Alleghanies, By E. D. Cop 
PETASERPES, Cope. 
Head concealed to the bases of the antenne by the shield-like 
expansion of the scutum of the first annulus. Ocelli two, beneath 
the margin of the same, and at the approximated bases of the an- 
tenne ; the latter large, stout, hairy, six-jointed. Annuli without 
lateral processes, each with two pores, forming two rows on each 
side of the body. 
Petaserpes rosalbus, Cope. 
The segments of the body are flattened below, and gently convex 
above; their lateral pirre is a little greater than the length of 
the extended feet; each elicate impressed line near the 
posterior margin, whic pie e the extremity, producing the 
semblance of a longitudinal angle. The extremital margins are 
entirely contin The epu diameter contracts very rapidly 
at both extremities, and the anal annulus and head are. relatively 
the segment of i a hollow sphere. The anterior aspect is horizontal, 
of the head. The antennz are of remarkable size for the head, and 
originate near together, just at the inferior margin of the basilar 
segment. Just within and above them, at their base, is situated on 
mulation of a light-coloured deposit between the elevations. The 
antenns possess six joints, of which the antepenultimate is a little 
the shortest; they become PoE. EUN towards the extre-

The reproductive organ of the male is a s sabglobilar body on a short 
pedicel, hairy except the convex extremity, which is smooth. On 
the inner side two short pedicels support each a short curved spine, 
one curved backwards and another forwards. 
The annuli are smooth. The anal onu is small, and for the 
greater part overroofed by the gom. which is broader than

The number of the annuli in the adults I find e be fifty-three 
down to fifty-one. In specimens a little smaller there are forty- 
six and forty-four; and in the smallest and palest-coloured, hence 
younger, the number ranges from forty-three to thirty-nine.
