both ^ and $ — as above described or normal, with the 

 apex simple, acute, or spinose. 



P. 'paragiiayaids, n. sp. 



(J. Ovoid, convex, chestnut-brown, moderately shining ; clypeus 

 strongly and sinnately narrowed to the front, which is rounded, 

 entire and recurved ; closely rugose punctate ; head not closely 

 punctured, the triangular depression well marked : thorax evenly 

 rounded at the sides, widest at the middle, distinctly but not very 

 closely punctured over the entire surface, a submarginal dark- 

 greenish spot at each side, the front and hind l)orders reflecting 

 green, median basal lobe well marked : scutellum wider than long, 

 sparsely punctulate, the margins reflecting green : elytra expanded 

 behind, the sutural apex simple or acute ; finely, very irregularly, 

 and not at all closely, punctured, and here and there rugulose ; there 

 are also — especially down the disc — a few vaguely impressed lines, 

 which are irregularly punctured ; post-humeral rugosities very faint; 

 a dark spot at the shoulder, and another (always faint, and sometimes 

 wanting) near the side, a little behind the middle : pygidium with 

 the sides dark green, the middle testaceous ; convex and rapidly de- 

 clivous, very delicately aciculate-rugulose on the disc, more strongly at 

 the sides, the ajjex smoother and thinly punctate ; apex subtruncate : 

 under-side shining, greenish : mestasternum entirely punctured, 

 densely so at the sides, wliich are also pilose : abdomen smooth and 

 metallic down the middle, the last segment smooth, and testaceous at 

 each side : legs shining castaneous, the femora little tinged with 

 green : mandibles very strongly excised outwardly and projecting 

 beyond the clypens: prosternal process rather small, the mesosternal 

 short, strongly compressed, subvertical in front. 



5 . Form more broadly ovoid, less convex, and less shining : 

 clypeus but little differing from that of $ : thorax less convex, less 

 rounded at the sides, widest behind the middle, the puncturation 

 stronger ; front and hind borders — and borders of scutellum — not 

 reflecting green : elytra much more distinctly punctate-striate, the 

 dorsal intervals subcostate : pygidium not convex, gradually sloping 

 to the apex, which is narrowly rounded, entirely testaceous-brown, 

 entirely and closely aciculate-rugulose : abdomen dark bronzed-green 

 with purplish reflections (especially at the hind Ijorder of the 

 segments), duller than in the jj, and distinctly punctured ; the last 

 segment of the same colour and sculpture as the pygidium. 



Long. $. 21-5-22 mm. $. 23 mm. Lat. ^. 12 mm. $. 13 mm.
