tate ; elytra closely and deeply punctured ; pygidium black, marked in 

 tlie 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 Pseddodeka. 



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

 strictum, facie sat declive, inter ocidos in carinam latam dorso cana- 

 licidatam, cujus ad latera antennae insertse simt, producto ; antennis 

 robustis, corporis longitudini fere sequalibus, apicem versus pauUo an- 

 gustatis, articulis Imo cm'vato, basi ad apicem incrassato, 2do brevi, 

 3tio-l0mo singulis ad apicem incrassatis; lahro transvei-soj mandibulis 

 arcuatis, apice dentatis; mento quadrato; ligaJa crassa, obtusa; palpis 

 maxillarihis articulo piimo parvo, secundo paullo elougato, subclavato, 

 ultimo breviter ovato, acuto ; ocidis ovato-rotimdatis, prominulis. Thorax 

 transverso-quadmtus, doi"so valde convexus, ante basin transvei-sim 

 sidcatus, sulco utrinque linea impressa longitudinali brevi terminate. 

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

 elongati, caateri longitudine perparum paullo decresceutes ; femoribus 

 paullo, posterioribus e\ddentius incrassatis 5 tibiis simplicibus, dorso non- 

 canaliculatis, apice paullo incrassatis ; tarsis tibiarimi apici insertis, 

 articido basali duobus sequentibus longitudine fere eequali, zaif/uiculis 

 appendiculatis. Prosternum angustatum, distinctum. 



Type Pseiidodera xanthospila, Baly. 



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

 the tapering antennae 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 xanth ospUa . 



P. elongata, modice couvexa, subparaUela, postice attenuata, rufo-fidva, 

 nitida ; ocidis, antennis, tibiis tarsisque nigris ; elytris gemellato-puuc- 

 tato-striatis, utrisque plaga sul^marginali, ante apicem posita, pallide 

 flava. — Long. 3i-4i lin. 



Hah Northern China. 



Antennae inserted between the eyes ou 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 rimning upwards ou 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 eacli impressed 

 with eleven rows of distinct punctiues, the first abbreviated, the second
