ter (1804) in the first volume of Occasional Papers issued by that insti- 
tution. Two hundred and twenty-six species are noted as already de- 
scribed, but from localities not previously known. Of these 73 were 
were found in the Calamianes Islands—all of them identical with spe- 
cies found in Palawan. 
M. A. Pettit, having had an opportunity of examining the supra- 
renal capsules of two adult Ornithorhyncus (O. paradoxus) makes the 
following statements in regard to them. In size and general appear- 
ance the suprarenal capsules of Ornithorhyncus resemble those of 
mammals, while their position, within the posterior extremity of the 
kidney, is an Avian character. (Bull. Soc. Zool. de France, T. XIX, 
1894). 
ENTOMOLOGY.’ 
A new Tettix.—In a series of specimens of Tettigids received from 
Mr. J. C. Warren of Palouse, Washington, I find a new form, see Fig. 1, 
nearly allied to Tettix granulatus but having certain recognizable 
differences as here described. 
Tettiz incurvatus sp. nov. Resembling Tettix granulatus nearly but 
differing as follows: Average length shorter, more robust, pronotum 
faintly bulging and deeper over the thorax, lateral angles more pro- 
nounced, median carina of pronotum distinctly elevated reaching the 
maximal height over the shoulders, a small swollen space here intercept- 
ing the base leaves the carina just in front sharply compressed, con- 
vexly sloping to the front, with a depression on each side—this is barely 
indicated in T., granulatus. Dorsal -front and lateral front margin of 
pronotum encroaching on the head. Face broader, cheeks more 
swollen. Surface of pronotum densely granulated interpersed with 
fewer coarse granulations. Color dark brownish fuscous tending to 
black. In the male the wings slightly over reach the pronotum from 
4 to 1 mm.; in the female this condition varies, the wings slightly 
over reaching the pronotum in some cases, in other individuals the 
reverse is true. Specimens of T. granulatus from Indiana, Illinois and
