'persicae, Phylloxera corticalis, and the Psyllids, Rhinocola eucalypti and 

 R. diantlii, have been recorded. No changes have been made in 

 connection with plant and fruit import regulations. An area in the 

 midlands of the Cape Province was overrun by migratory locusts in 

 the spring and summer of 1913-14. The species concerned was 

 probably Locusla pardalina. Hatching began early in October and 

 continued for several weeks. In addition to such control measures as 

 spraying and the use of poisoned bait, an effort was made to utilise 

 Coccobacillus acridiorum . The success of this measure was not apparent . 

 Winged locusts were observed in November and migrated into the 

 Transvaal, Basutoland and Natal. A second generation appeared early 

 in February in the Hofmeyr, Middelburg, Steynsburg and Molteno 

 districts. The South African Central Locust Bureau has received 

 reports from the different territories as to the presence or absence of 

 locusts in 1913-14. Basutoland reported the entrance of a swarm, 

 and mentioned that the insects were collected by natives at night and 

 the extermination of the swarm is attributed to this action. Winged 

 swarms of Schistocerca peregrina were reported from German East 

 Africa in November and December 1913. The flight was from the 

 mountains towards the plains. In February 1914 a new breeding 

 place was reported in the districts of Kondoa-Irangi and Dodoma. 



Progress has been made in the investigations of Busseola (Sesamia) 

 fusca (maize stalk borer), the beetles, Heteronychus arator and Phora- 

 cantha recurva, and a tree cricket. Measures for the suppression of 

 the Argentine ant, the mealy-bug and the house-fly have received 

 attention. Muscidifurax vorax, a parasite of the house-fly, has been 

 discovered. Living material of Coccus indicus, which destroys Opuntia 

 monocantJia, has been received,

The paper gives an account of the sub-family Lecaniinae, which 

 is represented by many native species and by most of the cosmopolitan 

 genera which have been accidentally introduced with their food-plants 

 and are now well estabUshed in orchards and gardens. Ceronema 

 hanksiae occurs on the leaves of Banksia serrata. C. caudata has been 

 found on the foliage of Eucalyptus robusta and C. dryandrae on Dryandra 

 jlornhunda and D. nivea. Pulvinaria contexta and P. darwiniensis feed 

 on Bossiaea sp. and Caladium sp. respectively. P.floccifera occurs on 

 many garden shrubs, such as Camellia, Euonymus, Brassia, Phaius, 

 etc. ; it is a common hothouse scale in England and France, appearing 

 on the underside of the leaves. P. maskelli is common on Atriplex sp. 

 and Rhagodia sp., fodder plants widely gi'own in Australia. P. nuytsiae 

 and P. greeni have been found on Nuytsia florabunda and Myoponmi 

 deserti respectively. P. tecta is a common pest on Kunzea capitata and 

 Daviesia sp. P. theae has been found on the leaves of Thea viridis. 

 Ceroplastes ceriferus (Indian wax scale), introduced with ornamental 

 shrubs, has spread from garden plants into orchard and waste land ; 

 Busaria spinifero. and citrus trees are generally attacked. C. rubens 

 (red wax scale) is common on tea, mango, palms, fig, ivj, etc., and 

 has been recorded on plum, pear and orange.
