marked incisions each side, varying little in size, each of 

 which is bordered by a definite pair of chitinous processes. 

 A forked plate and simple plate laterad of median lobe, one 

 to three simple plates between first and second incisions, and 

 one or more simple plates laterad of second incision. Median 

 glands are occasionally present but not exceeding three in 

 number. Cephalolateral glands, nine to fourteen; caudo- 

 lateral glands, six to nine. 



Habitat: Walnut, Jiiglans nigra, at Lawrence, Kan., 

 (Hunter.) 



ASPIDIOTUS SUBSIMILIS Ckll 



Cockorell, T. D. A., Am. Mag. Nat. Hist-, p. 1G8. Fob. 1890. 



Female anal segment with median lobes rather long, 

 rounding; rudiment of second lobe usually slightly doubly 

 concave; rudiment of third lobe co-extensive with lateral 

 margin. Median incision very shallow; second and third 

 incisions also shallow. Two small chitinous processes on 

 the base of median lobe; inner process of first incision much 

 elongated, enlarged at apex, club-shaped, outer chitinous 

 process shorter and only slightly enlarged; processes of second 

 incision about equal. A pair of spines from each second and 

 third lobes and a simple spine at about the middle of lateral 

 margin; probably also a pair of spines from median lobes. 

 Ventral grouped glands absent. Plates not detectable in the 

 six type specimens examined. 



Habitat: Cuantla, Mex. 



This appears to be a very distinct and peculiarly char- 

 acterized species, especially in the nature of the chitinous 

 processes.
