half its length. Distal division of tarsus long, composed of from 

 fifteen short to but seven longer distinct articles.^ 

 Length 35-42 mm. 



Locality. — Cuba: Juan Guerra Sagira de Panamo; Guantanamo, 

 Arroyo Hondo. (C. T. Ramsden). Type, M. C. Z. 1753; two speci- 

 mens. Type and M. C. Z. 1754. 



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, 

 densel^>' 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 



1 The 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.
