Vol. II., Part I., p. 61-8. From this I will «|uote the suiiiinary, which 

 will be suffifieut here : 



" The egg is lai(,l in a small hole in the surface of the ground. On 

 hatching, the grub burrows into the soil and lives on the well-rotted 

 roots and other vegetable matter contained in it. Having attained a 

 size of about £ of an inch in length, it forms for itself a chamber in 

 the earth, about 2 iuches below the surface, in which it undergoes its 

 metamorphosis. The perfect insect burrows its Avay out of the earth 

 at night and flies, probably the next day, in search of food. Having 

 found a tree on which it can live, it stays on it while there is any leaf 

 to eat, the females leaving the food plant from time to time to deposit 

 their eggs in the ground. 



" The results of digging showed that the grubs were most fre(juent 

 in the cleanest land. I dug in grass and weeds in many parts of the 

 estate, but could not find one. The same results followed digging in 

 scrub and lalamj land, and also luider the hedges ... In the 

 clear land, in one place, as many as six grubs were found within an 

 area of less than one square yard ; but, on an average, there are not more 

 than one or two per square yard. Of course, the younger ones being 

 vei-y small undoubtedly escape observation when turning over the 

 soil. At one per square yard we get 4,840 per acre, which is a suffi- 

 cientlv large total to account for a verv extensive destruction of foliage." 



Takmg into account the life history of the insect, there appears to be 

 only one period of its life when it is [)ossible to attempt tj destroy it — 

 and that is when it has attained maturity. Then it might be collected 

 by hand picking or killed by poisoning its food supply with one of the 

 arsenical powders applied as previously mentioned. Mr. E. Lauder 

 Watson informs me that he has nearly exterminated it l)y handq)icking. 

 The same method was also reported by the late Sir Greame Elphin- 

 sstone to be effective in ridding the Liberian coffee on Gapis Estate of 

 the same pest. 



DIE INLANDSTAMME DEK MALAYISCHKN

iJY Dk. JIUDOLF MARTIN. 



T"N this work — which covers two volumes and is extremely well 

 printed and illustrated — Dr. Martin discusses the data that he 

 has obtained, either personally or through the reports of other obser- 

 vers, regarding the wild tribes of the Malay Peninsula. He does not 

 do more than touch upon linguistic questions, but, except in this 

 important branch of research, his work is very thorough, and is only 

 inconclusive Ijecause the data that we ]>ossess are insufficient to lead 

 to any very positive results.
