regards as allied, and from these and his descriptions and figures I 

 should judge that all belonged to the gerontogeic Calopteni, rather 

 than to the Melanopli. It is at least prett)' certain that they do not 

 belong to Podisma. 



Among the more interesting of the Acridiidse obtained in Ore- 

 gon in the summer of 1897 by Mr. A. P. Morse was an apterous spe- 

 cies of Podisma, the apterous section of the genus having heretofore 

 been known in America only from the extreme east. The table 

 in my Revision (p. 97) may be thus recast, so far as the apterous spe- 

 cies are concerned, to accommodate the new form : 



TABLE OF THE APTEROUS NORTH AMERICAN SPECIES OF PODISMA. 



ai. Smaller species. Hind tibiae green or greenish ; lower ajjical angle 

 of male cerci angulate, but not decurved. 



b^. Hind femora conspicuously fasciate with fuscous; cerci very slender, 

 in the middle distinctly less than half as broad as the liase. 



7'ariegata Scudd. 

 U^. Hind femora almost uniformly green ; cerci relatively stout, in the 

 middle distinctly more than half as broad as the base. . . .glacialis Scudd. 

 if'. Larger species. Hind tibiae yellowish d^) or reddish (9 ) ; lo>ver api- 

 cal angle of male cerci distinctly produced and decurved. . . .polita sp. nov. 



odisma polita sp. nov.

Dark olivaceous green, more or less flavous beneath (cJ'), or testa- 

 ceo-olivaceous, so heavily flecked and i)unctate with fuscous as to ap- 

 pear griseous, pale testaceous beneath ($), the sides with a broad, 

 postocular, piceous band extending across the pronotum, enlarged 

 upon the metazona and continued as a fuscous or piceous belt back- 

 ward nearly to the end of the abdomen, at least in the male. Head 

 olivaceo-testaceous, more or less heavily or lightly flecked with fuscous, 

 heavily on summit, the postocular band edged narrowly above with 

 testaceous; vertex slightly tumid, scarcely elevated above the prono- 

 tum, the interspace between the eyes twice (cJ*) or fully twice (9) 

 as broad as the first antennal joint; fastigium considerably declivent, 

 scarcely arcuate, lying wholly below [<S) or at (?) the upper level of 

 the eyes, so as not to be wholly seen on a side view, slightly (cJ*) or 

 scarcely (?) sulcate, angularly expanded laterally in front; frontal 

 costa percurrent, subecpial, faintly expanded between the antennae as 

 seen from in front, a little (c?) or distinctly (9) narrower than the
