sides; scutellum small, triangular; elytra much broader than the pro- 
thorax, bright brassy yellow, or brassy with a golden tinge, lineate- 
punctate, the intervals between the lines with very minute scattered 
points, the intervals between the punctures brassy brown; body beneath 
and legs glossy, with a greenish tinge. Length 6 lines. 
Exrxora [Cnodalinee ]. 
Caput breve, usque ad medium oculorum insertum ; clypeus angustatus, 
apice truncatus. Labrum productum. Oculi magni. Mentum trapezoi- 
dale, medio carinatum, apice emarginatum. Labiwmsubcordatum. Palpi 
labiales approximati, in medio labii inserti, art. ult. amplo. Antenne 
apicem versus paulo incrassatz, articulis obconicis, ultimo ovato. Pro- 
thorax transversus, lateribus rotundatus, apice emarginatus, basi sublo- 
batus. Elytra prothoraci arcte applicata, oblonga, convexa; epipleure 
integra. Pedes mediocres; tibie graciles; tarsi lineares, articulo ultimo 
mediocri. Prosternum postice productum, in incisura mesosterni re- 
ceptum. Processus interfemoralis triangularis. Corpus oblongo-ovatum. 
Allied to Damatris, Lap., but differentiated by its small claw- 
joints, and the epipleurz of the elytra entire and gradually narrow- 
ing to the apex. The last joint of the maxillary palpus is nearly 
three times the size of the outer maxillary lobe. The type resembles 
an oblong Chrysomela (C. geminata for instance), only much larger. 
Elhaota cuprea. 
E. cuprea, nitida ; elytris lineato-punctatis, interstitiis punctulatis. 
Hab. North China. 
Dark copper-brown, shining; head and prothorax finely punctured, 
the junction of the clypeus with the front marked only by a deep trans- 
verse line, which does not extend to the antennary orbits, the six terminal 
joints of the antenne broader than the others ; scutellum triangular, its 
sides slightly rounded ; elytra oblong, rather broader than the prothorax, 
lineate-punctate, the punctures rather small, oblong, and occasionally 
approximate, the intervals between the lines remotely and minutely 
punctate ; body beneath dark copper-brown, shining; posterior tarsi 
with the basal joint nearly as long as the rest together, the claw-joint 
not longer than the second and third together. Length 43 lines. 
Navres [Cnodaline]. 
Caput retractum ; clypeus fronte confusus. Labrum transversum. Man- 
dibule apice integre. Palpi mavillares securiformes ; labiales art. ult. 
magno, cyathiformi. Mentwn quadratum. Labiwm magnum, basi 
angustiore. Antenne gyaciles, art. tertio longiore, 4-7 equalibus tenu- 
atis, 8-10 elongato-obconicis, ultimo oblongo oblique truncato, Pro- 
thorax transversus, apice leviter emarginatus, basi sublobatus. Elytra 
oblonga, prothorace paulo latiora ; epipleure@ postice abrupte angustiores,
