elytra arc of a more or less sanguine red, and have an interrupted, transverse, dorsal, 

 black band, consisting of four large, oblong spots, those at the mai'gin and sutui'o 

 being largest ; before the apex is another band, irregularly arched, and strongly in- 

 dented ; the sutiu'e, and the extreme margin, as far as the first dorsal band, are black. 



Length, 3| lin. ; vridth of elytra, 2 liii.

APSIDA (Dej.), Lacordaire, Gen. d. Col., v, p. 309, oidte. 



Mentum trapezoidal, the disc more or less strongly convex ; last joint of labial palpi 

 ovoid, more or less attenuate, and narrowly truncated, at apex, and of the maxillary 

 palpi triangular, with the apical angle more or less strongly produced ; outer five 

 joints of antennae expanded ; epistoma broadly and slightly sinuously truncated in 

 front nearly on a level with the insertion of the antennae ; the sutural line distinct 

 throughout ; labrum broad, narrowly emarginate in front, the angles rounded, the 

 membranous attachment broadly exposed ; eyes rather small, narrow, moderately 

 prominent, not obliquely prolonged on the front, distant both above and beneath, 

 emarginate in front ; antennary orbits wide, rounded at the sides ; prothorax trans- 

 verse, gradually — and but slightly curvedly — narrowed from base to apex ; apex 

 more or less deeply arcuate-emarginate ; median basal lobe rather broad and sub- 

 truncate behind ; the lateral margins more or less (but never strongly) thickened 

 and slightly channelled vritliin ; scutellum large, curvdinearly triangular ; elytra 

 strongly convex — almost gibbous — a little before the middle {chrysomelina) , or simply 

 and regularly convex {Belti), more or less gradually declivous behind ; epipleural 

 fold rather broad, more or less abruptly terminating at, or near to, the fourth ventral 

 suture ; prosternum very short, more or less compressed and convex in front, the 

 process broad, robust, sometimes a little declivous behind, end broadly rounded ; 

 mesosternum short, vertical in front, and broadly, and more or less deeply and 

 angularly emarginate, the upper face plane, smooth, or with an oblique impression 

 at each side ; metasternum transversely concave behind (the concavity corresjionding 

 with the convexity on the back), or slightly convex ; intercoxal process broad, more 

 or less rapidly narrowed to the apex ; legs moderate, femora compressed, moderately 

 claviform ; tibiae slightly bowed, gradually thickened outwardly ; 1st joint of hind 

 tarsi moderately elongate ; body shortly oval, elongate oval, or ovate. 



This genus — very briefly characterized by Lacordaire — may at 

 once be distinguished from Semicera by its 5- jointed antennal club ; 

 its smaller, narrower eyes, not obliquely j)roduced on the front or 

 approximate above ; its wider antennary orbits ; its prosternum less 

 strongly compressed before the coxse, &c. 



I am not at all certain that the species I have described as chry- 

 somcliua is the same as that mentioned by Lacordaire. 



Apsida chetsomelina, sp. n. 



Short-oval, dark bronzed-green, shining ; head minutely and sparsely punctu- 

 late ; prothorax impunetate, gradually narrowed from base, a little mcurved at the 

 apex, which is rather strongly arcuate-emarginate ; scutellum shining black, im- 

 punetate ; elytra strongly convex — almost gibbous — before the middle, each with
