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 
Riickschlagsbildung 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 amazonica. 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: Mandaos!, 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 Mandéos 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.
