female. Eyes distinct. Beak rather short and thick, last two joints 
longer than basal portion. Fore wings with the stigma large, the cubital 
simple, obsolete basally, Ps two discoidals united at base. Hind wings 
without discoidal vein. 'T'wo distinct tarsal joimts and two claws on all 
the legs. Anal plate flattened, drawn forward dorsally and compressing 
middle of posterior segments, cauda short, transverse, inconspicuous. 
Cornicles and excretory glands wanting. 
G. squamosa, ni. sp. 
Wingless Viviparous Female (Plate IX., Fig. 5 and 6).—Body 
broadly ovate, more or less distinctly and widely margined, sutures dis- 
tinct, surface alutaceous. General color whitish to pale straw-color, coy- 
ered with a mealy excretion. Entire surface, including ‘antenne and 
legs, with hght brown points from which arise short thick scale-like 
hairs, the basal half of each erect, but near middle strongly and often 
almost rectangularly bent backwards, the apical half of those on the 
vertex apparently flattened and expanded; a large brush of hairs at tip 
of abdomen. In alcoholic specimens, a varying pattern of dark brown 
longitudinal lines radiating from the cauda, above and below, usually 
four each side of middle, which unite on each side at the base of the ab- 
domen, and often extend upon the thorax as a single stripe; lines usually 
dilated at the sutures. At the base of the abdomen the inner pair di- 
verge; the outer pair are more isolated. A similar marking is some- 
times seen in other species; it relates perhaps to internal structure. 
Head short, a small brown spot each side of middle, and an indis- 
tinct pale median line. Antenne robust, attaining the side of the meso- 
thorax, usually five-jointed in the adult, but joints IIT and IV often 
coalesced more or less, the point of union marked by a distinct constric- 
tion. The apex is faintly fuscous. I and IT are subequal, about as long 
as thick, rounded, I very slightly thicker than II, remaining joints 
nearly as thick as IIT; III longest, nearly or quite as long as I and II 
combined; TV about as long as IL; V longer, but not as long as ITT, 
apical spur short and thick, its diameter nearly half that of the joint, 
and slightly longer than thick, its length being about one fifth the entire 
length ‘of the joint. At the apex of IV is a round sensorium, and at 
the base of the spur of V, and partly encircling it, is a rather large Ju- 
nate-reniform one, with a minute one between it and the spur, the lat- 
ter group especially surrounded by dense minute pubescence. Other 
joints without sensoria. Eyes very small, black. 
Prothorax broad, not constricted, with a brown impressed pit at 
the middle of each half dorsally; remaining body segments with brown 
spots and transverse lines in the sutures, two longitudinal series usually 
distinct, one at the inner limit of the impressed margin, the other about 
one third of the width of the body from each side. No trace of corni- 
cles. Anal plate large, longitudinally oblong, subtruncate at tip, flat- 
tened above, fuscous, strongly retracted among the dorsal segments just 
preceding, and but slightly projecting behind, the cauda represented 
only by a small transverse plate at base; preceding two or three seg- 
ments strongly arcuate, brown at middle.
