smooth and convex. The pygidium is convex and rather coarsely 

 transversely strigose. The raesosternal process is moderately long 

 and slender, not flattened. The tibiae are stout, and the two teeth 

 of the front tibia short and close together. 



c? . The front tibise are very broad, and the two teeth minute 

 and sharp. 



$ . The terminal tooth of the front tibia is blunt and spatulate 

 and the hind tarsi are very short and thick. 



Length, 13-14 mm. ; breadth, 8 mm.

The type in the British Museum and a specimen in the Oxford 

 Museum (from the Miers Coll.) are labelled " India " alone, while 

 one in the Berlin Entomological Museum is said to have come 

 from Assam.

 Popillia marginicollis, var. atrata, Kraatz, 1. c. 



Deep metallic green or golden green, with the clypeus, the 

 sides of the pronotum, the elvtra, the extremity of the abdomen 

 (generally) and the legs and antennae reddish orange with a 

 metallic lustre (generally very slight or absent upon the elytra, 

 except along the suture) ; the hind tibiae and the tarsi generally 

 darker in colour than the remainder of the legs. 



The body is moderately short, broad, and not very convex above. 

 The clypeus is broad, finely rugose and nearly straight in front, 

 and the forehead is strongly and closely punctured. The pronotum 

 is shining, very minutely punctured, except near the front angles, 

 with the lateral margins strongly angulated before the middle and 

 nearly straight to the front and hind angles, of which the former 

 are acute and the latter well marked but obtuse. The scutellum 

 bears a few punctures. Each elytron bears five deeply impressed, 

 regular and equidistant striae, finely punctured at the bottom. 

 The intervals are smooth, slightly convex and quite unpunctured. 

 The sides bear less regular rows of strong punctures and are 

 without abrupt flanges. The pygidium is coarsely transversely 

 striolated, and at the apex very convex. There are two small 

 roundish patches of white hairs at the base of the pygidium and 

 scattered hairs at the sides, and the sides of the sternum and of 

 the abdominal segments are rather densely clothed with similar 

 hairs, those of the latter in double series. The mesosternal pro- 

 cess is moderately long, but not very sharp and not compressed. 

 The two teeth of the front tibia are minute and placed close 

 together at the extremity.
