above and within the ocelli. There is a slender impressed median line, 
black or dark brown; and a depressed spot upon each side appears 
midway between this and the eye. 
Front, bluish black, with a few yellow median points and a row 
of transverse yellow lines interrupted across the middle. Cheeks 
black above, yellow behind; basal joint of the antennae blackish be¬ 
neath ; clypeus black in the middle and at the margins, yellow at 
the sides. Lores yellow, bordered with black. Pronotum longer 
than the head, but slightly narrower, strongly arcuate in front, base 
nearly straight, yellow anteriorly (where it is also mottled with 
white), shading to dark green posteriorly, owing to the black tint 
in the mesonotum showing through the transparent pronotal 
shield. A few faint dusky blotches just behind the eyes. 
Scutellum yellow somewhat mottled with white except two deeper 
yellow blotches just within the lateral angles. A very slender black 
impressed line. * Hemelytra yellowish hyaline, veins yellowish green; 
the costal margin broadly thickened, punctillate. 
Tergum black, posterior margins of the segments yellow. Thorax 
bluish black beneath, except the outer margins of the lateral plates 
of the mesothorax, which are yellow. Abdominal segments bine- 
black, bordered with yellow posteriorly, the two or three last seg¬ 
ments largely yellow-black, or dusky only in front. The hypopygium 
nearly all yellow, connexivum chiefly yellow irregularly mottled 
with blue-black. Valvules of the female yellow beneath and behind, 
black above and in front, spinose with long yellow bristles. 
Coxae all blue-black; anterior and middle femora with about two 
rings of black, tibiae irregularly and variably specked or ringed with 
black, legs otherwise pale, except the points of attachment of the 
larger spines, which are black. 
Total length .14 inch; length of head .001 inch; of thorax .013 
inch; of scutellum .018 inch; width of head .088 inch; width of 
scutellum .025. 
This species was collected by Mr. Garman at Mount Carmel on 
the 2Sth*of May, 1884, where it was abundant in growing oats; at 
DuQuoin on the 7th June, where he found it common in young wheat 
and .again on the 5th July, when it was obtained by sweeping in 
wheat stubble. At Anna, July 14, it was very common on young corn, 
and occasionally occurred upon musk melons, August 2. 
Cicadula quadrilineatus, n. s.* 
(Plate V. Fig. 4.) 
Similar in general appearance to Cicadula nigrifrons , but differing 
in wing veins and color markings. Head with two round black 
spots upon either side of the middle of the base, about equidistant 
from the median impressed line and from the eyes. In front o 
these a transverse black line extending from eye to eye but inter- 
^Differs from the preceding and from typical European species.of Cicadula by soDie 
structural characters; but the above generic assignment expresses its true relations-
