^ PHIL^NUS LINEATUS Linn. 

 ^ Cicada lineata Linn. Faun. Suec, 241, 888, 1761. 

 oPtyelus banvitta Walk. List Homop. 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 right-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 

 coxa?, 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 ovipositer, 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 aMretertcPbilineatu.s, as that 

 species is common in those sections, while'^lhieafu.s 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 (bai^ivitta) from 

 Hudson's Bay so well that there seems to be no doubt but what 

 ongs here.
