Old adult female after death (figs. 2-4) dusky 

 cliestnut-brown, more or less shining. Form spheroid 

 or oblate-spheroid, generally much the highest and 

 evenly rounded in front, the body sloping suddenly 

 from a little behind the middle to the anal extremity, 

 from which radiate four distinct sulcations (fig. 3), 

 usually with deep punctures and wrinkles, but both 

 are sometimes wanting ; upper sulcations often 

 irregular and ill-defined (fig. 3 a) ; there is also a 

 well-defined groove just within the margin, which 

 deeply and suddenly constricts the body immediately 

 above its attachment to the branch, a character most 

 strongly marked at the sides and posterior extremity. 

 Examples on slender twigs, more especially those of 

 the elm, are almost invariably spheroid, with little or 

 no attenuation behind. Antennae (figs. 5-5 //) usually 

 of seven joints, but examples occur with both six and 

 eight joints ; fig. 5 a may be taken as a typical example, 

 in which the third and fourth joints are the longest 

 and almost equal, the articulation being in all cases 

 very faint, and when absent the two joints apparently 

 unite and form one long joint, the antennas then 

 possessing but six joints. Terminal joint with three 

 or four short spine-like curved hairs and several simple 

 hairs. The antenna in fig. 56 is from a parasitised 

 female, and shows a remarkable division of the fourth 

 joint, which may have been produced by the parasites. 

 Legs short and stout, and apparently partly atrophied; 

 the anterior pair (fig. 6) bent inwards at the articula- 

 tions; tibio-tarsal joint usually broader than the centre
