FAMILY SCOLYTIDAE 



I took an individual of this species which came into a bungalow at 

 night, attracted by the light. The bungalow is situated in the Karimponga 

 teak plantation, in the middle of the forest at the foot of the Ootacamund 

 Hills. The insect was captured on 27 August 1902. 



Xyleborus hagedorm, Stebbing, sp. nov. 



REFERENCE. This insect was submitted to Dr. Max Hagedorn, who kindly prepared drawings of the 

 mouth parts, antennae, and fore leg. These I propose to publish with the description in the Indian 

 Forest Memoirs. I have pleasure in naming the species after Dr. Hagedorn. 



Habitat. Tharrawaddy, Lower Burma. 



Tree Attacked. Teak (Tectona grandis). Kadin Bilin Forest, Tharra- 

 waddy. 



Beetle. Elongate cylindrical, stout. Red-brown, shining, the prothorax anteriorly, elytra 

 apically and laterally, darker in colour ; rather densely pubescent except on disk of prothorax 



and on basal part of elytra. Front of head moderately convex, 

 Description. uniformly and finely punctate ; a fringe of long yellowish setae over 



mouth ; antennae reddish, club yellow. Prothorax with base straight, 



basal angles oblique, sides and apex strongly rounded ; the anterior half strongly covered 

 with large and close transverse asperities, largest and densest on anterior margin ; these 

 asperities stretch backwards on lateral surfaces to the basal angles ; on disk the asperities 

 are replaced by transverse striae which reach to the highest point of disk, which is 

 situated behind the middle ; rest of surface depressed to base, shin- 

 ing, and very finely and sparsely punctate. Scutellum transverse. 

 Klytra more than half as long again as thorax, slightly wider at base, 

 sides nearly straight, apex rounded ; finely and regularly punctate, 

 the punctures placed in rows and consisting of two kinds round 

 shallow ones in rows, and in the intervals a double row of smaller 

 and deeper punctures, each containing one or more setae ; a longi- 

 tudinal shallow depression on either side of suture ; declivity rather 

 oblique, upper part punctate, lower portion with asperities ; one or 

 two longitudinal depressions down declivity, the surface rather 

 densely covered with long spiny yellow hairs, densest on lowest 

 portion. Under-surface darker in colour, finely punctate and pubes-

Xyleborus hage- 



ctorui, Steb., sp. nov., 



in Teak. Lower Burma. 



This scolytid infests the leading shoots of young teak saplings. 



Whilst inspecting a young plantation in Tharrawaddy 



Life History. on 25 January 1905 I noticed a number of dead 



shoots, and inspection showed that they had each been 



tunnelled by an insect, the tunnel being carried up the centre of the shoot. 



The female tunnels into the shoot, girdling it in part, and perhaps 



occasionally entirely. She then lays an egg near the centre above the 



partial girdle. On hatching, the grub eats out a gallery in the heart of 



the shoot, tunnelling upwards and killing the portion above where the egg 



On reaching full size it pupates at the top of the tunnel. When 



eats its way out of the shoot by a horizontal tunnel 



carried to the outside.
