species are shown on each plate, each one occupying one-

letters correspond for each species, notice of which will avoid any possible confusion 
in reference to figures.
