70 (August, 
Species 17.—LiBuRNIA MELANOPACHYS. 
Delphax melanopachys, Fieb. (M.S.). 
Undeveloped form, 3. 
Head: crown clear brown, the three fovee deep and distinct, keels acute and 
prominent. Face (except the forehead), clypeus, and cheeks black. Antenne 
clear brown, 2nd joint about 1} time longer than the Ist. 
Thoraz: pronotum clear brown, keels acute and prominent, posterior angles broadly 
black ; scutellum clear brown, keels distinct, sometimes the middle keel and a 
narrow margin on either side, especially towards the apex, blackish ; sides, 
beyond the side keels, black. Elytra about two-thirds the length of the abdo- 
men, lacquer-yellow, shining, somewhat transparent, nerves prominent, un- 
punctured ; posterior margin rounded. Sternum black. Legs yellow; tarst, 
1st and 2nd pairs, brown, 3rd, yellow. 
Abdomen above, pitchy-brown ; underneath black; genital segment black. 
Length, g, 1 line. 
Altogether a larger species than Z. venosa, to which it bears a 
great resemblance, but it is at once to be distinguished from it by the 
characters on the pronotum and scutellum, as given above. 
The peculiar lacquer-yellow colour of the elytra is only met with, 
at least amongst British species, in ZL. venosa, and the present insect, 
but in the former it is not nearly so clear as in the latter. 
The discovery of this interesting species is due to Mr. T. J. Bold, 
who took a single g specimen in Gosforth Woods in October.
