our winters. They have large, usually dark scales with covered 
exuviae. ‘The last segment of the female presents no incisions, 
but instead, rather long, chitinous thickenings and_ strongly 
branched plates.

Scale of female: Circular, 2mm. diam., convex; nipple-like exuviae 
gray, surrounded by a ring of light reddish-brown; remainder of scale 
dark-brown to almost black. 
Scale of male: Similar to scale of female in color, excepting long 
posterior gray flap. Diam. 0.6—0.8 mm. 
Female: Three pairs of well-developed lobes; the median and 
second pairs are abruptly narrowed midway on their lateral margin; 
the third pair have two or three notches on the lateral margin. Six 
chitinous, linear to spatulate processes extend anteriorly from either 
margin of the three pairs of lobes. Chitinous processes on lateral 
margin of median and second lobes and on mesal margin of third lobe, 
longest. Margin of entire segment thickened with chitin, ending 
posteriorly in a broad, serrate lobe laterad of third lobe. Plates 
deeply fringed, conspicuous, slightly longer than lobes. Between 
median, and between median and second lobes, two; between second 
and third, three, and outside of third lobe are three compound fringed 
plates. The short spines on the ventral surface are situated on the 
lateral margins of each lobe including the apparent fourth lobe. On 
the dorsal surface, the spines are situated mesad of the corresponding 
ventral spine, except that they are wanting upon the median lobes. 
Dorsal pores numerous in three series; first (between median and 
second lobes) of 3; second in double row of about 20; third of about 23. 
Four groups of circumgenital gland-orifices; anterior lateral, 7—9; 
posterior lateral, 4—5.
