1-AMILV CURCULIONIDAE

down into the sapwood to oviposit. The egj^ galleries were in no case 

 complete, but after entering the sapwood the female curved her tunnel to 

 one side or the other. I do not know whether the tunnels reach the 

 heart-w'ood. I took the beetle subsequently plentifully at Kachugaon in 

 Goalpara in the middle of May of the same year in the timbers of a 

 bungalow built of sal-wood. It had evidently issued to oviposit in fresh 

 wood. 



HlMATIUM. 



Himatium asperum, Marshall, sp. nov. 

 Reference. — Marshall, A)n!. M<ig. Nat. Hist. Aug. (p. 189) 1913. 



Habitat. — Goalpara, Assam. 



Tree Attacked. — Sal {Shorca vobusta). Kachugaon, Cioalpara. 



Beetle. -Small ; highly punctate, unifonii red-brown, with stout 

 pale setae. Klytra with the pubescence arranged in longitudinal 



rows on the striae. Under-surface mode- 

 Description, rately shining brown to brownish black, 



covered with a sparse golden stiff pubes- 

 cence. Head very convex, strongly punctate, the rostrum short and 

 thick ; about twice as long as broad, straight, almost cyhndrical, 

 mostly covered with coarse and longitudinally confluent punctures. 

 Antennae brown, the club pubescent. Prothorax nearly half as long 

 again as broad, widest near base, gradually narrowed anteriorly, with 

 a deep constriction near apex ; coarsely reticulate-punctate. Elytra 

 very strongly striate-punctate, the punctures large ; the intervals 

 not broader than the striae, and each bearing a row of stout recum- 

 bent overlapping setae, the alternate intervals also with a row- of 

 erect scale-like setire. I'nder-surface punctate. Length, 2.5 mm. to 

 3 mm. 



Some specimens of this small beetle were taken in the middle of May 



from beneath the bark of a large green sal-tree felled in 



Life History. the Kachugaon forests three days before. The insects 



were taken from the upper part of the stem, which had 



commenced to die, apparently from strangulation by creepers, the upward 



flow of sap being much reduced. The beetles were ovipositing in the 



sapwood and inner bark.
