ON CERTAIN BRITISH HUMIPTERA-HOMOPTEItA.

 {continued from Vol. ix, p. 238.) 

 Species. — Liburnia perspicillata, Boh. 

 Delpliax perspicillata, Boli., Ofvers., ii, 164, 31 (1S51) ; Hand!., G2, 32 

 (1845) ; Stcll, Ofvers., xi, 191, 7 (1845) ; Kirschb., Cicad., 31, 

 26 (1868). 

 KeJisia perspiciUata, Fieb., Yerh. z.— b. Wien., 532, 6 (1866). 



Developed form, $ . 



Tellow. Cheeka witb a large black spot. Elytra, pale, almost 

 transparent, as long as the abdomen. 



Head yellow, somcwlmt longer than broad, rounded in front. Croivn — keels not 

 prominent ; frons somewhat brownish. Fare : cheeks with a hirge black spot. 

 AntenncB yellow, granulation black. Eyes black or purplish-brown. 



Thorax : proiiotum and scutelliim yellow, keels not prominent. Elytra as long as 

 the abdomen, pale, almost transparent ; outer edge of the anterior marginal 

 nerve in certain lights very narrowly blackish ; nerves distinct, not granulated. 

 Sternum yellow, with a round black spot just above the base of the 1st pair of 

 legs. Legs yellow. Tarsi — extreme apex of all the pairs and claws black. 



Abdomen above blackish, more or less broadly fuscous-yellow down the middle ; 

 beneath yellow ; ovipositor black. Length, 1 line. 



Smaller than L. guttula, next to which species it will stand in our 



lists. The entirely yellow pronotum and scutellum, and absence of 



the black streak in the elytra, will be found sufficient to separate it 



from the last named. 



. I have only seen a single $ example taken by Mr. Hardy on the 



Cheviots in October, and I have compared it with an original ? type 



of Boheman's, given to me some years ago by my friend, Dr. Stal, and 



with which it agrees in every respect.
