In cases where the trees attacked are accessible to applications of a 
remedy, I should say therefore that a strong solution of common soap, 
applied by a syringe in dry weather, might be found to be the best. 
Doubtless, in large plantations of tall trees say of many acres, especially if 
the insect is well established, it would be difficult to apply any remedy at 
all. 
General Description of the Insect. 
Suggested name—Kermaphis pini, Koch, var. levis. 
Anisophleba pini, Koch. 
Plate VIL., figs. 1-11. 
Occurs in colonies surrounded by masses of white cottony secretion, 
clothing the twigs of pine trees. This secretion contains great numbers of 
apterous oviparous females, with ova and young xis 
Eggs oval, yellow or brown, length about jj inch, not pedunculated 
(fig. 1). 
Young larva just hatched, yellow, elongated oval, flattish: body seg- 
mented, the segments diminishing to the anal extremity (fig. 2): eyes brown, 
conspicuous. Antenna (fig. 8) of three joints, each numerously ringed, the 
third joint being longer than the other two together; foot normal of 
Aphidide : rostrum not longer than the body; a few short spines on the 
segments. The larva is somewhat active. 
Apterous oviparous female dark brown in colour, semiglobular, convex 
above, flat beneath, resembling somewhat the Coccid insect Rhtzococcus 
(fig. 5). Length from 4, to 4; inch, breadth and height rather less. Body 
segmented, but without spots on the dorsum and sides. Antenna (fig. 7) 
very small, of three (?) atrophied joints, the last bearing some hairs. Foot 
(fig. 9) normal of Aphididm. Abdomen ending in four minute but some- 
what strong spines (fig. 8). Cornicles (honey tubes), none, unless the 
spines just mentioned may answer to them. When the insect has been 
macerated in potash and the interior substance expelled, the skin is found 
to be covered with numerous small circular orifices arranged in groups, - 
whence is secreted the white cotton. 
I am not acquainted as yet with the male, nor with the winged state of 
the female. According to Buckton (British Aphides, vol. iv., p. 41), the 
winged forms of Chermes pini are also not exactly known 
This insect differs from C. (Anisophleba) pini in the iene of peduncles 
in the eggs, and from both that and C. corticalis in the absence of spots on 
the dorsum and sides, and in the form of the female antenna. I give for 
comparison (fig. 11) a copy of Buckton's figure of the antenna of C. corticalis. 
Probably also the spines at the extremity of the abdomen. may be distinc- 
tive.
