Two pairs of incisions, each bearing chitinous processes on 

 sides, processes nearly equal in size but rather wide apart. 



Plates inconspicuous, one or two caudad of second incision, 

 small. Spines prominent, one on lateral margin of median lobe, 

 two between first and second incisions upon what might be con- 

 sidered a depressed lobe. One spine laterad of second incision 

 and another spine half way between the fourth spine and a pair of 

 spines on the lateral margin. Another spine appears on lateral 

 margin near penultimate segment. (Not shown in figure.) 



Four groups ventral glands, caudo-laterals 4 to 5, cephalo 

 laterals 4 to 6. 



From many scales and mounted specimens.

Aspidiotus ulmi Johns. Plate III, Fig. 14. 



Found in two localities in the city of Lawrence upon catalpa, 

 massed upon the branch of the tree. In an entirely different lo- 

 cality upon Ulnuis ftilva. It seemed in each case to be of long 

 standing. Many old scales were found covered by the outer cork 

 layer. 



The scale of female agrees quite well with original description, 

 except that I would not call the scale ''quite convex;" slightly con- 

 vex suits here better. Male scale agrees with description. 



Mature female differs from original d'iscription and figure in hav- 

 ing two notches upon the mesal margin of the lobes. In some 

 specimens the proximal notch is faintly marked. The drawing 

 made from the type shows here a slight curve. 



The thickening of body wall as shown in original description is 

 quite characteristic of specimens examined. In an examination of 

 twenty mounted specimens no circumgenital glands were found.

 Figs. 15, 16. 



Abundant on the trunk from the ground up. When the tree is 

 wet the exposed ventral scales stand out almost like fine flakes of 

 snow. 



In the orange exuviae, and in the mode of congregating and shape of 

 scale, this insect favors ancyclus. The color of the scale is lighter and 

 the structure of the female precludes the possibility of its being 

 aiiixclus. The Putnam scale prefers the branches, this scale the 

 trunk. I have been unable to find a species described in the liter-
