Most of these bugs also attack Indigofera arrecta, as do the 

 Pentatomids Halyomorpha picus, Piezodorusrxbrofasciatus, Ensarcomns 

 guttiger and Tolutnnia immaculata. 



Sweet potatoes {Ipomom batatas) were attacked by the weevil 

 Cylas formicarius, the Cassids Aspidomorplia miliaris and A. micans, 

 and the P}Talid Tahidia aculealis. 



Other miscellaneous pests include : Plutella macidi'pennis on varieties 

 of Brassica olemcea ; Crocidolomia binotalis on Chinese cabbage ; the 

 Pentatomid bug Bagrada picta on knol-khol ; Docks oicurbitae on 

 Sechimn edide ; Dorylus orientalis on potato {Solamim tuberosum) ; 

 and a Cerambycid beetle, probably Batocera rubus, on the jak tree 

 {Artocarpus integrifolia).

 [Received, 7th October 1920.] 



Soap-resin- fish-oil emulsion has been applied to bushes, immediately 

 after pruning, over an experimental area of 161 1 acres, but has not 

 proved as efficacious in the control of Xyleborus fornicatus, Eich. 

 (shot-hole borer of tea) as was originally anticipated. 



An area of 24 acres has been interplanted with castor-oil plants to 

 test their value as trap-trees. The periodical removal of infested 

 branches is apparently an effective method of control, provided that it 

 is systematically carried out. The number of fresh estates declared 

 infested is 22.

The sweet potato weevil [Cylas formicarius] has only been found in 

 the four southernmost counties of Mississippi, and regulations have 

 been adopted to prevent its further spread. Remedial measures so 

 far carried out have been very successful, and if they continue under 

 similar conditions the State should be free from the weevil within 

 from one to two years. The Argentine ant [Iridonryrmex huinilis] 

 is spreading rapidly, but funds have not been sufficient for the under- 

 taking of systematic remedial measures. 



The cottony cushion scale [Icerya purchasi] attacks a great variety 

 ■of plants, and is established in about five counties.
