British Homoptera-Cicadina. 113 



siibopaqiie, a stripe along the costa, a wide band across the middle, 

 and another across the base of the membrane, fuscous ; apical 

 half of the clavus mottled with fuscous ; nerves concolorous. 

 Length (male), 4 mm. 



Darenth, July. Examples in which the markings of 

 the elytra are wanting might be mistaken for P. impurus, 

 hut on comparison of the two the narrower and more 

 pointed form of distinctus is very apparent. 



9. Pediopsis ulmi, Scott. 



Pediopsis nlmi, Scott, Ent. Mo. Mag., x., 129, 2. 



Fore parts brownish yellow. Scutellum with a brown triangle 

 on each side at the base. Elytra and legs yellow-brown, the 

 former subopaque with the costa narrowly dark brown and the 

 nerves concolorous. Hind tibias with a black spot on the outer 

 side at the base. Abdomen above (male) black, hind margins of 

 the segments narrowly pale ; female brownish yellow. Length, 

 4 — 5 mm. 



On elm. Lee and Norwich. 



10. Pediopsis cereus, Germ. 



Jassus cereus, Germ., Faun. Ins. Eur., 17, 14. 



Pediopsis cerea, Fieb., Eur. Bythosc, 458, 2; Scott, 

 Ent. Mo. Mag., x., 130, 3. 



Face greyish yellow. Upper side reddish yellow-brown. Scu- 

 tellum sometimes with a red-brown triangle on each side at the 

 base. Elytra subopaque, just behind the middle a broad red-brown 

 band, which seldom reaches the inner margin and never the costa, 

 nerves concolorous. Legs concolorous, hind tibisE as in the last. 

 Abdomen above (male) black, hind margins of the segments 

 narrowly pale ; (female) brownish yellow. Length, 4 — 5 mm. 



Common on sallows. Very frequently the dark brown 

 baud on the elytra is only indicated on the inner 

 margin, though it is rarely entirely wanting, and in 

 this state the species is best distinguished from ulmi 

 by its habitat and the want of the brown line next the 

 costa.
