BRAZILIAN ORTHOPTERA 
We are referring this specimen tentatively to peruvianus. It 
agrees with the description very well, yet has the tegmina slightly 
broader mesad (3.6 mm. instead of 3); however, as the whole 
insect is somewhat larger than Brunner’s measurements this 
difference may be entirely proportional. 
Ceraia grandis new species (Plate III, figs. 4 and 5.) 
Apparently related to C. tibialis and maxwia Brunner, the 
former from Fonteboa, upper Amazonia, the latter from Sorata, 
Bolivia; differing from tibialis in the less arcuate ovipositor, less 
strongly spined ventral margins of the caudal femora, broader 
tegmina and certain features of the coloration, such as the 
absence of blackish from the caudal tibiae. From maxima, to 
which it is apparently more nearly related, the new form can be 
distinguished by the shorter caudal femora, more numerous teeth 
on the ventral margins of the same, the shorter ovipositor and the 
non-ferruginous caudal tibiae. The male sex of both of the older 
species is unknown, so comparisons have been made solely on the 
basis of the female. 
Type. — d' ] Porto Velho, Rio Madeira, Brazil. (Stanford 
Expedition; Mann and Baker.) [Acad. Nat. Sci. Phila., Type 
no. 5299.] 
Size very large (equal to some individuals of the genus Stilpnochlora): form 
subcompressed: surface moderately polished. Head with the occiijut gently 
arcuate, hardly elevated dorsad of the general level of the pronotum; fastigium 
subhorizontal, compressed, faintly sulcate, the apex weakly bullious and in 
contact with the rather elongate, subequal, facial fastigium: eyes hardly 
prominent when seen from the dorsum, nearly circular in basal outline, their 
depth faintly greater than that of the infra-ocular portion of the genae: 
antennae reaching to the tegminal apices. Pronotum with the disk deplanate, 
its greatest caudal width equal to three-fourths of the greatest length of the 
same: cephalic margin of disk very faintly arcuato-emarginate, caudal margin 
strongly arcuate, forming more than the curve of a quadrant; lateral angles 
of disk well rounded cephalad, narrowly rounded but of distinct character 
caudad; surface of disk sparsely impresso-punctulate, particularly caudad, 
with the median figure very broadly U-shaped, the caudal section of the disk 
somewhat depressed below the general level: lateral lobes of the pronotum 
with the greatest depth surpassing the greatest length of the same, cephalic 
margin sinuate, ventro-cephalic angle, ventral margin and ventro-caudal angle 
regularly and stronglj' arcuate, caudal margin arcuate, humeral sinus rotundato- 
rectangulate. Tegmina with their length slightly more than six times that 
of the pronotal disk, in form rather elongate lanceolate, the greatest width
