(Plate XIX., fig. 2.) 



^. Gall forming a rounded or oblong swelling on the branch, out 

 of the centre of which springs up a tubular gall from 2 to 4 lines 

 in height above the excrescence on the branchy 4 lines in diameter 

 and perfectly flat on the truncated apex, with the exception of tlie 

 small cone-shaped projection in the centre, encircling the minute 

 apical orifice. The walls of the galls are stout and solid, containing 

 a chamber rounded at the base and pointed towards the apex; 

 each of these galls is distinct from the large swelling upon the 

 branch from which they project, and can be detached without 

 breaking. 



5. Coccid dull 3"ellow, 4 lines in length, broad and round at 

 apex, central lobe with two ver}^ small antennae and short fore- 

 legs, the second pair rather large, with the hind pair largest, the 

 first joint swollen and almost globular; the last thoracic segment 

 broad, the first four abdominal ones regular, and tapering sharply 

 to the tip, the anal segment, bearing the anal appendages, rounded. 

 Dorsal view, head, and thoracic segments covered with very fine 

 scattered tubercles, but bearing no regular spines; first abdominal 

 segment with short irregular black spines along the apical margin, 

 on the second segment increasing in numbers and regularity until 

 on the last two forming a close regular ridge of stout black spines; 

 anal appendages black, very short, broad at the base, conical and 

 almost in contact at the base until near the apex, opening into a 

 V-shaped angle; the whole coccid lightly covered with hairs, 

 thickest towards the extremity of the abdomen. 



^. Gall and coccid unknown. 



Hab. — Wallsend, near Newcastle. On a small rough-barked
