PHILvENUS LINEATUS Linn. • 
Cicada Uneata Linn. Faun. Suec., 241, 888, 1761. 
Ptyelus basivitta Walk. ListHomop. B. M., 718, 1851. 
Pale creamy-yellow with a light stripe along the costa inside 
of which may be a dark stripe. Smaller and narrower than 
spumarius, with the elytra nearly parallel margined, the head 
long and angular; length 4. 5-6. 5mm., width 1.5-2mm. 
Vertex, flat, nearly rig-ht-angled before, the sides rounding, length equal 
to two-thirds of the width, almost as long as the pronotum, a faint median 
Carina; tylus narrow, longer than width at base, about equal to the rest of 
the vertex; ocelli equidistant from tylus and pronotum and also from eyes 
and each other; front broad, strongly ribbed, making an acute angle 
with the vertex; rostrum short and stout scarcely reaching the middle 
coxae, shorter than the front; pronotum small, flat, broadly rounded in 
front, usually three or four longitudinal depressions on the anterior portion 
of the disc; elytra nearly parallel margined, the costal margin curved 
inward on the middle, venation simple, normal, the outer sector of corium 
forking near the middle of the posterior half of the elytra, forming a^broad 
discoid cell scarcely three times longer than wide, rounding at the fork; 
wings with the third vein from the costal vein entire. 
Color: Above, pale creamy-yellow with a short prostrate, golden pube- 
scence covering the entire surface, costal area of the elytra pale creamy- 
white becoming yellowish posteriorly, a dark stripe runs back from either 
eye crossing the pronotum below the carinate lateral margins, then on to 
the elytra where they follow the outer sector, fading out posteriorly, a dark 
spot on the suture just beyond the apex of clavus, sometimes continued as a 
dark margin around the apex of elytra. In some males the dark stripe 
spreads out inwardly and covers nearly the whole of the elytra inside the 
white margins. Front and below darker with a pale longitudinal stripe on 
either side just below the eyes. 
Genitalia: Female pygofers no longer than their basal width, narrow- 
ing apically, exceeded by the long ovipositor, more than half their length; 
male plates broad at the base curving upward at nearly right angles to the 
abdomen, their inner margins straight, attingent, outer margins parallel or 
slightly narrowing to beyond the middle, then widening and forming an 
obtuse outward angle beyond which they are cut off obliquely, each plate 
three times longer than wide. 
Habitat: (Europe). Specimens are at hand from St. Johns, 
N. B., New Hampshire, and New York, and it has been reported 
from Nova Scotia, Ontario and Maine. The reports from the 
middle and western states probably all refer to Mlineatus, as that 
species is common in those sections, while Imeatus has not been 
received from outside of the the eastern states The specimens 
from New Brunswick are smaller and inclined to be tawny 
and answer the description of Walker’s species {basivitta) from 
Hudson’s Bay so well that there seems to be no doubt but what 
ongs here.
