ernsti] vornehmlich durch den Besitz eines winzigen Klaue am Ende 

 der Tarsengeissel zu unterscheiden. Ich glaube kaum das es sich 

 hier um eine artliche Verschiedenheit, sondern um eine individuelle 

 RiAckschlagsbildung handelt, die im interessanter Weise die Her- 

 kunft der Newportien aus Formen mit Klauen tragenden Analbeinen 

 demonstriert." 



But this author is clearly mistaken in regarding the claw thus as an 

 individual atavistic variation, inasmuch as a normal and well-devel- 

 oped claw is present in all the specimens secured in the type locality 

 by Mr. Mann (Plate 2, fig. 4). In Newportia ernsti, occasionally a 

 very small and wholly straight chitinous point may occur at the tip 

 of the tarsus (Plate 2, fig. 5), but apparently never a true claw or any- 

 thing that might be regarded as properly transitional to the condition 

 in avmzonica. The spining of the prefemur, etc., is also constantly 

 different, there being in all the specimens examined but four ventral 

 spines instead of six, these being also relatively considerably larger.

Localities. — State of Amazonas : Manaos !, Porto Velho ! (Mann 

 and Baker). State of Matto Grosso: Madeira-Mamore R. R. camp 

 39 on the Rio Madeira (W. M. Mann). 



Numerous specimens were secured at Manaos and several at each 

 of the other two places indicated. Closely related to the preceding 

 species. 



Newportia paraensis, sp. nov. 



Color yellow of a reddish tinge, with the most caudal plates darker. 



Head with prosternum and prehensors and the first dorsal plate 

 reddish brown. Antennae yellow, darkest proximally. Head with 

 punctations distinct and numerous, not fine, more sparse in frontal 

 region, particularly in a transverse band across its caudal portion. 

 Two median sulci distinct forward to middle of plate and not crossed 

 by any transverse sulcus; a median longitudinal furrow from anterior 

 margin a little distance caudad. Caudal margin widely convex, a 

 little incurved right of middle portion of sides straight and parallel; 

 caudal corners widely rounded.
