On walnut, the same species was found, but the scale is uni- 
formly smaller and the size of .segments of leg and antennae cor- 
respondingly less. Long. 6-7, lat. 4 5, alt. 3-4, fx. A compari- 
son of figure 2 with figure 3 will show differences in size of the 
antennae and legs of the walnut and elm scales. 
Habitat on /ug/a /is ///g/n, University Campus, Ajiril, 'g8. 
From the relative sizes can it be said that elm is the better adapted 
host? 
Professor Cockerell writes that he has received specimens of 
this scale from Mr. G. B. King and several other correspondents 
but the material was in unfit condition for description,

Comparison of the infested twigs with photograph upon title 
page of bulletin No. 83 Cornell University by M. V. Slingerland, 
suggests a possibility of this being the same species. Later, 
however, in the description, Professor Cockerell is-tjuoted as 
associating that insect with Jugla/idis, a 7-jointed species. There 
being no descriptions, specimens in si/n, or slide specimens at 
hand the following notes are offered. 
Scale of female, crowded closely upon twigs of plum sometimes 2 
and 3, one upon another. Color of scale pale brown; some of scales 
full and show no foldings, others show a row of pits on each 
side of longitudinal median line and sides plicate. Some scales 
have retained their form while others are much shriveled up. The 
shape of scales, hemispheroidal with sides somewhat depressed. 
Long. 4, lat. 3, alt. 2.5, /*. 
Antennae 6 and 7 jointed, the basal joint (piite stout and globular, 
the first and second segments bear unusually long hairs, the third 
segment (when 7 jointed) bears one, the fourth again bears two 
unusually long hairs. Further chaAotaxy and relative dimensions 
shown in figures. 
Legs are slender and might be characterized by the marked 
constriction at the joints. There is an e.xception to this, however; 
in the case of the trochanter and femur. Here the segments are 
simply marked olf by a straight line, no noticeable indentation 
being apparent on the margins. Tarsus bears two long slender 
knobbed digitules, claw bears two much shorter ami stouter dig- 
tules. 
Habitat, on plum twigs. This insect was found by the writer 
among the collections and bore the label ‘‘Scale bugs on plum, 
Kansas.’’ Reference to the lot number showed that these scales
