106 THE CANADIAN ENTOMOLOGIST. 



Hah. — ^On bark of p;eony from Japan, quarantined by Mr. Craw, at 

 San Francisco. The pi^ony bark, boiled in caustic soda, gives a very 

 fane crimson or madder colour. Also on Camellia Japonica, in California. 

 (Dept. Agric, Div. Ent., 376*^.) The scales on Camellia were lighter 

 than usual. 



Diaspis celtidis, n. sp. — $ . Scale dark gray, exactly like the bark 

 on which it rests, fairly convex, first skin visible, brown or ferruginous, 

 placed near the margin. Greatest diameter of scale about i millim. 



$ . No circumgenital glands, even in a female full of young. Two 

 pairs of brown lobes; median lobes rather large, upright, separated by a 

 fair interval, in which is a pointed, squame extending very slightly be- 

 yond their tips ; second lobes separated from the median by a similar 

 interval ; median lobes rounded at the end, deeply and squarely notched 

 on the outer side ; second lobes bluntly pointed, deeply notched on the 

 outer side, the portion beyond the notch forming a pointed lobule, the 

 whole lobe resembling somewhat a lower molar tooth of Sorex. Beneath 

 each lobe is a pair of small pyriform brown glands ; some distance be- 

 yond the second lobe is another pair of these glands, forming a brown 

 patch, but without any lobe, and supporting a rather large spine. Dorsal 

 glands i&w in number. Anal orifice small, a good distance from hind end. 



^ . Scale of the usual Diaspis form, but short and broad, hardly 

 more than twice as long as wide, dull gray, not in the least carinate ; 

 exuvia placed longitudinally at one end, large, not far from half the 

 lengih of the scale, thick, dark brown, with small transverse ridges, and a 

 light brown margin and central longitudinal ridge Sometimes the whole 

 exuvia is light brown. 



Hab. — On Celtis, San Antonio, Texas, June 2^, 1898. (C. H. T. 

 Townseiid.) Somewhat allied to D. baccharidis, but difi'ers by the 

 formation of the lobes and the absence of circumgenital glands. On the 

 Celtis, at San Antonio, Prof. Townsend found also a variety of Pulvi- 

 naria innumerabilis (Rathv.). 



Diaspis auraiiticolor, n. sp. — -9- Scale circular or suboval, diam. 

 not much over i millim., only slightly convex, white, but covered with 

 a gray film of the epidermis of the plant. Exuviae lateral, bright lemon- 

 yellow, first skin exposed. Removed from the bark, the scales leave a 

 white mark. 



$ . Bright orange ; light yellowish after loss of contents, the orange 

 colour being contained in oil like globules, not altered by caustic alkali,
