MEMBRA ClDJE. 
STICTOCEPHALA INERMIS. 
(Plate XXXVI. figs. 5, 5a, 5b.) 
Pronotum convex and without any suprahumerals ; metopidium high and sub¬ 
acuminate ; finely punctured, and with a feeble central carina; abdomen large, ringed 
with pale orange red; eyes grey; tegmina and wings transparent, with orange 
neuration much on the type of Ceresa, if not identical with it; legs pale brown, the 
two first pair hirsute. 
Stal separates Stictocephala from Ceresa chiefly from the unarmed character of 
the pronotum, but Fowler says the genetalia differ, and this might be a sufficient 
reason for generic separation, though it might merely point to specific variation. 
General colour dull orange yellow. 
Size, 6x4 mm. 
Habitat .—Trenton Falls, North America. 
STICTOCEPHALA SEMI-BRUNNEA, n.s. 
(Plate XXXVI. fig. 6.) 
Aspect very similar to the last described species, but the fore part of the pronotum 
is of a rich brown, as is also all the underside; tegmina fusco-hyaline, with a broad 
crinkled limbus ; legs ochreous and concolorous with the hinder part of the pronotum. 
From the collection of T. V. Wollaston, Esq. 
Habitat .—New York. 
STICTOCEPHALA LUTEA, St&l, var. 
This insect is very like a small example of S. mb'mis, but notwithstanding its 
small size, the locality, Trenton Falls, New York, might be some argument for its 
separate identity. Still in want of further particulars and proof, I hesitate to consider 
it distinct, though it is labelled lute a in the National Collection at South Kensington. 
Taken by Mr. E. Doubleday. 
Size, 4x3 mm. 
Genus : CENTROGONIA, Stal. 
The species of this genus are exceedingly like those of Ceresa or Nassunia. It 
includes Ceresa citiata, of Fairm., P. nasala, Stal, C. unguicitlaris, Stal, and C. elegans 
of Fowler. Tab. VIE, figs. 16, 16a, p. 107. 
CENTROGONIA MACULATA, n.s. 
(Plate XXXVI. figs. 7, 7a.) 
Pronotum smooth, unarmed, and without suprahumerals ; surface variegated with 
grey blotches and a conspicuous red stain on the dorsum near the apex ; tegmina
