present on the tibise of the oviparous 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, the two discoidals united at base. Hind wings 
without discoidal vein. Two distinct tarsal joints 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 want¬ 
ing.

Wingless Viviparous Female (Plate IX., Fig. 5 and 6).—Body 
broadly ovate, more or less distinctly and widely margined, 
sutures distinct, surface alutaceous. General color whitish to 
pale straw-color, covered with a mealy excretion. Entire sur¬ 
face, including antennae and legs, with light 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 appar¬ 
ently 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 be¬ 
low, usually four each side of middle, which unite on each side at 
the base of the abdomen, and often extend upon the thorax as a 
ingle stripe; lines usually dilated at the sutures. At the base of 
.he abdomen the inner pair diverge; the outer pair are more 
isolated. A similar marking is sometimes seen in other species; 
it relates perhaps to internal structure. 
Head short, a small brown spot each side of middle, and an 
indistinct pale median line. Antennae robust, attaining the side 
of the mesothorax, usually five-jointed in the adult, but joints 
III and 1Y often coalesced more or less, the point of union 
marked by a distinct constriction. The apex is faintly fuscous. 
I and II are subequal, about as long as thick, rounded, I very 
slightly thicker than II,, remaining joints nearly as thick as II; 
III longest, nearly or quite as long as I and II combined; IY 
about as long as II; Y longer, but not as long as III, 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 IY is a round 
sensorium, and at the base of the spur of Y, and partly encir¬ 
cling it, is a rather large lunate-reniform one, with a minute 
one between it and the spur, the latter group especially sur¬ 
rounded by dense minute pubescence. Other joints without sen- 
soria. Eves verv 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 longi¬ 
tudinal series usually distinct, one at the inner limit of the im¬ 
pressed margin, the other about one third of the width of the 
body from each side. No trace of cornicles. Anal plate large,.
