FAMILY CERAMBYCIDAE 



341 



Beetle.— Chestnut brown in colour, more or less nitid, sparsely furnished above with short 

 semi-erect fulvous brown hairs. Head and basal joints of antennae finely rugulose-punctate. 



Trothorax closely and rather strongly punctured ; marked with a 

 Description. feeble sinuate groove or depression near the apex and another near 



the base ; the disk slightly depressed along the middle with a very 

 narrow impunctate space behind. Elytra closely and strongly punctured, less strongly near 

 the apex. Body beneath reddish brown, sparsely pubescent, less closely and rather finely 

 punctured ; prosternum transversely depressed a little behind the front margin ; abdomen 

 narrowed posteriorly, first segment longest, second to fourth successively shorter. Legs 

 reddish brown, minutely and sparsely punctate. {Descr. after Gahaii.) Length, 11 mm. to 

 13 mm.; breadth, 3^ mm. to 4 mm. 



Young Larva.—The young larva is a tiny wliitc grub of about half an inch in length with 

 a large prothorax, 

 brownish weak man- 

 dibles, and narrow 

 body segments (tig. 

 231, rt). 



Full-grown Larva. 

 — White to whitish- 

 yellow in colour, with 

 a brown head and 

 powerful black man- 

 dibles. The prothorax 

 is greatly enlarged and 

 is hard. The succeed- 

 ing segments are 

 rather corrugated, ta- 

 per posteriorly. Seg- 

 ments 2 to 10 have 

 each a stigma placed 

 laterally near the ven- 

 tral surface. Length, 

 25mm. (fig. 23i,(!i, (^i). 



Pupa. — The pupa 

 is elongate, white to 

 whitish - yellow in 

 colour, and has the 

 appearance to some 



extent of the future beetle. The antennae are pressed against the sides and the legs and 

 wings against the chest. Fig. 231, <:i, c shows the pupa natural size and enlarged.

In 1901 I found trees of this species infested with 

 both buprestid and longicorn grubs in Bashahr.* The following year at 

 Pajidhar in Jaunsar in a recently felled large green deodar I took on 

 24-28 June young buprestid and longicorn larvae, some perhaps a fortnight 

 old, others probably but a couple of days old.
