black head, thorax and thoracic lobes with three broad dark brown 
marks on each abdominal edge, a black mark over each honey-tube, 
and a dark patch on the last abdominal ring; the cornicles are black, 
legs yellow, with black knees and tarsi. These winged females occur 
at all times ot the year, even in mid- winter, on half evergreen roses. 
In the autumn a male appears now and again, and even in summer, 
but its exact appearance has not been described. The oviparous 
female is apterous and ferruginous-red with dark olive or black 
coloured legs. The eggs are at first yellow, but gradually become 
black ; they are glued to the base of buds and on to the shoots. 
The variety of this aphis, described by Buckton as var. glaucci , 
has the following characters : the winged female is bright green, the 
thorax with dark olive green markings, abdomen with four large dark 
spots on each side; honey-tubes dark; legs green. The apterous 
vivipaious female is oval and light green, covered with a mealy 
coating, and with two dark spots on the thorax. In the pupae the 
wing-cases are dark olive. These aphides occur both on the shoots 
and on the leaves, all stages occurring at once. 
Numerous parasites prey upon the Bose Aphis, especially Chalci- 
•iidte. These parasites deposit their eggs inside the bodies of the 
aphides, and the larvae devour the internal organs of the aphides, 
leaving the dry brown skins behind, from which the Chalcids 
have escaped. Lady-bird larvae and the adult Lady-birds also feed 
upon these pests, as well as the larvae of the Lacewiim Flies 
( Chrysopidse ). 
Treatment for Bose Aphis. 
The best wash lor Bose Aphis is soft soap and quassia alone ; 
paraffin is not well to use, as it checks the growth of the roses. 
In winter, spraying with caustic alkali wash would do some good 
III checking the pest. Spraying with quassia and soft soap has to be 
done repeatedly, for even if only a few are left they are enough to 
cover the bushes again in a week or so.
