 Sta., Dept. Flant Path, and Ent. Bui. 9, pp. 15, pis. 2. fig. I). — Eight species 

 are considered. 



Report on the sugar cane borer in the Moluccas, F. Muir (Hawaii. Plaiit- 

 <rs' M(,., 28 {1909), Xo. 9, pii. 363-371. fig. /).— An account of a visit to the 

 Moluccas and the Teniuiber Islands in search of parasites of the sugar-cane 

 borer (SpJicnopJiorus obscurus). 



In the Tenimber Islands the borer was found to be very numerous and to 

 cause much damage to the sugar cane and various palms, but in Amboina it was 

 not common, its numbers being kept down by several factors, notably 2 pre- 

 daceous beetles, a histerid and an elaterid, and a tachinid. The histerid 

 is said to lay single eggs in the vicinity of the borer larva, and when food is 

 short will feed upon young leaf hoppers and other insects. The elaterid in 

 the larval stages feeds upon the borer larva and pupa, is hardy, and can stand 

 long fasts. The value of the tachinid as a death factor varies, according to 

 the condition of the sago palms, from 25 to 90 per cent. 



The borer was found in the Ceram sago palms but not in any great numbers. 

 The conditions were about the same as in Amboina, the 2 beetle predators being 

 rather rare, the tachinid fly fairly common. Out of 537 cocoons examined, .313 

 were attacked by the fly. In spots where no cutting or clearing had taken 

 place the borer was very scare and the percentage of cocoons attacked rose to 

 nearly 90 iier cent. 



In Amboina, Perkinsiella vastatri.r and a new species of leaf hopper were 

 found, the former also occurring in the sugar cane in Ceram. As in Java 

 and elsewhere, egg parasites appear to be an important factor in keeping these 

 pe^s in check. 



Combating Pissodes notatus, Eckstein (Ztschr. Forst. u. Jagdw., 1,1 

 (1909), No. ,}. pp. 209-232). ^his is a report of investigations of the biology 

 and methods of control of this pest. 



European bark beetles and their coleopterous and hymenopterous enemies,

 pp. 11,0, 11,1). — Host and enemy lists are given. 



A further note on the Chilgoza bark-boring beetles of Zhob, E. P. Steb- 

 BiNG (Indian Forest Rec., 1 (1908), No. 3, pp. 21,5-251).— This paper discusses 

 the steps taken by officers in charge of the Chilgoza forests of Zhob and Takht-i- 

 Sulenian, in combiitiug the scolytid beetles Polygraphus trcnchi, Phlwosinus sp., 

 and Pityogenes voniferw.
