To l»e of much service the wash must l>e usetl when the insects 

 are in the larval or pupal stage. A hnik-out sliouUl l>e kept in the

 the winter ([uai-ters are discovere<l steps shoultl Ikj taken to destnty

 species passes the winter in the egg stage on the chrysanthemums, 

 the jtlants should he sprayed with jiaraffin emulsion as scM)n as the 

 young larvic are seen to apjtear. 



The Destruction of Ants. 



The foll(»wing infonnation was .sent to a corresjwndent of the 

 lioard of Agriculture at Kingston-on-Thames concerning the method 

 of destroying ants damaging gi~ass and clover. 



First find out the ants' nest. This may he under the gr«»und, in 

 which case it can t)nly be detected by following the ants and so 

 finding the i»]>ening in the soil down which they descend; nests may 

 al.s(t l>e formed un«ler dome-shai>ed masses of earth, etc., al«>ve gn»un<l 

 or they may l>e under stones and rotting wood, accoiiling to the 

 s|>ecies of ant concerned. 



Having located the nests, make a hole in each one al>out eight 

 inches in depth and then j)our into each hole from 1 to 2 uzs. 

 of bisulphide of carbon, according to the size of the nest, and fill 

 up the hole at once with earth. If the ground is regularly under- 

 mine<l with ants' nests an<l tunnels, treat the .soil with the same, 

 making holes every three feet apart, and )M)ur into ench hole '1 ozs. of 

 the bisul])hide f»f carlMUi. This is as a rule not neces.sarv for ants, the 

 nests <»nly needing treatment. Evening is the W'st time to attack 

 them. Care must l»e taken not to ])iit a light nenr the bisulphide of 

 carlnm or to let it come in contact with hot metal, as it is highly 

 inflammable. This is the oidy plan by which ants can l»e cleare<l 

 out of the soil and has so far always met with success. 



There are veiy few jwinisitic enemies «if ants. A genus of 

 Ichneumon flies, EUimnttsonto, is one of the few parasites that attack 

 them, whilst a brilliant Chnlcid, Eitcharin mtfrmfrifr, is known to prey 

 on the large Australian Myrmfcin. A small fly, Phora /onitimnnn, 

 Verrall, lavs its eggs on ants, inside which the larviu live Ants
