 the middle with a broad fulvous vitta ; legs and under surface of the 

 body clothed with adpressed hairs ; abdominal segments thickened. 



This species belongs to the 2nd section of the genus. 



Genus Pseudodera. 



Corpus elongatum, convexum. Caput exsertum, dorso pone ocidos con- 

 Btrictum, facie sat declive, inter oculos in carinam latam dorso cana- 

 liculatam, cujus ad latera antenna) inserts) sunt, producto; antemis 

 robustis, corporis longitudini fere requalibus, apicem versus paullo au- 

 gustatis, articulis 1™° curvato, basi ad apicem incrassato, 2^o brevi, 

 3tio-10ra° singulis ad apicem incrassatis ; labro transverso ; mandibuUs 

 arcuatis, apice dentatis; mento quadrato; ligula erassa, obtusa; palpis 

 mazillaribus articido prime parvo, secundo paullo elongate, subclavato, 

 ultimo breviter ovato, acuto ; oculis ovato-rotundatis, prominulis. Thorax 

 transverso-quadratus, dorso valde convexus, ante basin transversim 

 sulcatus, sulco utrinque linea impressa longitudinali brevi terminato. 

 Elytra oblonga, bifariam striato-punctata. Pedes robusti, antici sub- 

 elongati, cseteri longitudine perparum paullo decrescentes ; femoribus 

 paullo, posterioribus evidentius incrassatis; tibiis simplicibus, dorso non- 

 canaliculatis, apice paullo incrassatis ; tarsix tibiarum apici insertis, 

 articulo basali duobus sequentibus longitudine fere sequali, unguiculia 

 appendiculatis. Prostenimn angustatum, distinctum. 



Type Pseudodera xanthospda, Baly. 



Very closely allied to Crepidodera, but divided from that genus by 

 the tapering antenna} and by the constriction of the upper surface 

 of its neck. The transverse groove also at the base of the thorax 

 terminates just within the short longitudinal grooves, not being 

 continuous with them as in Crepidodera. 



Pseudodera xanthospUa. 



P. elongata, modice coiivexa, subparallela, postice attenuata, rufo-fulva, 

 nitida; oculis, anteuuis, tibiis tarsisque nigris; elytris gemellato-punc- 

 tato-striatis, utrisque plaga submarginali, ante apicem posita, pallide 

 llava. — Long. 3A-4^ lin. 



Hab. Northern China. 



Antennae inserted between the eyes on an elevated space, the centre 

 of which is traversed by a longitudinal groove : thorax smooth, im- 

 punctate, convex, basal groove deeply impressed, slightly angular, and 

 having a shallow longitudinal impression running upwards on the disk 

 from its apex ; it is terminated at either end by a short deep longi- 

 tudinal groove: elytra not wider than the thorax, parallel, narrowed 

 near the apex, their surface smooth and shining ; disk of each impressed 

 with eleven rows of distinct punctures, the first abbreviated, tin. » eond
