as the slightly expanded tip, which is incurved and has the lower api- 

 cal angle produced to an acutangulate apex, which is also slightly de- 

 curved, the whole almost as long as the supraanal plate; subgenital 

 plate a little bullate, short and broad, the upper margins in the same 

 plane, broadly rounded as seen from above, entire, the apical face with 

 a bluntly conical, moderate, submarginal tubercle.

This species is more nearly related to P. glacialis than to P. varie- 

 gata, differing from the former most noticebly in the color of the hind 

 femora and tibiae, and in its relatively longer male cerci with their 

 decurved tip. 



MELA NO PLUS Stal. 



As already stated, all the new Melanopli that have been noted, 

 with two exceptions, belong to this dominant genus. They will be 

 brought under the several series to which they belong, and the tables 

 for the determination of the species remodeled to introduce them. 

 The number of species is now increased to upward of one hundred 

 and fifty, thus surpassing all other North American genera of Orthop- 

 tera, but no new series are required to accommodate the additions, 

 most of which are brachypterous. 



Flabellifer Series. 



A single Californian species is added to this series, its nearest neigh- 

 bor being another Californian form, from which it may be separated 

 by the following table of the short-winged species of this series, in 

 modification of that given on pp. 124-125 of my Revision.

.MELANOPLUS. 



a\. Tegmina al)out half as long as the abdomen and much longer than the 



pronotum discolor Scudd., si77iplex Scudd.* 



d^. Tegmina shorter than the pronotum. 



b^. Furcula of male only as long as the last dorsal segment; cerci in 

 apical half equal and deeply sulcate longitudinally, so as to appear bent 



at right angles rileyanus McNeill. 



^2. Furcula of male one-fifth as long as supraanal plate ; cerci in apical 

 half tapering, not sulcate blandus sp. nov.
