hunter: the coccm.i': oi' Kansas. 71 



On walnut, the same species was found, but the scale is uni- 

 forml)' 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 Ji/glans nigra, Universit}' Campus, April, "98. 



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, 



Lecanium armeniacum Craw Plate XV, Fig 4. 



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 quoted as 

 associating that insect with juglandis, a 7-jointed species. There 

 being no descriptions, specimens /// situ, 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, /a. 



Antennae 6 and 7 jointed, the basal joint quite 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 chaetotaxy and relative dimensions 

 shown in figures. 



Legs are slender and might be characterized by the marked 

 constriction at the joints. There is an exception to this, however, 

 in the case of the trochanter and femur. Here the segments are 

 simply marked off by a straight line, no noticeable indentation 

 being apparent on the margins. Tarsus bears two long slender 

 knobbed digitules, claw bears two much shorter and 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
