its recent spread into Egypt, Brazil and Mexico and on the United 

 States border is described. 



In East Africa the German Goveniment had only one method of 

 dealing with the pest. The Cotton Ordinance of 30th July 1910 

 required complete clearing of the fields after harvesting and the 

 burning of all parts of the cotton plants above ground. No measures 

 were taken as regards the collection of infested bolls or the disinfection 

 of seed. 



Most of the information given relating to remedial measures is 

 taken from the reports and papers on work done in Egypt in recent 

 years [R.A.E.. A, vi, 42; ix, 316; etc.].

A diseased condition of the foliage of vines, first noticed in July 

 1918 at Bengasi, is now believed to be due to infestation by a Jassid, 

 here described by E. de Bergevin as a new species, Chlorita lybica. 



A thrips, Dictyothrips zanonianus, found on the vine at Bengasi in 

 1917, has been recorded by Del Guercio.

During 1921 Cruciferous plants in general and cabbages in particular 

 were injured by a Lepidopteron. The adults oviposit on the basal 

 leaves and the larvae bore superficially into the stem, the tissues 

 being thus exposed to other insects, fungi and bacteria, so that the 

 plant ultimately rots.

 October 1921, pp. 226-230. [Received 7th March 1922.] 



The species dealt with include Ernestia johnsoni, sp. n., the male 

 of which is described from Massachusetts. It has been bred from 

 Hyphantria cunea, Drury, but should not be confused with E. anipelus, 

 Wlk., which is a major parasite of Hyphantria.

The Indian house-sparrow {Passer domesticus indicus) appears to be 

 a pest wherever it occurs. The young nestlings are fed largelj^ on 

 insects, chiefly caterpillars, but by the time they are about three weeks 

 old their diet is made up almost entirely of grain. The nestlings are 

 attacked by the blood-sucking larvae of a fly, Passeromyia heterochaeta.
