ridge, but the posterior part between the eyes is produced into a 

 short, erect laminate process vertical from base to middle and 

 triangular thence to the apex, where it curves slightly forward ; 

 in the smaller development the lamina is simply triangular from the 

 base, the head is plicate rugose at apex, densely punctate in the 

 centre, more remotely punctate in the posterior part and at the base 

 of the laminate process, and more broadly and more deeply punctate 

 on the genae ; prothorax closely granulate, but the median posterior 

 part is deeply and closely punctate, the sides of the posterior part 

 are sinuate, the base marginate ; in the great development the 

 median anterior part is strongly declivous and has an arcuate not 

 much raised ridge which is emarginate in the centre, the declivous 

 part being weakly punctate ; in the smaller development the prothorax 

 is simply and normally sloping, the median posterior part bears more 

 or less distinct traces of a longitudinal groove ; elytra with the suture 

 shiny, narrowly geminate striate with very shallow transverse punc- 

 tures, the intervals very closely granular except in the dorsal part 

 of the first two intervals where the granules are partly obliterated ; 

 pygidium covered with rough, sub-contiguous punctures ; sternum 

 punctate ; femora very closely punctate ; metasternum with a furrow 

 reaching nearly from base to apex. 



Length 10-12A- mm. ; width 6-8 mm.

" Moderately shiny, obscurely bronze-green with the elytra and 

 the pygidium more obscure, glabrous above, sides of prothorax and of 

 elytra, and also the pygidium briefly flavous pubescent. Head closely 

 punctate, not carinate, depressed transversely between the eyes and 

 provided past the line of the eyes with a short, erect small lamina ; 

 clypeus projecting, narrowed, reflexed and truncate in front; 

 prothorax granulate, strongly and densely asperate punctate in the 

 posterior half of the disk, and bearing nearly in the middle of the 

 disk a transverse,, erect, rounded or triangular transverse lamina, 

 sides strongly sinuate behind ; base marginate and finely carinate on 

 each side along the basal margin ; elytra broadly striate, intervals 

 plane, somewhat finely and sparsely granulate towards the suture, 

 and getting larger and denser towards the sides ; pygidium densely 

 granulate. 



Length 11-13^ mm."
