the old adult females, but varying according to age; 

 the cephalic area is generally strongly and broadly 

 depressed. Colour varying from dull reddish-crimson 

 to rich dark crimson ; cephalic area and the margins of 

 the abdominal area often fuscous with darker wavy 

 lines ; dorsal area with transverse, interrupted, ivory- 

 white bands, which coalesce at the median line and 

 sometimes extend almost to the margin at the sides, 

 but they usually terminate before reaching the sub- 

 dorsal area and reappear again towards the margin in 

 broken lines and blotches ; there is also a conspicuous, 

 transverse, interrupted band of white crossing the 

 thoracic area, which widens towards the margin ; and 

 occasionally there is another very short band in front 

 of it ; all the white markings are strongly interrupted 

 by black or crimson-black marks and punctures. As 

 the insect advances to maturity the white bands 

 darken and gradually become fuscous, eventually dis- 

 appearing entirely. This is the Lecanium (Coccus) 

 fiixnnn of Grmelin. 



J3. Form resembling o, or broadly ovate and rather 

 flattened (fig. 2&). Colour dark crimson-black or 

 dark castaiieous, paler towards the sides ; dorsum with 

 a narrow, longitudinal, suffused band of yellow, and 

 there are from two to four short, broad, transverse 

 bands of the same colour at the margins. This variety 

 is by no means common. 



y. (Fig. 2 a.) Form resembling old adults, but 

 sometimes more attenuated behind. Colour rich dark 

 crimson with numerous transparent spots or freckles ; 

 dorsal area fuscous or ochreous, gradually merging 

 into the crimson. A form freely met with. 



S. Central area entirely pale dusky yellow to fuscous, 

 margins reddish or dull crimson-red, or entirely 

 fuscous. This form is common, and the pale colour 

 is undoubtedly due to the attacks of internal para- 

 sites.
