POP1LLIA. 79 



behind the shoulder of each elytron. The pygidium is extremely 

 smooth and shining, very minutely and scantily punctured, except 

 at the sides and apex, where the punctures are rather coarse ; 

 there are also scanty grey hairs in the same parts and two patches 

 of decumbent hairs at the base. The sides of the sternum and 

 the posterior half of the sides of the abdominal segments are 

 raiher thickly clothed with coarse whitish hairs. The meso- 

 sternul process is short, blunt, and compressed. 



c? . The two teeth of the front tibia are acute, and the pygidium 

 is very prominent and feebly longitudinally impressed at the apex. 



$ . The apical tooth of the front tibia is long and blunt, and 

 the pygidium is deeply excavated at the apex, the cavity being 

 smooth and shining. 



Length, 11-liJ mm.; breadth, 6-7 mm. 



ASSAM : Shillong (F. W. Champion), Khasi Hills, Cherrapunji,. 

 Nongpriang (B. Warren, May); SIKKIM (type). 



Type in Dr. F. Ohaus' collection. 



52. Popillia caerulea. 



Popillia ccerulea, Boh., Eugen. Resa, 1858, p. 55. 



Blue-black or green-black, sometimes with the elytra entirely 

 black. There are scanty erect greyish hairs on the forehead and 

 a very few near the lateral margins of the pronotum, two rather 

 loose and inconspicuous patches at the base of the pygidium, 

 and a thicker clothing upon the legs and the sides of the body 

 beneath. 



The body is rather globose, compact and convex. The head is 

 densely rugose and the clypeus broadly rounded. The pronotum 

 is coarsely and closely punctured, except in the posterior median 

 part, where the punctures are fine and scanty. The scutellum is 

 distinctly punctured. Each elytron bears five rather broad and 

 coarsely punctured dorsal striae, with the subsutural interval 

 rather broad and smooth, except at the base, and there is a deep 

 i'ovea before the middle. The pygidium is convex and coarsely 

 punctured at the sides. The mesosternal process is broadly 

 compressed, blunt and very little produced. The middle of the 

 metasternum and abdomen are smooth. The front tibia is rather 

 strongly bidentate. 



cJ . The pygidium is very convex, and the front tarsus short 

 and thick, with a very broad inner claw. 



Lenyih, 9-12 mm. ; breadth, 5-7'5 mm. 



BURMA : Maymyo (H. L. Andreives, May), Kuby Mines 

 ( W. Doherty) ; S. CHINA ; HAINAN ; FORMOSA. 



This is a common and widely-distributed Chinese species. I 

 have seen specimens from Formosa determined by Kraatz as 

 Popillia semicenea, Kr., but although superficially very like that 

 species, it is different, having a blunter and shorter sternal 

 process and less close and definite hair-patches on the pygidium.
