hunter: I'HE C0CCID.-1-: OK KANSAS. 5 



Scale of male. Elongate, broad and roundly convex anteriorly 

 and flattened posteriorly. The outline of margin of scale is egg- 

 shaped, broad end at anterior margin, exuviae covered with white 

 secretion, nipple and ring fairly distinct. When rubbed rather 

 large orange colored exuviae appear. Exuviae situated between 

 the highest point and anterior margin, sometimes on anterior mar- 

 gin. Length i mm., width about 'o mm. 



Female. Body circular, lemon yellow with man}' irregular deep 

 orange spots, the greater number along the caudal margin of the 

 penultimate segment. One pair of lobes notched on lateral mar- 

 gin, some specimens show lobes one entire the other notched. 

 Approach each other at distal extremity, well chitinized, especially 

 so along mesal margin near base. Two pairs of incisions with 

 chitinized processes. 



Plates forked, two caudad of each incision. One spine on 

 median lobe, a pair laterad of each incision, and another pair about 

 same distance laterad of second pair, as exists between first and 

 second pair of spines, the third pair of spines are not as near to 

 each other as the spines of the other pairs are. Five groups of 

 ventral glands, numbers shown on figure ii. Nine mounts of 

 females studied and many scales. 



A further discussion upon this variety will be given subsequently. 

 A comparison between a good series of the Carya iiva- with a series 

 from viii's Sign, is desired. The exact status of tliis variety ma\' 

 then be better set forth.

Since original description is not at hand for comparison I will add 

 the following notes: 



Scales rather evenly distributed over the branches of the tree. 

 Scales slightly raised in center, depressed around margin. Color 

 dirty gray, yellowish on top caused by exuviae showing through, 

 oval, 2 mm. by i}-2 mm. Exuviae laterad, covered by white se- 

 cretion, when rubbed orange colored exuviae appear; ventral 

 scale white, very delicate. 



Scale of male. Elongate oval, sides almost parallel. About 

 i^ mm. in length. Darker than female. Exuviae laterad, lemon 

 yellow when whitish secretion is removed. The scale is slight]\- 

 raised along its greater median line, depressed at margin. 



Female. Oval, lemon yellow. One pair lobes, median, show- 

 ing slight notch on distal margin and faint notches may appear on 

 lateral margin. Chitine appears to extend ceplialad from base of 

 lobes, mesal margins show chitinous processes.
