FAMILY CERAMBYCIDAE 



Undei -surface dark brown to black, punctate ; abdominal segments reddish brown, with a close 

 fine white pubescence. Legs brown, lower two-thirds of thickened femora black. Antennae 

 damaged. Length, 15 mm. ; breadth, 3.5 mm. 



This beetle was taken from beneath the bark of an Anogeissus Unifolia

 the beetle appearing on the wing some time during that month,

Habitat. — Assam ; Goalpara. 



Tree Attacked. — -? Sal {Shorca robusta). Kachugaon, Goalpara, Assam. 



Beetle. — Stout, thickset, and robust, with long powerful legs, A brilliant green with 



reddish markings. The antennae have a few whorls of hair (circular brushes) on them. Under- 



surface brilliant red. Thorax ridged, produced into a blunt point 



Description. medianly at the sides, smooth. Elytra with well-marked shoulders, 



thickly punctate ; a circular brush of black hair arises from middle on 



the basal third and a small transverse one at same level near lateral margin ; a transverse 



black band of hair on the middle and apical thirds ; legs shining indigo-green. Length, 



1 1 in. The beetle is figured in hg. ly. 



This extremely handsome cerambycid was taken plentifully on the wing 



in the Kachugaon sal forests in Goalpara during May. 



Life History. It flies by day, settling in the sunlight upon the bark 



of green standing or felled trees. The beetle was 



pairing between 13 and 23 May. I was unable to ascertain definitely 



where this insect came from. It may, as Mr. Perree suggests, lay its eggs 



on the sal, and the grubs may feed in the tree. I myself, however, think it 



possible that it may prove to be a sal girdler, girdling the branches or 



leaders of young saplings and laying its eggs in the part girdled. Its life 



history requires working out.

Tree Attacked. — Wrightia tinctoria. Madras. 



Beetle.- Elongate, rather narrow, easily recognized by the 

 great resem1)lance of the upper surface to the decaying ligneous 



strands of rough bark. General colour 

 Description. yellow with longitudinal dark brown or 



brownish black stripes, the basal portion 

 of prothorax and elytra a rich velvety dark brown or black ; the 

 extraordinary coloration of the beetle is due to the thick 

 pubescence which clothes the whole surface, upper and lower, 

 with the exception of smooth black finely punctate areas on the 

 abdominal segments ; the pubescence appears in the form of long
