backward near the broadly rounded angles; median groove distinct 
fading out before reaching the base. Elytra with the humeri broadly 
rounded and depressed, broadly elevated around the scutellum, truncate 
at tip and minutely dentate at inner angle; two oblique depressions near 
the suture, one before the middle, the other behind it, a very faint third 
depression towards the tip; the outer half slopes obliquely from behind 
the humeri; the punctures in rows, very coarse and close together, less 
coarse and deep towards the apex; interspaces more or less convex, the 
surface shining, finely and closely transversely wrinkled. Legs slender, 
the posterior femora with a stout tooth; the posterior tibiae with the 
apical half curved inward. Mesosternum narrower than the coxa. Pygi- 
dium slightly rounded, almost truncate. Under surface clothed with 
pale yellowish pubescence. 
Types in the Illinois State Laboratory of Natural History 
and U. S. National Museum and the collection of the author. 
Localities: Fourth Lake, Lake Co., 111., 2 and 5 Aug., 1887 
(on bulrushes, Garman and Hart); Normal, 111., Sept., 1880 
(one specimen) ; Indiana (one specimen) . 
The species varies in coloration. Of the 19 specimens 
examined five are ferruginous-yellow above and below, with 
only the head green and the femora touched with the same 
color. One specimen is entirely golden green above, the 
under side of the prothorax and the margins of the ventral 
segments ferruginous and traces of the same color on the 
legs. The other 13 are the type form.

THE SPECIES OF THE GENUS CHIMAROCEPHALA AND 
DESCRIPTIONS OF TWO NEW SPECIES OF 
CALIFORNIAN ORTHOPTERA. 
BY A. N. CAUDEXL. 
The genus Chimarocephala was established by Scudder in 
1876 for four species, viridifasciata, brempennis, cubensis, and 
pacifica. In 1884 Saussure removed the first three species to 
his new genus Chortophaga, leaving only pacifica, which is 
therefore the type of Chimarocephala. At the same time 
Saussure described a new species of Chimarocephala, b^herensi 
from California, and referred to that genus his Tomonotus 
otomitus, a Mexican species described in 1861. Saussure 
separated his new Californian species from Thomas' pacifica, 
also from California, on the characters of the thorax, which
