ct:piialodonta. 12!) 



rdg'c dilated and continuous with the apieal margin of the elytron , 

 sides straight, indistinctly margined ; apex obtusely rounded, 

 apical margin (Tah. IX. fig. 12) dilated, truncate ; above flattened 

 along the back, convex on the sides ; shoidders produced obliquely 

 outwards and upwards into a stout process, the apex of which is 

 obhquely truncate and armed with two short stout teeth, the 

 inner one longer than the other ; surface deeply and regularly 

 punctate-stiiate, second and fourth interstices from the suture 

 shining, subcostate, alternate interstices on the outer disc indi- 

 stinctly elevated, suture also subcostate ; dark metallic green, each 

 elytron with eight bright fulvous spots : one at the base ; a second 

 below the seutellum, common ; two placed obhquely below the 

 hiimeral process, subconflueut ; two below the middle on the outer 

 border, also oblique and subconfluent ; another attached to the 

 suture, parallel with the last, obliquely transverse ; and the eighth 

 transverse, on the apical border, extending from the suture to the 

 apex of the lateral spine. Beneath shining rufous ; legs moderately 

 robust, subelongate, anterior pair rather longer than the others.

C broadly elongate, scarcely dilated behind, subdepressed ; fiilvous. 

 three vittfe on the thorax and the elytra obscure rufo-fuscous 

 with a metallic green reflexion ; each eh'tron with eight pale ful-

 with a short stout spine, its apex obtuse ; vertex impressed with a 

 longitudinal fovea ; antennae subincrassate, second joint rather 

 longer than the first, four terminal joints elongate, slightly in- 

 crassate, forming nearly half the length of the antenna) ; eyes 

 black. Thorax narrowed from the base to the apex ; sides nar- 

 rowly margined, sKghtly angled near their middle, more narrowed 

 in fi-ont, anterior angles produced into a stout subacute tooth ; 

 above subconvex, convex on the sides, transversely depressed near 

 the base, basal lobe deflexed ; deeply punctxu-ed, a central longi- 

 tudinal stripe, and one on either side, close to the lateral border, 

 rufo-fuscous with a metallic reflexion. 8euteUum smooth, im- 

 pimctate. Elytra broader than the thorax, slightly dilated behind ; 

 sides narrowly margined, posterior angles produced obliquely out- 

 wards into a large flattened spine, ciu'ved on the outer edge, its 

 apex acute, scarcely extending backwards beyond the apical mar-
