2 . The terminal tooth of the frout tibia forms a long blunt 

 Jobe, aud the pygidium is scarcely convex and rugosely punctured 

 to the apex. 



Length, 9-10 mm. : breadth, 5".5-6 mm.

Popillia gemma, Newm., Mag-. Nat. Hi.st. (2) iii, 1839, p. 3tJC ; Hope, 

 Trans. Liun. Soc. xiii, 1840, p. 596, pi. 40, fig. 4. 



Popillia metallicollis, Fairm.,* Ann. Soc. Ent. Belg'. xwi. 1887, 

 p. 113 (n. syn.). 



Deep metallic crimson, with the elytra and femora reddish 

 testaceous, the former having a large pale anterior patch 

 enclosing the scutellum and vaguely defined behind. 



It is rather sliort and rliomboidal in shape and not very convex 

 above. The clypeus is sliort, broad and rugose, and the forehead 

 is strongly and closely punctured. The pronotum is very shining 

 and minutely punctured, except at the sides, which are moderately 

 coarsely punctured. The lateral margins are angulated before 

 the middle and nearly straight from there to the front and 

 hind angles, of which the frout ones are acute and the hind 

 well-marked, but slightly obtuse. The scutellum is minutely 

 punctured, and the elytra have each five deep punctured strife, 

 the second and fourth intervals being broad and each having 

 an irregular line of punctures along the middle; the external 

 margin is flattened behind the shoulder. The pvgidium is 

 decorated with a large transverse patch of decumbent pale 

 hairs at the base on each side, and the apical part is thinly clothed 

 with erect hairs. The mesosterual process is strong, broadly 

 •compressed and not sharp. The sides of the sternum and abdo- 

 men are clothed with coarse and moderately closelj'-set pale hairs. 



S . The front tibia is broad, witii two short sharp teeth at the 

 end, the inner front claw is broad and deeply clett and tiie outer 

 middle one long and entire. The legs are stout and all the tarsi 

 rather short and thick. 



$ . The four anterior legs are slender and the terminal tooth 

 of the front tibia long and cur\ed. 



Lem/th, 9-11 mm. ; breadth, 5*5-tr5 mm. 



Assam : Bhutan ; S.W. China : Yunnan. 



Type not traced : that of P. metaUicuIJis in the Paris Museum. 



This very greatly resembles P. cupricoUis, Hope, but seems to 

 he more constant. It is smaller and recognisable bv the lio-ht- 

 coloured area at the base of the elytra and the flange on each side.
