Thoracic seginents (fig. 4a), taken together, with the lateral margins parallel excepting in front
and behind, as the margins of second segment converge somewhat from near the front end to the hind
margin, while those of seventh segment converge in the opposite direction. Second segment some-
what or considerably shorter than the third, below a little behind the front angle with a somewhat
small, subacute process directed mainly forwards (fig. 4b). Third, fourth and sixth segments nearly
equal in length, nearly as long as broad and only a little shorter than fifth segment. — Thoracic legs
somewhat short. Second pair (figs. 4b and 4d) with fourth joint distinctly longer than the fifth and
without setae; seta on the anterior angle of fifth joint somewhat short; sixth joint a little shorter than
fifth and fourth joints combined, and the seta on the anterior side stiff and only a little longer than
the diameter of the joint; seventh joint with claw about as long as fourth joint; the third joint on
the posterior side with an extremely long, strong seta reaching the end of fifth joint. Third pair with
the seta on third joint proportionately still longer than that on second pair; fourth, fifth and sixth
joints conspicuously shorter than in second pair, but preserving the same proportion as to length and
similarity as to setee; seventh joint with claw considerably less than half as long as sixth joint. Fourth
pair with the same enormous seta on third joint. Seventh pair (fig. 4e) is rather robust; second joint
expanded, only about twice as long as broad; third joint scarcely distinguishable; fourth and fifth
joints much widened, with curved rows of very fine spines on the outer side and on the convex
margin; sixth joint is not much longer than the fifth, with some five minute incisions along the
longest margin and at the end with a long seta and two strong, moderately long spines pectinate
along the concave margin; seventh joint very short and the claw minute. Sixth pair of legs are a
little, and fifth pair somewhat, more slender than seventh pair, with seventh joint conspicuously longer
and thinner, while fourth and fifth joints are adorned in the main as in seventh pair.
