34. ACRIDIUM RUBIGINOSUM. Harr. 
Facial carinae prominent, diverging but slightly; frontal costa sul- 
cate its entire length, thickly punctured. Pronotum with a prominent 
median carina, continuous and slightly arched; scarcely expanding pos¬ 
teriorly; transverse impressions dim. Elytra and wings about as long 
as the abdomen; posterior femora of the female a little shorter.

opaque, rather paler on the overlapping portion, without spots, or 
sprinkled over with dim, small, dusky spots. Wings transparent, 
slightly reddish toward the tip; veins blackish. Posterior femora red¬ 
dish; the flat disk whitish, with a row of black dots above and below; 
apex with a lunate, black spot on the side. Spines of the tibiae whitish, 
tipped with black. 
Length of female 1.4 to 1.6 inches; male much smaller. 
This is a rather rare species, and is found -only in the region of 
oak forests or groves, at least such has been the result of my obser¬ 
vations. 
35. ACRIDIUM EMARGINATUM. Uhler. 
This species is closely allied to A. alutaceum , Harr., which it re¬ 
sembles very much. 
Frontal costa sparsely punctured; lateral carinae of the face slightly 
divergent. Pronotum densely, and on the anterior lobes coarsely punc¬ 
tured; posterior lobe expanding moderately. Elytra passing the ab¬ 
domen one-fourth their length; nervules prominent. Posterior femora 
about as long as the abdomen. Prosternal point stout, cylindrical, 
obtuse, slightly bent backward. Cerci very broad, somewhat notched 
at the apex. Pulvilli remarkably large, oblong-ovate.
