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. Fro- 

 notum, clavus, and corium finely rastrate. Fronotum 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 — clavus 

 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 ; 

 marginal channel pale ; membrane-suture distinct, yellowish. Membrane 

 with very fine, short, hieroglyphic markings. Sternum, scapula;, pleurae, and

Intermediate between C. Falricii and C. moesta. A single $ taken 

 by Dr. F. Buchanan White, at Rannoch, 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.
