MEMBRA CIDAE. 
always fuscous in colour, and shows a distinct carina; legs ochreous or indistinctly 
brown ; the discoidal areas of the tegmina are usually nearly equal in size, but the 
extreme area is the smaller. 
The puncturation of the pronotum as in my figure is drawn much coarser than is 
represented in Canon Fowler’s figure, in fact it appears more as depressed blotches 
between the cariuse. This species is described in the Biologia, p. 132, as very 
like small specimens of Lucilla, which genus, I conclude, is there considered 
synonymous with Metheisa. It is there noted as having the dorsum slightly 
protuberant behind, and not in front of the shoulders. 
Viewed from the back the insect recalls the allied genus Polyglypta.

METHEISA (LUCILLA) CUCULLATA, n.s. 
(Plate XXXIX. fig. 8,) 
The conspicuous white spot on the pronotum, and the general contour of my 
figured example, seem to justify its position as a species, and I name it from its 
hooded appearance. 
METHEISA SINUATA, n.s. 
(Plate XL. figs. 1, la, lb.) 
Robust, obtuse, compressed; dorsal ridge of the pronotums viewed in profile 
slightly convex, then suddenly perpendicular to the face; lower and lateral part 
strongly sinuous; upper ridge of a bright ochreous yellow, with fine spots on the 
pronotum between the carinse; several black streaks and dots run in rows from the 
cephalic part towards the metopodium, and there are fine black lines at the posterior 
part of the pronotum ; tegmina dark brown and covered ; legs strong and obscurely 
red ; tarsi long ; eyes prominent; frons flat. 
Size, 8x5 mm.

OXYGONIA ACCUMINATA, n.g.
