Methuen, Mass., Oct. 3, 1897, in nests of Lasius mnericanns Em., " completely con- cealed in ii round ball of cottony down, attached to roots of grass entering the ants' nest. under a stone" (King).
A sinking characteiistic of this species is that the antennae and femora hear numerous long, slender hairs and that the body also bears numerous long, slender hairs. The
relative lengths of the segments of the anten- nae are much more constant than is usual in ants' nest coccids.

Upper row of spines (i) nith short shaft on joints 5-12, an unpnirecl dorsal spine on jointii 12 and 13 ; none on the anal plate; four rows of spines on joints 3 to 6 and 11, three on the other segments. Secondary hairs abun- dant, fine, white. Black, head shining;
body thickly covered with small yellow dots, approximate, subconfluent, centered by the secondaiy hairs. An indicated subdorsal, lateral and broader stigmatal yellow hands, showing as dots in the incisures which are mostly otherwise free from the yellow dots. Spines black, the basal ones on each shaft yellowish. Leg plate black; venter ft little reddish.

Lafg'e larva. Head 2.6 mm., rounded,
black, with many coarse white setae both primary and secondary; small, not as high is joint 2. Body cylindrical, uniform, feet normal. On thorax four tubercles, on abdo- men three on ciicli side of each segment, two onlyon the ninth abdominal, one on the tenth (anal plate), all paired, no median ones. Tubercle i on joints 4, 5, and 12 slightly prominent, the others rounded and about as long as wide, the lower row flat, indicated only by the hairs. They hear few stiff white hairs with black annulus. Skin rather
thickly covered with white secondary hnirs, less coarse than the primary ones, directed obliquely backward. Color black, a dorsal hand of yellow dots eacli centered by a sec- ondary hair, absent in the incisures; a white subdorsal line (below i) broken into dashes; a wavy substigmata1 white line; warts dxrk red. Many of the secondary haira arise from faiut whitish dots; leg plates reddish hlack. Pupa. Head piece with a. central ridge;
antenna cases large, strongly segmented; abdomen with three moveable incisurcs,
square, subfurcate at tip with two remote clusters of spines. Whole surface coarsely shagreened, the posterior dorsal edges of the abdominal segments also pitted. Color
bronzy brown, the incisures blackish. Length 23 mm., width 9 mm.

Lecaniwn ti~~,gidztm is quite common on
both Magnolia glauca and M gra-ndiflora

April in considerable numbers. These crawl out on the new wood and leaves of infested branches, frequently almost covering them. Proportionately few of these reach maturity, however, as they are attacked by a ni.n-nber of parasites. The life cycle appears to be about one year.
