new Genus of Asiatic Curculionidse. 247 



scutellum ; the faint transverse carina 

 on the rostrum that limits the inter- 

 scrobal area behind straight or only 

 slightly angulated. 



3 ( 1). The carina and furrows on the rostrum 



well developed; the shoulders of the 

 elytra obtusely angulated and promi- 

 nent; the spiculum of the male geni- 

 talia very slender, no thicker than the 

 struts of the median lobe fecc, Fat. 



4 ( 3). The furrows on the rostrum very shallow 



and the carina? much reduced ; the 

 shoulders rounded and much less pro- 

 minent ; the spiculum stout, nearly 

 three times as broad as the struts .... deceptor, sp. n. 



5 ( 2). Colour uniformly green ; the transverse 



carina on the rostrum strongly angu- 

 lated and the furrows deep himalayanus, sp. n. 



6 ( 1). Joint 2 of funicle equal to or a little 



shorter than 1. 



7 (12). The scaling on the intervals of the elytra 



broken up by irregular bare transverse 

 lines. 



8 ( 9). The distance between the two discal 



carina; on the rostrum at the base but 

 little greater than the space between 

 each carina and the eye nearest to it, 

 the central carina indistinct and hidden 

 by scales; strite on the elytra quite 



straight and regular marmoratus, Fst. 



it ( 8). The distance between the carinas at least 

 twice as great as that between each 

 carina and the adjacent eye; the cen- 

 tral carina distinct and bare ; some of 

 the striae on the elytra rather wavy or 

 irregular. 



10 (11). Rostrum evidently shorter than its basal 



width and slightly widened at the 



apex armiyer, Fst. 



1 1 ( 10). Rostrum almost as long as its basal width, 



gradually narrowed from base to apex, 



its sides quite straight turkestanicus, Fst. 



12 ( 7). Scaling on intervals of elytra continuous. 



13 (14). Colouring grey or brown ; shoulders pro- 



minent, the humeral slope forming a 

 well-marked angle with the side of the 

 prothorax mast.tts, sp. n. 



14 (13). Colouring uniform metallic green ; shoul- 



ders reduced, the humeral slope form- 



ing almost a continuous line with the 



side of the prothorax. 

 lo ( 16). Punctures in the strhe of the elytra very 



fine and close ; apical spines of tibine 



pale ; the two basal joints of the funicle 



equal huhmirentis, sp. n. 



1G (15). Functures on the elytra rather widely 



spaced ; apical spines of tibiic dark ; 



joint 1 of funicle a little longer than 2. sjostedti, sp. n.
