stems all the year round, so that the insect probably takes at least two 

 years to pass through its various stages. In the Kulsi teak plantation 

 tlie practice that was adopted in 1879 was to coppice all young trees 

 that were badly attacked, and to encourage the growth of the strongest 

 shoot from the stool to form a new tree by removing all other shoots 

 as fast as they appeared. It was found best to leave older and more 

 vigorous trees alone, provided they showed no signs of fading, as in 

 many cases they recovered. 



With the exception of the single specimen from the Knlsi teak plan- 

 tation, the Indian Museum collection contains specimens of Stromatium 

 aaperulum. from the Malay Peninsula only, Stromatium harhatum being 

 the common Indian form. An application, therefore, was made to the 

 Forest Officer of Kulsi for further specimens of the beetle which had 

 been injuring the teak trees. In reply, specimens were forwarded of 

 no less than three very distinct species of Cerambycidse, viz, Stroma- 

 tium harhatum, Neoceramhyx holosericeus, Mgosoma lacertosnm, the species 

 Stromatium aspernhini not being represented. Teak logs said to contain 

 the grubs were also furnished, and an attempt is being made to rear the 

 beetle from them in Calcutta, as it will be interesting to learn the 

 part played by the different species, the probabilities being that most of 

 the damage is due to some one kind of insect. (The figures show the 

 beetle Stromatium asperrilum, with some of the larvae, furnished by the 

 Deputy Conservator, Kamrup.) 



The small Psychid, the cone-like cases of whose caterpillars are com- 

 monly to be found upon rose bushes, LageV' 

 ageis isemia syc i . strcstnia indica bushes, and other ornamental 



shrubs in Calcutta gardens, has been determined by Mr. F.Moore, who 



writes: — ''This moth and its 

 case are identical with a species 

 of Fsychidcs which I have in my 

 collection under the MS. name 

 of Bahula grotei, the type speci- 

 men of which was reared at Ali- 

 pur by the late Arthor Grote from 

 cases found upon the Babul.''^ 

 The following description of the 

 species has been kindly furnished 

 by Mr. Moore : — 



"Bahula grotei, — upper and 



undersides uniformly pale cupreous brown, wings sparsely covered with 



short, very slender, laxly disposed, hair-like scales; cilise long, dense; 



expanse of wings \^i\i of an inch. Habitat, — 'Calcutta. Type in 



collection of F. Moore.-"
