undoubtedly also a parasite of Batrachedra amydraula. Meyr. the 



caterpillar causing the " hashaf " condition in dates. A number of 

 minor cotton pests also occur, including the stainer, Oxycarenus 

 hyalinipennis, Costa, though Dysdercus is conspicuous by its absence.

 Algiers. Attention is called to the danger of the spread of Icerya 

 pufchasi in Algeria. A decree has been passed by the Chamber of

Importation of Sugar-cane into British India by Sea.— Tw/). Agric.

Under the revised regulations the importation of sugar-cane into 

 British India from the Fiji Islands, New Guinea, Australia and the 

 Philippine Islands is entirely prohibited. From elsewhere it must 

 be accompanied by a certificate of inspection pronouncing it to be 

 free from cane-borers, scale-insects, Aleurodcs, and various diseases. 

 It must come from a crop that is free from mosaic disease, and Fiji 

 disease of sugar-cane must not occur in the country of origin. In the 

 case of plants intended for cultivation under the personal' supervision 

 of the Government sugar-cane expert, an official certificate is required 

 that the country of export is free from Fiji disease.

The chief feature of this number is the brief review of the principal 

 pests occurring duiing the winter of 1921-22 and the spring of 1922. 

 These include Blissus leucoptcrus, Say (chinch bug), which suffered 

 very little during the comparatively mild winter. Investigations 

 m Ohio indicate that this pest normally hibernates in woodlands, and 

 not in the weeds and grass along the fence rows as was formerly 

 supposed. Mayetiola destructor. Say (Hessian fly) has not been reported 

 as serious in any important wheat-growing centre. Toxoptera graminum. 

 Rond. (wheat aphis) has been practically absent from northern Texasi 

 the severe droughts of the preceding summer having prevented the 

 gro^^•th of self-sown wheat. There has, however, been an outbreak in 

 northern Oklahoma and eastern Kansas ; it appears, therefore, that these 

 outbreaks are not necessarily the result of the northern ' migration 

 of the Aphid from northern Texas. Eleodes opaca. Say (false wireworm) 

 has become seriously abundant and destructive in western Kansas 

 and Nebraska. The dry autumn and winter in many localities pre- 

 vented germination of the seed until the spring, aiid consequently 

 favoured the pest. The maize-borer discovered in Texas and northern 

 New Mexico last summer has now been determined as Diatraea lineolata. 

 Wlk. In part of Texas the infestation amounts to 50 per cent, of the 

 crop. Hylemyia cilicrura, Rond. (seed corn maggot) has been reported 

 from North Carolina, Alabama and Louisiana. Lycophotia margaritosa.
