A NEW ASPIDIOTUS FROM PINUS SYLVESTRIS. 
T. D. A. COCKERELI . 
Aspidiotus ( Diaspidiotus) glanduliferus n. sp. Female scale 
large, 2 mm. diameter, slightly convex, blackish (the color of 
the bark), with large subcentral to sublateral orange-ferruginous 
or almost Vermillion exuviae, readily exposed by rubbing. Re- 
moved from the bark, the scale leaves a conspicuous white patch. 
Male scale oval, broad, with covered exuviae and a white dot and 
ring. 
Female, broad oval, with a deep constriction between head and thorax; 
the thoracic segments also strongly marked by lateral constrictions. Color 
bright orange ; caudal margin stained with dark red brown. Anal orifice 
extremely small, level with second dorsal gland of first row. Five groups of 
circumgenital glands ; median 4, anterior laterals 16 to 17, posterior laterals 
7 to 8, Dorsal pores very numerous, in four series; the first (below first 
interlobular incision) of three in a row ; the second of 17, and then after a 
short break, 9 more ; the third of over 30 ; the fourth (in an irregular line 
commencing near the 
margin ) of about 1 1 . 
Median lobes very large 
but broad and low, hardly 
at all produced; second 
lobes similar but smaller 
and more or less serrulate 
on the margin; third lobes 
represented by a small 
angular prominence ; 
plates spine-like, the 
larger one of the first in- 
terlobular interval slightly branched ; spines quite large, chiti- 
nous thickenings of the first interlobular interval rather short 
and thick, straight, subequal, but the inner the larger. 
Habitat : Abundant on small branches of Pinus sylvestris on the campus 
of the Ohio State University, Columbus, O., collected by Mr. J. G. Sanders. 
On the leaves of the same tree are some C/iionaspis pini/oliae Fitch.
