which appears on the elytra in three bands. Eyes large. Rostrum 

 Description. as long as head and prothorax together, moderately curved, slightly 



thickened at insertion of antennae, shining at the tip ; antennae thin, 

 inserted about two-thirds up rostrum, and about same length as latter, scrobes short. Prothorax 

 lightly punctate, with a deep impressed line at base. Elytra about twice the length of prothorax, 

 much wider, convex, striate-punctate. In <J the rostrum is more punctate and reddish in upper

This weevil was discovered by Mr. C. Gilbert Rogers, I.F.S., infesting- 



the common fodder plant termed Kibu {Strobilanthus 



Life History. pcctinatiis), which is to be found in Sikkim at elevations 



of 6,000 ft. and thereabouts. The grubs feed on the 



seeds, completely destroying them. Mr. Rogers first took the beetle in the 



rains of i88g.

off the leaves of the mango near their bases, and 



thus defoliates the trees."
