Cyphogastra quadrivittata, n. sp. 

 PI. ix., fig. 4. 

 Elongate-navicular. Upper-surface green, somewhat 

 cyaneous on the raised parts, with lighter-coloured impres- 

 sions, more or less filled with yellow flocculence ; underside 

 coppery on raised central part, green more or less obscured 

 by yellow flocculence elsewhere; legs green (antennae and 

 tarsi wanting). 



Head triangularly excised, channelled at base, with a 

 deep central fovea between the eyes, these bordered within 

 by rugose-pustulose ridge; basal part sparsely punctate near 

 middle, rugose-punctate behind eyes. Prothorax 8 x 11 mm., 

 depressed, strongly bisinuate at apex and base, all angles 

 produced and acute, base with widely-rounded central lobe, 

 widest at base, sides sinuate near both angles ; disc with wide 

 deep medial sulcus, a wide irregular flocculent impression, 

 trilobed externally, occupying the greater part of sides, the 

 raised part near centre sparsely punctate, at sides rugose- 

 punctate. Scutellum rounded and depressed in front, bilobed 

 and convex behind, with four punctures on anterior half. 

 Elytra slightly wider than prothorax at base, angularly 

 widening at shoulders and tapering to an acuminate apex 

 from the middle, each apex subrectangular at suture, with 

 about four strong serrations on posterior margins, each elytron 

 with two wide impressed vittae, golden-green with yellow 

 flocculence (where not abraded), the first extending from base 

 to near apex, near and more or less parallel to the suture, 

 the second near the margin starting behind the shoulder and 

 extending to the apex, a large floccose impression at base near 

 the middle of each elytron, a narrow lateral sulcus exterior 

 to the seccud vitta starting from the posthumeral sinuation, 

 and gradually widening and obsolescent towards apex, the 

 suture convex on anterior half, narrowing and carinate 

 posteriorly, with fine sparse punctures, the raised surface 

 between the vittae having larger and more regular punctures, 

 these gradually becoming obsolete towards apex. Presternum , 

 mesostemum, and metasternum widely sulcate ; first abdo- 

 minal segment with the usual convex plate at centre, rounded 

 behind, acuminate in front, the smooth middle parts of under- 

 side finely and sparsely punctate, the greater part of the 

 under-surface covered with orange-yellow flocculence. Dim., 

 40 x 12 mm.
