BRAZILIAN ORTHOPTERA 
cinnamon-brown, the apex of the abdomen of the male, including the subgenital 
plate and cerci, fuscous. Ocelli light ochraceous-buff ; antennae ochraceous- 
buff to buckthorn brown, washed with fuscous at proximal third, this area 
showing sparse, very fine annuli of the base color; eyes clove brown. Lateral 
field of the tegmina washed with mummj^ brown to fuscous. Cephahc tibiae 
touched with bister. Median femora with the proximal two-fifths light 
ochraceous-buff; median tibiae becoming bister. Caudal femora fight och- 
raceous-buff proximad, the distal half and the dorso-proximal section fuscous. 
Ovipositor chestnut, narrowly margined laterad with blackish brown. 
d'{type). Length of body, 12.5 mm.; length of pronotum, 2.3; greatest 
(caudal) width of pronotum, 3; length of tegmen, 13; greatest width of teg- 
men, 4; length of caudal femur, 7.2. 
9 {allotype). Length of body, 12.3 mm.; length of pronotum, 2.3; greatest 
(caudal) width of pronotum, 3; length of tegmen, 13.2; greatest width of 
tegmen, 3; length of caudal, femur, 7.3; length of ovipositor, 4.6. 
The type and allotype are the only specimens of this striking 
species examined by ns. 
We take pleasure in dedicating this very interesting form to 
Theodore Roosevelt, in token of our appreciation of his scholar- 
ship as a zoologist and a historian and ability as a statesman. 
The name Roosevelt long will be associated with the Madeiran 
region as a result of the work of the Expedicao Scientifica Roose- 
velt-Rondon. 
Amblyrhethus manni new species (Plate IV. figs. 27, 28, 29, 30, 31 and 
32.) 
This species agrees with A. capitatus (Saussure) in having both 
faces of the cephalic tibiae provided with foramina, and in the 
structure of the apex of the ovipositor more closely approximating 
that species than it does the type found in the other previously 
known forms. It differs, however, from capitatus in its dis- 
tinctly smaller size, in the slightly narrower fastigium (which is 
hardly more than twice as broad as the proximal antennal joint), 
in the form of the lateral lobes of the pronotum, in the more 
numerous rami of the mediastine vein of the tegmina, in the 
caudal metatarsi having but two, instead of three, teeth on the 
dorso-external margin, in the details of the apex of the ovipositor 
and in certain features of the coloration.
