Mr. B,. I. Pocock on neio Species of CMlopoda. 163 



One specimen from Caraccas, presented by Dr. Ernst j a 

 second ticketed Brazil. 



Resembling iV. mexicana^ Sauss., in its indistinctly multi- 

 articulated tarso-metatarsuSj but differing at least in the spine- 

 armature of the anal legs. Thus in N. mexicana tliere is a 

 row of three spines on the lower surface of the tibia and the 

 upper inner edge of the femur is armed with spines which 

 appear to be but little smaller than those along the under 

 surface of this segment. In N. Ernsti^ however, the tibia of 

 the anal leg is unarmed and the armature of the upper inner 

 edge of the femur consists of spinules which are very much 

 smaller than the spines on the lower surface. The figure and 

 description of A^. mexicana furnish no information with 

 respect to the sulci of the head, tergites, or sternites. 



In the specimen from Brazil the anal legs are shorter than 

 in the one from Caraccas, and the tarso-metatarsus is a little 

 shorter than the femur, patella, and tibia. 



Neioportia hrevipes, sp. n. 



Colour testaceous or pale ochraceous ; head and maxilli- 

 pedes castaneous. 



Body moderately robust, attenuated posteriorly. 



Head with posterior and postero-lateral borders strongly 

 convex, sparsely hairy, and sparsely punctured, marked in 

 its posterior half by two fine anteriorly converging sulci. 



Antennce thick at the base, the three basal segments 

 hirsute, the rest pubescent. 



MaxUlipedes Sj)arsely punctured and hairy ; anterior border 

 of the cox« not produced, nearly straight, lightly excised in 

 the middle, with a wide, very short, dentiform plate on each 

 side ; femur unarmed. 



Tergites. — The first marked in its anterior half with a 

 transverse semicircular sulcus, the area defined by the sulcus 

 being a segment of a circle, this portion only very indistinctly 

 marked with longitudinal sulci, the portion posterior to the 

 transverse sulcus furnished with two fine subparallel sulci ; 

 the second and twenty-second bisulcate, the third to the 

 twenty-first quadrisulcate, as in Cryptops ; the median area 

 between the two complete sulci longitudinally depressed on 

 each side of the middle line ; margins unraised. 



Sternites trisulcate, the median sulcus anteriorly and poste- 

 riorly abbreviated, the lateral sulci extending from the sides 

 of the anterior border to a point on a level with or slightly 

 beyond the joint of the legs ; a few of the sternites towards 

 the posterior end of the body marked in their posterior half
