FAMILY ANTHRIKIDAE 



Fig. 259. 

 A)iihribid. 

 Tenassei'Im. 



Beetle. — Elongate, rather narrow. ])lack, mottled with small patches 

 and spots of a whitish pubescence placed in tufts on thoiax and elytra. 

 Head sloping, the rostrum short and square, 

 Description. densely pubescent above ; the vertex coarsely 



rugose. Prothorax widest behind, sides rounded ; 

 coarselv rugose-punctate and covered with a short close brown pubes- 

 cence with short tufts here and there of a whitish pubescence. Elytra 

 slightly wider than thorax at base, constricted apically ; punctate, the 

 punctures deep, rather far apart in longitudmal rows, the interspaces 

 moderately shining, covered, especially laterally, with the short rather 

 dense brown pubescence, interspersed with large patches and tufts of 

 longish white pubescence. Pygidium dark brown. Legs black, with 

 patches of white pubescence. Length, 10.5 mm. 



I cut out a specimen of this insect from a gallery in the sapwood of a 



large felled pyinkadu-tree in the compound of the 



Life History. Natchoung bungalow. The tunnel in the wood led from 



an elongate broad gallery made by the larva in the 



bast and sapwood. The beetle was mature when it was taken from the 



tree in the middle of March 1905. 



Anthribid. 



Reference.— It has not proved possible to obtain the identification of this insect. 



Habitat. — South Coimbatore, Madras. 



Tree Attacked. — Bamboo {Doidroctjlajinis strictus). Mount Stewart, 

 Scnith Coimbatore. 



Beetle.— Resembles the last. Head with a stout moderately 



long rostrum, widest medianly and densely pubescent, antennae 



inserted in front of eyes half-way up ros- 



Description. trum ; vertex shining, punctate. Black, 



the protliorax with a scattered, the elytra 



a dense, yellow pubescence, placed anteriorly on prothorax and in 



patches and tufts on elytra. Prothorax slightly widest medianly, 



sides curved ; punctate, punctures large, confluent or mixed with 



transverse striae posteriorly. Elytra with apices separately rounded, 



the sides straight to posterior coxae, thence constricted ; punctate- 



striate, punctures large, but almost hidden beneath the dense 



pubescence ; the pubescence is densest laterally and apically, and 



consists of short dark yellow hairs and long whitish yellow ones 



which appear in tufts in basal part in a transverse band in apical 



three-fourths and in patches in apical fourth. Under-surface with 



a short dense pubescence. Antennae long and slender, black. Legs black, pubescent, the 



third tarsal joint large. Length, 11.5 mm. 



A specimen of this anthribid was taken from a chamber in the wood of 



a Dcndrocalainus strictus bamboo. Fi"om an e.xamination 



Life History. of bamboos in the Mount Stewart forests it appeared 



that the eggs are laid at the junction of a branch with 



the mam stem of the bamboo, and that the grubs feed in the wood at this 



spot. Many bamboos were noticed to have been infested in this manner. 



Only one mature beetle was, however, taken towards the end of July 1902, 



and no larvae were found.
