Key to the Species. 



1 (4) Rostrum much shortex* than the head 



aud gradually dilated from base to 

 apex. 



2 (3) Rostrum only slightly broader than 



long ; club of anlenua3 darker than the 

 rest; elytra with stiff erect curved 

 setae ; scaling uniformly pale green . . chloris, sp. n., p. 353. 



3 (2) Rostrum nearly twice as broad as long ; 



club of antennfe not darker ; elytra 

 with recumbent setse ; scaling uni- 

 formly grey cineretis, sp. n., p. 853. 



4 (1) Rostrum as long as the head, narrowed 



from the base to about the middle and 

 slightly dilated thence to the apex. 



5 (6) Elytra with recuuibent setre pleheins, sp. n., p. 354. 



6 (5) Elytra with erect curved sette hispidulus, sp. n., p. 354. 



333. Hyperstylus chloris, sp. n. 



Colour ferruginous, with uniform dense pale green scaling 

 above and below. 



Head as long as broad, tbe eyes only slightly convex. Rostrum 

 shorter than the head, slightly broader than long, gradually 

 dilated from the base to the apex, the space between the scrobe 

 and the eye very small ; the upper surface plane and with a fine 

 central stria. Antennoi flavous, a\ ith tbe clnb darker. Prothorax 

 broader than long, the sides slightly rounded, broadest a little 

 behind the middle, the apex not narrower than tbe base, the 

 sculpturing hidden by the dense scaling. Scutelhim unicolorous 

 with the elytra. Eh/tra rather broad, slightly convex longitu- 

 dinally, and with short ei-ect pale seta3. Legs uniformly flavous, 

 the femora not darker. 



Length, "2-2^ mm. ; breadth, |-1^ mm. 



Punjab : Ivangra Valley, 4500 ft. {G. C. Dudgeon). 



Type in the British Museum. 



Very similar in size, shape and colour to the type species, H. 

 jndhpes, Eoel., from Japan ; but that species has the rostrum not 

 broader than the forehead, the scrobes much more closely approxi- 

 mated, the eyes prominent and the elytra without erect setae. 



334. Hyperstylus cinereus, sp. nov. 



Colour black, with uniform dense grey scaling above and below. 

 Closely alhed to H. chhris, but differing as follows : — 



Head broader than long, the eyes more convex. Eostrvm much 

 shorter, nearly twice as broad as long, Antennce uniform! v flavous. 

 Elytra with recumbent seta?. Legs flavous, with the thickened 

 part of the femora darker. 



Length, 2-2| mm. ; breadth, j-l-g- mm.
