the eggs of L. serricorne. During the six- week voyage to Europe there 

 is no danger of clean bales being damaged by infested ones stowed 

 alongside them. Nor are clean bales infested by means of adult 

 beetles flying about the hold, as they are unable to penetrate the 

 matting with which the bales are covered.

 beetle and L. laeve, Illig., infesting cigars in Holland by J. C. Konings- 

 berger, J. Ritsema Bos and L. P. De Bussy [see this Review, Ser, A,

According to Koningsberger and follownng him, Sorauer, Plagiolepis 

 longipes (gramangant) is a species that carries off tobacco seed. It is 

 here pointed out that P. longipes was not represented by even a single 

 specimen in two large batches of ants collected on various tobacco 

 estates at Klaten, Java. P. longipes is a Camponotine with habits 

 very dissimilar to those of the true robber-ants, which all belong to 

 the Myrmicinae. In the first batch, which apparently included all 

 ants found on tobacco seed-beds specially prepared as traps, ants 

 other than seed-robbers were represented. The second batch was 

 collected from ordinary seed-beds and corresponds to normal conditions. 

 Both contained numerous individuals of Solenopsis geminaia, F. 

 (fire ant), which is probably the species concerned, at least in the 

 Klaten district and probably in other parts of Java too. It also 

 carries away the seeds of Ocimum hasilicum. A description is given 

 of all its stages together with a brief note on its life-history. As it 

 is a ground inhabiting species, remedial measures are not easily applied. 

 In the Klaten district the seed-beds are isolated by channels of running 

 water. If this method cannot be used, it is advisable to spray the beds 

 with petroleum-soap emulsion.

 Rice Plants.] — Teysniannia, Batavia, v, 1918, pp. 270-275, 1 plate. 



At the end of March 1918 caterpillars and pupae of Cirphis unipuncta. 

 Haw., were received from the Buitenzorg district where this species 

 was injuring rice. Specimens of this moth that were obtained in the 

 past from Java were formerly recorded under the name Leiimnia 

 extranea, Gn., which is a synonym of this species. The caterpillars 

 are found in paddy-fields from which the water has been drained, but 

 they are more abundant in fields ready for cutting and somewhat 

 dry and almost absent in fields where the ground is sodden. Feeding 

 is confined to the leaves, but this injmy is unimportant. The real 

 damage, estimated at 18 per cent, of the crop, is due to the caterpillars' 

 habit of cutting ofE portions of the ripe or nearly ripe ears, and in some 

 cases the ground is covered with these. Effective remedial measures 

 include the wetting of fields nearly ready for the harvest either by 

 flooding once or twice or by preventing the out-flow of rain-water.
