apex, on the inner margin forming a longitudinal row of short streaks, the 
posterior angle clear black ; marginal channel pale livid tawny ; membrane- 
suture very narrow, yellow. Membrane filled with short, curved and twisted 
yellowish marks, inner margin broadly black. Sternum black ; scajpula, 
pleura;, and parofpleurce pale yellow. Legs brown-black ; thighs tawny at the

Allied to O. Fabricii, Pieb. 
Two specimens, received by Mr. Brewer, were captured in Shetland, 
in 1866, by Mr. E. Smith. 
CoEixA Whitei, n. sp. 
Tawny-black, with obscure yellowish markings, shining. Pro- 
notum, clavus, and corium finely rastrate. Pronotum with 7 — 8 scarcely 
perceptible yellowish lines, the middle ones interrupted ; clavus and 
corium with indistinct, fine, yellowish lines, on the former straight, 
much shortened inwardly, on the latter short and sinuous ; marginal 
channel pale. Sternum entirely pale ochreous. 
Head — Crown brown, posteriorly raised into a sub-acute point, on each side of the 
elevation a row of 4 or 5 punctures ; face yellowish. 
Thorax — Pronotum in front with a short keel ; disc with 7 — 8 obscure yellowish 
lines, straight, except 2 or 3 in the middle, which are interrupted by the 
junction of the narrow, incised, intervening black lines. Elytra — clanms 
with fine, distant, oblique, straight yellowish lines, all visible on the outer 
margin, but so much abbreviated inwardly that the disc appears black. 
Corium with short, sinuous, interrupted, transverse yellowish lines, some- 
times connected by longitudinal streaks ; inner posterior angle wholly black j 
marginal channel pale ; membrane-suture distinct, yellowish. Membrane 
with very fine, short, hieroglyphic markings. Sternum, scapulce, pleurce, and 
parapleurw pale ochreous. Legs tawny-brown ; thighs paler at the base ;

Intermediate between C. Fabricii and G. moesta. A single ? taken 
by Dr. F. Buchanan White, at Eannoch, in 1867. 
The next two species belong to the section of the genus in which 
the pronotum has a long middle keel — not hitherto represented in our 
collections by British examples.
