HEMIPTERA. VAN DUZEE. 49 
271. Stictocephala festina Say. Abundant everywhere on alfalfa 
throughout the year; the var. rufivitta occasional with the 
typical form. 
272. Stictocephala nigricans n. sp. 
Form of collina but smaller with the clypeus more produced; 
greenish fuscous or almost black, usually distinctly dotted with 
pale. Length 514 to 6 mm. 
Head unusually flat and regularly rounded before, the clypeus 
scarcely advanced beyond the line of the cheeks; surface not per- 
ceptably rugose, with a distinct incised median basal line. Prono- 
tum much depressed as in gilletti, the acute decurved apex almost 
reaching the tip of the abdomen; metopidium moderately convex, 
its sides narrowing from the base, curving back and meeting be- 
hind the middle. Elytral nervures strong, subinfuscated. Last 
ventral segment of the female deeply cleft almost to its base, the 
sides of the sinus arcuated nearly to the lateral angles. Color 
normally greenish fuscous, mottled or dotted with pale. Metopid- 
ium paler and at times without the mottling. Face usually pale 
with the tylus and apex of the cheeks blackish and there may be 
three darker basal clouds. Body beneath black; rostrum, legs 
and apex of the genital segment in both sexes pale. 
Described from numerous specimens swept from alfalfa on 
which it is almost as abundant throughout the year as is festina. 
This species seems to be very near Fowler’s fusca but his figure 
shows an insect with a higher pronotum with the metopidium 
conspicuously widened upward for some distance from the base; 
he also describes the abdomen as pale while it is black in even the 
palest specimens I have of nigricans. 
273. Parantonae hispida n. sp. 
Pale testaceous or yellowish, obscurely marked with ferrugin- 
ous and dotted with black; pronotum semivitreus and with the 
head armed with long erect bristles. Length 6 mm. 
Head uneven, polished; anterior edge slightly recurved, trun- 
cate on either side of the clypeus and rounded toward the eye; 
clypeus large and tumid at base. Pronotum moderately elevated; 
obscurely punctate or subareolate, divided into three lobes by trans- 
verse impressions, the anterior less profound; anterior lobe tumid 
either side above the obtuse humeral angles; no supra-humerals; 
intermediate lobe smaller, ovate, compressed below where there is 
a bulbous expansion next the margin; posterior lobe less inflated, 
subglobose, broader than high, in the male about attaining the tip 
of the abdomen, armed behind with an abrupt slender spine which 
reaches the apex of the inner areole of the elytra. Head and pro- 
notum armed with long stiff black bristles interspersed with slight- 
ly shorter pale ones, the black ones about as long as the distance 
between the ocelli and eyes. Elytra entirely hyaline, with strong 
nervures. Last ventral segment of the female deeply, broadly 
emarginate almost to its base. 
Color pale flavo-testaceous, the pronotum semivitreus, more
