lOG [October, 



? . Entirely ochreous-yellow. Elytra pale, transparent, reaching to a little beyond 

 the middle of the abdomen, posterior margin somewhat broadly rounded, nerves 

 distinctly punctured. Legs yellow ; tarsi as in the $ . 



Length, <? i, ? 1 line. 



The ^ in appearance A^ery much resembles the undeveloped form 

 of L. 2^elhicida, but the elytra are longer than in that s^^ecies ; and 

 besides the different colour of the head, and generally the pronotum 

 and scutellum, the different form of the opening of the last genital 

 segment when viewed from behind, as well as the styloid processes, 

 at once serve to separate them. 



I have named the species after M. Lethierry, who, with Dr. 

 Puton, has acquired the whole of the late Dr. Fieber's valuable 

 drawings of Homoptera, and from whom I have already received 

 valuable assistance. 



Both sexes were taken by the E.ev. T. A. Marshall in Corsica. 



LiBUBNIA GUAEAMANENSIS, sp. n. 



Undeveloped form. 



(^ . Testaceous, with a faiut clear brownish tinge. Sciiiellum— 

 disc with a distinct puncture near the apex of the side keels. 



Head longer than broad, testaceous ; crown — keels not prominent. Face concolorous, 

 keels somewhat prominent and acute. AntenncB pale brownish-testaceous. Eyes 

 large, pale brown. 



Thorax : pronotum testaceous, middle keel somewhat faint, disc with a sliort, narrow, 

 transverse fovea on each side of the middle, almost in a line with the posterior 

 margin of the eyes. Scutellum clear pale brown, keels distinct ; disc a little 

 below the apex of the side keels with a distinct puncture. Elytra testaceous, 

 reaching to beyond the middle of the abdomen, posterior margin flattish convex, 

 nerves fine, unpunctured. Eeys yellow. 



Abdomen clear pale brown or brownish-yellow ; last genital segment and styloid 

 processes concoloi'ovis ; opening of the former viewed from behind somewhat 

 resembling the section of a carafe or water bottle with a short, wide neck. 



Length, J line. 



Unlike any sj)ecies which I have hitherto seen. The head some- 

 what resembles X. spinosa, Mink, but beyond this there is nothing 

 more in common between them. 



I took a single (J specimen near Linares, Andalusia, by sweeping, 

 and which I am sorry to say is sadly mutilated through having es- 

 caped notice, and remained so long in a cyanide bottle. It wants an 

 elytron and nearly all the legs, and the somewhat defective descrip- 

 tion must be attributed to these imperfections.
