BRAZILIAN ORTHOPTERA 
external line of fuscous, these often subobsolete, the genicular arches occa- 
sionally blackish-brown; caudal tibiae with or without points of blackish- 
brown at the base of each marginal spur; caudal tarsi similarly with or without 
the entire second and apex of third joint blackish-brown. A single pair from 
Tijuca have a very recessive type of coloration, the pronotum in both sexes 
and the tegmina in the female as well being yellow ocher. 
(type): length of body, 5 mm.; length of pronotum, 1.2; greatest (caudal) 
width of pronotum, 2.1; length of tegmen, 4.1; greatest width of dorsal field 
of tegmen, 2.2; length of caudal femur, 4.2. 
9 {allotype): length of body, 5.2 mm.; length of pronotum, 1.2; greatest 
width of pronotum, 1.5; length of tegmen, 3.1; greatest width of dorsal field 
of tegmen, 1.4; length of caudal femur, 5; length of ovipositor, 1.8. 
In addition to the type and allotype we have examined six 
paratypes (three males and three females) from the same general 
region and the same collection. These were taken at Petropolis 
(1 cf , 1 9 ) and Tijuca (2 cf , 2 9 ) on the dates given above for 
the type and allotype. As we have said above under color com- 
ments, all the material has been injured through color change or 
breakage of parts. In addition to these we have before us five 
females from La Piedrita, Venezuela, taken February 16, 1911 
(S. Brown), and a single female from Para, state of Para, Brazil 
(C. F. Baker), in the collection of the Academy. This material 
from Venezuela and northern Brazil shows certain features of 
difference, as somewhat shorter form, more robust palpi and ap- 
parent color tendencies, which may make it necessary at a future 
date, when more and perfect material is at hand, to separate the 
more northern insects, but for the present it seems best to permit 
them to remain under pulex. We do not, however, consider 
them paratypes of the new species. In the allotypic female we 
find four external marginal spurs on one caudal tibia,^- all the 
other specimens have three. In all the material the perforation 
of the cephalic tibiae is as described, and in none are the wings 
developed. 
The genus Symphyloxiphus also contains the two species 
described from western Ecuador by Chopard as Anaxipha riveti 
-and A. bicolor . The latter is clearly a member of the jiresent 
genus, extremely close to, if distinct from, S. magnificum (the 
genotype), and we have no hesitation in assigning it without 
This specimen has but a single caudal limb remaining.
