 no observations seem to have been previously recorded on its life history.

Beetle.— Stout, elongate, brown, rather shining, punctate. Prothora.K wider than 

 long. Scutellum heart-shaped. Elytra broadest in apical fourth, where they are much 

 broader than prothorax ; apices separately rounded, suture often slightly gaping at apex ; 

 pygidium exposed ; tibiae spined. Length, 20 mm. to 25 mm. 



Larva.— White, curved, crmkled, with prominent head, stout mandibles, and three pairs 

 of rather long legs. 



This insect is very abundant in the Darjeeling forests and tea gardens, 

 and is found throughout the Sikkim forests in the 



Life History. Kalimpong Division. The beetle appears on the wing 



from the end of March through April into May. The 

 larva feeds on the roots of the tea and garden plants, and not improbably 

 on the roots ofseedlings of forest trees as well. In 1883 the grubs committed 

 great havoc in the public gardens at Darjeeling, over two and a half millions 

 of individuals having been collected. In i8gi the insect again made its 

 appearance in the Darjeeling district, and killed off a large number of 

 plants in the tea-garden nurseries. The full life history does not appear 

 to have yet been worked out, but it is improbable that it passes through 

 more than one life-cycle in the year.
