SPITTLE-INSECTS OR FROG-HOPPERS. ULF 
Scolops sulcipes Say. (The Candle-head). 
It lives on grass and various other plants growing in low 
ground, and is also frequently seen along the edges of wood; 
in the prairies it occurs in large numbers on grass growing near 
wet places. The illustration, Fig. 110, shows its peculiar shape. 
It is oval, dull straw colored, with a long, slender, up-curved, 
candle-shaped projection starting from the front of the head. 
The eyes are brown; the veins of the wing-covers are margined 
and spotted with the same color. 
Another quite different form is shown in Fig. 111. It is a 
gayly marked species, either lemon-yellow or cream-colored, with 
a broad stripe on the side of the face and wavy red forked lines 
on the wing-covers. Looking at the head from the side it looks 
like a plough-share, with the little brown eyes standing out like 
beads. 
This species, (Otiocerus coqueberti Kby.), occurs upon the 
leaves of the grape-vine, oaks and hickory, and is found during 
July, August, and September. 
Fic. 111.—Otiocerus coqueberti Kby. After Uhler. 
Many other peculiar and equally interesting forms occur in 
our state, but as none of them cause any particular injury to our 
crops, those mentioned above will be sufficient to give a general 
idea of the family. Fig. 112 (Plate III) is a very beautiful in- 
sect, hence the name Liburnia ornata Stal. It is found sometimes 
in numbers on the foliage of the sugar beet. 
FAMILY CERCOPIDAE. 
(Spittle-insects or Frog-hoppers). 
“Tn the great family Cercopidz we observe forms quite unlike 
any that have been previously noticed, and some which mark an 
important advance in the direction of the Heteroptera by the
