 S. & A. ; Phobetron pitkecium, S. & A. (hag moth) ; the grasshoppers and 

 locusts, Schistocerca alutacea, Thunb., S. serialis, Thunb., and 

 Dictyophorus reticulatus, Thunb . ; the katydids, Cryptophyllus concavus 

 and Microcentrum retinerve ; Oncometopia undata, F. (orange Jassid) ! 

 Trirhabda brevicoUis, Lee. (prickly-ash beetle), the adults of which 

 sometimes defoliate citrus trees ; Aphis yossypii, Glov. (melon aphis) ; 

 and Diabrotica vittata (striped cucumber-beetle). 



Trees which serve as alternative host-plants of citrus insect pests, 

 and which, for this reason, should not be allowed to grow near citrus 

 groves are : — China-berry, prickly ash, privet, and wild olive {Osman- 

 thus americanus) (which particularly harbours whiteflies), camphor, 

 croton, oleander and rose. 



Sherriffs (W. R.). Spiders on Tea Bushes. — Planters' Chronicle, 

 Bangalore, xiii, no. 28, 13th July 1918, pp. 465-466. 



Damage to tea bushes is reported from Madras due to the presence 

 of a spider, Stegodyphus sarasinorum, Karsch, that builds its large 

 colonial webs round the ends of the branches of various bushes, such 

 as Opuntia on the plains, and barberry and tea on the hills. Loss 

 to tea-growers results from the webs surrounding the growing points 

 so closely that the development of the buds is arrested. Since the 

 colonies are conspicuous and their growth slow, any serious loss 

 would be the result of sheer neglect.

 Season 1917. — Qtrly. Jl. Scient. Dept. Ind. Tea Assoc, Calcutta,

During 1917 the most injurious pests of tea were : — Helopeltis 

 theivora, Waterh. (tea mosquito), universally distributed and occurring 

 from May to November ; Empoasca flavescens,¥ . (green fly), prevalent 

 in most districts in May and June ; Tetranychus bioculatus, W.-M. 

 (red spider) . in evidence in many districts and reaching a maximum 

 in April and May, being effectively controlled in some districts by 

 coating the leaves with a mixture of lime or sulphur with cowdung 

 and mud, or with a mixture of the last two only ; Heterusia magnijica, 

 Butl. (red slug), occurring only in small numbers throughout the 

 season ; Biston suppressarius, Gn., much less troublesome than 

 formerly, the three broods of caterpillars occurring in May, July 

 and September-October ; Clania spp. (bag-worms), causing only 

 shght damage ; Physothrips setiventris, Bagn. (common thrips), 

 Haplothrips tenuipennis, Bagn. (black thrips), and a new unidentified 

 species from Upper Assam that confines its attacks to the unopened 

 and opening buds ; Thosea spp. (nettle grubs), in evidence during two 

 periods. January to February and June to July, chiefly on unpruned 

 or hghtly pruned bushes. 



Other minor pests were : — Andraca bipunctata, Wlk. (bunch cater- 

 pillar) ; Agriophora rhombota, Meyr. (sandwich caterpillar) ; Acantho-
