Coeixa Boldi, n. sp. 

 $ . Black-brown with pale yellow markings. Pronotum with 7 — 8 

 very fine interrupted black lines. Clavus with long, zig-zag, longitudinal 

 Hues in the middle, and short transverse lines on the sides. Corium 

 with short, twisted, transverse lines. Posterior tarsi ; the 1st joint with 

 a large, apical, black spot, semi-oval on its upper end. 



Head brownish-yellow, fuscous at the base, with a short, punctate, longitudinal 

 stria on each side of the slightly raised middle. 



Thorax : pronotum, clavus and corium finely rastrate. Pronotum posteriorly 

 rounded, anteriorly without a keel, transversely with 7 — 8 very fine, slightly 

 impressed black lines, the intermediate yellow lines rather wider. Elytra : 

 clavus with long, zig-zag, sharply angulated, longitudinal, yellow lines on the 

 middle, broad at the base, the margins each with a series of short hieroglyphic 

 marks, sometimes connected; on the posterior 4th these marks form irregular 

 transverse lines : corium with short, twisted, angulated, somewhat oblique 

 transverse lines, interrupted on the posterior inner angle by a longitudinal 

 black streak, the angle itself, at the end of the clavus, with a black spot ; 

 marginal channel pale yellowish ; membrane-suture narrow, dusky yellowish : 

 membrane filled with hieroglyphic yellowish markings, intei'rupted near, and 

 parallel to, the inner margin by a pale streak, exterior margin black, posterior 

 margin fuscous. Sternum pale yellow. Legs pale yellow : 1st pair, pate, ?, 

 cultrate, narrow, acute : 2nd pair, tarsi with a brown spot at the apex : 3rd 

 pair, 1st joint with a large, apical, black spot reaching quite across the joint, 

 the upper end of the spot semi-oval; 2nd joint with a delicate black margin; 

 cilia black. 



Abdomen above, black ; sides and connewivum pale yellow ; the last segment, within 

 the posterior margin, with a brown line ; under-side pale yellow. 



Length 3 lines. 



This species is at once distinguished by the longitudinal direction 

 of the peculiar markings on the clavus. By the spot on the posterior 

 tarsi it is related to O. prceusta, but the form of the spot differs, being 

 sub-oval, instead of quadrate. 



Described from a single ? , taken by Mr. T. J. Bold in August, at 

 Grosforth, " in a lake into which a burn runs." 



Coeixa sodalis, n. sp. 



Brown-black, with fine pale yellow markings. Pronotum with 

 8 — 9 very fine black lines. Clavus ; the lines on the basal half straight 

 or furcate ; corium with irregular, interrupted, twisted lines. Palm,$ , 

 anteriorly, on the upper-side, roundly dilated to the broad apex, out- 

 wardly, like the tibia?, black : tarsi ; 3rd pair, the 1st joint with a small 

 triangular, apical, black spot.
