FAMILY CERAMBYCIDAE 277 



slightly raised glossy spaces near the middle. Klytra more than twice as long as broad, 

 dull ; finely rugulose and \'ery minutely punctulate. Thorax beneath rather thickly covered with 

 long tawny hairs, abdomen with very short sparsely scattered hairs. Last ventral segment 

 sinuate at apex. 



$ Antennae much shorter (see fig. 189). Abdomen glabrous, the last ventral segment 

 with rounded hind margin. Length, 36-46 mm. ; breadth, 11-17 mm. 



I am of opinion that this insect infests the Kharshu oak in the Western 



Himahiya. I have taken the beetle on oak trees of this 



Life History. species towards the end of June, and lonj^icorn grubs of 



large size, and resembling the grubs of this group of 



the Cerambycidae, infest this tree.

Referenxe. — Gahan, F.B.I. Ceramb. vol. i, no. 15, p. 16 (1906). 



Habitat. — Fort Sandeman, Baluchistan. Gahan in Fauna gives Balu- 

 chistan (near Quetta) (C. Elliott) ; Fort Sandeman (Capt. James). 

 Tree Attacked. — Poplar ? 



Beetle. — Resembles the last in having the heavily jointed antennae with the long side 

 prolongations to joints. Only the male insect appears to be known. Black above; antennae, legs, 



and body beneath pitchy brown ; tarsi reddish brown. Head im- 

 Description, pressed with a median groove less distinct behind. Antennae 



scarcely extend beyond middle of elytra, joints third to eleventh each 

 with a long process projecting oblicjuely ; third about one-third longer than first, and twice 

 as long as fourth, its process half as long as joint itself ; fourth to eleventh sub-equal in 

 length, the ramus of each much longer than stem ; twelfth nearly twice length of eleventh. 

 Prothorax with two spines on each side — one short at anterior angle, the other long and 

 slightly recurved just before the middle. Elytra less than twice as long as broad. Breast 

 thickly covered with long greyish hairs ; the abdomen with some shorter sparsely scattered 

 hairs ; third joint of hind tarsus cleft in middle. Length, 33 mm. ; breadth, 13 mm. 



This insect was apparently first taken near Quetta by Mr. C. Elliott, 



late Conservator of Forests (then Deputy Conservator 



Life History. of Forests in Baluchistan). Gahan's original description 



of the species was made from this specimen. The only 



other record of this insect I know is that of Captain James, Officiating 



Political Officer, Zhob, who sent me a specimen of the male beetle from 



Fort Sandeman in January igog. The tree it infests is unknown, but is 



not improbably a species of poplar. 



ACANTHOPHORUS. 



The single species as yet reported from India is one of the largest 

 tree-infesting longicorns known.
