72 KANSAS UNIVERSITY QUARTERLV. 



were taken by Prof. V. L. Kellogg in 1891. The date of collection 

 was not given but upon twigs there remained some leaves and 

 blossoms so that the time of the year can be satisfactorily deter- 

 mined. 



A comparison with descriptions of /.. /v/t,v.\v//// Sig.''' shows 

 not "rugose" but plicate, not "hills" but ridges and furrows upon 

 the sides. The plum scales are light brown. Antennae 6 and 7 

 jointed, never "eight": in view of obscurity of segmentation, it is 

 interesting to note that the plum scale agrees with n/gosii/n in that 



3 exceeds part distad of 3, if 3 + 4 are one segment as in plate, figure 



4 (/, but if they are as drawn in same plate, figure 4 /', joint 3 is less 

 than all distad. Size uniformly smaller than n/i^osin/i, plum scale 

 elongate, riii:;osiii/i circular. Groove in anterior tarsus not shown; 

 posterior tarsus not wider than til^ia: chcttotaxy not similar. 



With the Queenston scale:")' — "legs well developed," trochanter 

 has "one" hair, coxa bears not "one" but two long and two short 

 hairs. Length of femur, tibia and tarsus within possible bounds, 

 but digitules of claw not "long" Init short and stout extending but 

 little beyond claw. 



No further literature being at hand for comparative study 

 I sent this scale with my notes to Professor Cockerell. He says. 

 "This scale has much in common with .Z. arnicniaiiiiii, yet seems 

 not quite the same. I wish we knew the sub- adult (living) female 

 and the newly hatched larva." Professor Cockerell kindly sent me 

 specimens of anneniacum. A comparison shows, legs similar; 

 antennae agree with seven segmented specimens except that 5th 

 joint in armcniacum is shorter than in plum insect. 



Tlie greatest difference appears to be in the scale itself. When 

 bleaching, it colors the fluid a yellowish ochre; the plum scale gives 

 off brownish coloring. Scale of ariiwiiiacum is not plicate and 

 shows no longitudinal median raised smooth ridge; this insect,, <//- 

 meiiiacuin, is more hemispheroidal with side quite full; plum scale 

 more elongate and flattened. 



Professor Cockerell suggested that Mr. Theo. Pergande be con- 

 sulted since he has been working upon these fruit tree Lecaniums. 



Accordingly I have received the following from Mr. Pergande 

 through Dr. Howard: 



" I have examined and compared the specimens sent with 

 mounted and dry material of Lrcaniinii aniicniacinn in our collection, 

 and have come to the conclusion tliat the plum scale from Kansas
