NEWPORTIA OREINA, Sp. nov. 
General color clear yellow to light brown. Head and prosternum 
light brown or testaceous. Legs mostly clear yellow, the caudal pairs 
darker, more orange. Antennae brownish yellow. 
Body very slender; narrowed from near the caudal end cephalad 
to the second dorsal plate. 
Head smooth and shining, not distinctly punctate. A short, chiti- 
nized median sulcus extending from the anterior margin. A pair of 
parallel sulci, one a little each side of median line, extending from 
caudal border only a short distance cephalad; no transverse sulcus. 
Median portion of caudal margin straight, the margin bending forward 
at sides about the well-rounded caudal corners. 
Antennae short; articles seventeen. Articles distad of the fifth, 
densely clothed with very short fine, straight hairs, the hairs on the 
more proximal articles longer and more sparse but none of the articles 
glabrous. 
Anterior margin of the prosternum with a slight acute emargination 
at middle. A very short, narrow chitinous plate each side of the 
indentation, the edge of which is straight and slants a little caudad 
of ectad. Two well-separated longitudinal sulci which extend 
cephalad to a little distance caudad of the anterior margin where 
they are united by a weaker transverse impression. 
First dorsal plate with the cervical sulcus angular at middle, the 
vertex lying in a moderate depression; lateral portions of sulcus 
covered by the cephalic plate. The longitudinal sulci distinct, 
converging cephalad and bifurcating to form a w-shaped mark the 
ends of which terminate on the transverse sulcus in the usual way; 
commonly a fainter transverse sulcus connecting the caudal angles of 
the w-mark and extending slightly ectad on each side. Longitudinal 
sulci of second dorsal plate gently converging cephalad and near 
1The right leg of one specimen has the tarsus of the Scolopendrides type, the 
divisions being indistinct and irregular. The tibia of the same leg is of abnormal 
form, being somewhat bowed ventrad and distinctly constricted toward distal end. 
The leg is probably a regenerated one.
