apparatus. In the State of Johore, the total number of swarms 

 destroyed was 330. The results of the year's work may be considered 

 as satisfactory, as in Selangor and the Negri Sembilan the locusts have 

 certainly been reduced in numbers and a beginning has been made 

 with their destruction in Johore. It would appear that on the whole 

 the number of locusts present in the entire Malay Peninsula has been 

 considerably reduced.

 August 1915, pp. 217-251. 



A grub boring in the heartwood of a branch of a sandal tree, was 

 found in November 1913, and the imago, which hatched out in May 

 1914, was identified by the Forest Research Institute, Dehra Dun, 

 as an unknown species of Lamiidae. According to Stebbing, the 

 borers attacking sandal are Zeuzera cqffeae, Sirex sp., and Stroniatium 

 sp. The last-named was afterwards thought to be a species of Coelos- 

 terna, but the description given corresponds with the appearance of 

 the Lamiid here reported.

 Forester, Allahabad, xli, no. 8, August 1915, pp. 294-299. 



During the compilation of Stebbing's " Indian Forest Insects of 

 Economic Importance, Coleoptera " [see this Review, Ser. A, iii, 

 p. 154] the investigations carried out with some species have supplied 

 further information necessitating some alterations. Corrections in 

 the nomenclature are here dealt with, especially as regards species of 

 considerable economic importance, which are beginning to appear in 

 departmental literature under incorrect specific names. The Cerani- 

 bycid, Tetropiiim oreinum, Gahan, has been wrongly recorded as 

 Trinojihylum cribratum, Bates. An examination of a long series of the 

 Scolytid, S2^haerotry2)es siwalikensis, Stebbing, has convinced the 

 author that S. assamensis is a spionym of that species. Xyleborus 

 bengalensis, Stebbing, is a synonym of X. semigranosus, Blandford. 

 Crossotarsus saunderbi. Chap., or possibly a local variety of it, is without 

 doubt the species referred to as Diajnis heritierae, Stebbing. From 

 material collected in 1906, 1909 and 1912, Col. Winn-Sampson described 

 two new species of Platypodinae, Diapus fpstivus and Diaqms minis. 

 Recent field-work shows that these two s]:)ecies are identical and that 

 the sexes in both cases have been wrongly interpreted ; the former 

 name has priority. 



Cockayne (A. H.). The subterranean grass-caterpillar. — Jl. Agric, 

 Wellington, N.Z.. xi. no. 1, 20th July 1915, pp. 13-17, 4 figs. 



Widespread damage to grass land is caused by subterranean grass- 

 caterpillars, the larvae of moths of the Hepialid genus Porina. 

 P. umbracuJata and P. cervinata are the two most destructive species and 

 have been present in enormous numbers in the Wellington district, 

 about 40 to the square yard having been counted. The larvae burrow 

 into the soil and remain during the day at a depth of 1 to 6 inches.
