plates and the narrow chitinized ring surrounding them distinctly 
reddish; probably uniformly, moderately convex in life, without 
definite longitudinal ridge; covered by a thin, transparent, easily 
shed film of brittle wax, this appearing somewhat whitish when 
removed from the insect; maximum length of specimens ex- 
amined, 1.75 millimeters. 
Body of female-——Maximum length mounted on a slide, about 
1.75 millimeters; body clearing when boiled in caustic potash, 
except for the anal plate and marginal regions; oval, somewhat 
pointed anteriorly, lateral margins slightly lobed due to shallow 
incisions opposite the spiracles; antenne minute, rudimentary, 
indistinctly 3-segmented, the apex bearing a cluster of six sete, 
some of these nearly as long as the whole antenna; preapical 
segment with at least one long seta, total length, averaging 36 »; 
legs minute, rudimentary, broadly triangular from base to apex, 
the width at base, including the extended attachment sclerite, 
about 68 ,; the total length to apex of claw, about 25 yp, the divi- 
sions between the different parts so faintly indicated that it is im- 
possible to trace them; with numerous relatively large chitinous 
circles, these the bases for the short setze, present on the leg, claw 
present but poorly developed, both the tarsal and claw digitules 
present, relatively well developed, about 17,» long; claw, about 
5 » long; beak apparently 1-segmented, short, stout and broad; 
spiracles rather large, placed nearer the margin than the center 
of the body, each connected with the margin by a line of scattered 
pores, which passes through a chitinous thickening at the edge 
and then barely up onto the upper surface; spiracular spines 
wanting in all specimens examined and no traces such as presence 
of chitinized bases visible; marginal spine and hair arrangement 
unusual, the margin just at the edge or a very little on the dorsum 
with a row of relatively long, slender, hairlike sete, below this 
broken up by deep irregular incisions and crenulations, some of 
which extend the whole width of the chitinized portion, and 
bearing, usually on the inner portion of the chitinization, an un- 
evenly spaced and irregularly placed row of stout but long sete, 
these about half the length of the dorsal sete or a little more, 
and as much as two or even three deep at the posterior end of 
the body: dorsally with fairly numerous but scattered sete, 
similar in shape and base to those occurring dorsally at the 
margin, but smaller, present over the whole surface, Slightly 
larger near the margin than near the middle ; ventrally with more 
numerous, similar, but smaller sete, those just anterior to the 
anal plates arranged in fairly definite straight transverse rows;
