with the plates, but arise from the ventral surface of the body 

 cephalad of the plates and extend out under the plates caudad. 



On a pear tree brought from New Jersey. Location near Argen- 

 tine, Kans.* 

 Aspidiotus greenii Ckll | Plate VI, Fig, 24. 



In the old scales found at base of palm leaf the exuviae are nearly 

 black, scale grayish black. 



The plates found between the median lobes are in some cases 

 forked. There is also a variation of two in the number of toothed 

 plates. In some there are two more upon a side than in others. 

 The greatest number of toothed plates found on a side was six, 

 jsimple plates constant at four. Their relative position as well as 

 the number and position of the spines is best shown by the figure. 



Fifteen mounted females studied, and many scales. Found 

 massed at base of palm leaves and extending a short distance up 

 the leaf. 



On the palm, Howca bclinorcana, in green house. Lawrence, 



Kansas. 



Aspidiotus hederae Vail. var. nerii Bouche.:}; Plate VI, Figs. 26, 27; Plate 

 VII, F"igs. 28, 29. 



Scale of female and male agree with description. Position and 

 condition of first and second skin of female as described. 



Female, light yellow in color mottled with yellow. 



The anterior and posterior lateral glands agree with numbers 

 given, but in two specimens out of the twenty-five studied I find 

 in the one case a pair of glands forming an anterior group. In an- 

 other specimen I find an anterior group of two with one lying be- 

 tween this group and the right anterior lateral group. This I 

 have shown in the sketch. This group of glands, not spoken of by 

 Bouche or Comstock, is of interest. The plates and spines agree 

 satisfactorily with the description. The comparatively small num- 

 ber bearing this anterior group may be the reason why this group, 

 probably observed, f is not mentioned in the original descriptions. 



*l'his tree was bought three years aso, when two years old, from Parry's Pomona 

 Nursery, Parry, N. J.' It was placed at northwest corner of a young orchard. It has 

 been rooted up and burned. The writer visited this orchard on Dec. 10, 1898. and gave 

 the grounds a careful examination; two small colonies of about a dozen individuals 

 eacli were found on two trees adjacent to place where infested tree stood. These 

 liMve been cut away, and the owner, a progressive horticulturist, intends sub.1ecting 

 all the trees in that part of the orchard to a thorough treatment with whale oil soap 

 wash as an extra precaution. 



+ [ was unable to find reference in literature to median group '\n A»x}\A\otu% s. str. 

 I wrote Prof. Cockerel 1 concerning my observation and asked for reference to such a 

 group. He finds that Barlese examining .l.'*pi"rti>>f((.s htidnai \-Avlimon\\ in Italy found 

 one example with one gland representing the median group. Oockerell adds interest- 

 ingly: "-The appearance of a median gland thus Is probably an atavistic feature, as 

 the supposed anc&stors of ospidiofus s. str. (Di'«8p(S-like types) probably had the five 

 groups." . . _,.
