fingers, extending over the basal fifth of the supraanal plate ; cerci 

 broad, laminate, torqueate, broadening on the basal third, where they 

 are about two-thirds as broad as the hind femoral geniculation, then 

 at once and regularly narrowing to half that width almost wholly by 

 the excision of the lower margin, the apical portion strongly incurved, 

 turned over the lip of the scoop formed by the subgenital plate, and 

 twisted, but not abruptly, at right angles to the basal portion, the apex 

 rounded, the upper margin nearly in one plane throughout but 

 strongly arcuate ; subgenital plate broad and nearly equal, especially 

 where uniting with the lateral margins, the whole flaring faintly along 

 the upper margin. 



Length of body, 15 mm.; antennae, 6 5 mm.; tegmina, 3 mm.; 

 hind femora, 9.5 mm.

This species is closely allied to M. rileyanus, found at lower levels 

 in Los Angeles County, but differs from it in the longer furcula, and 

 in the anal cerci, which are not equal in the apical half nor externally 

 sulcate, so as to appear longitudinally bent at right angles, as in M. 

 rileyanus. ' 



BowDiTCHi Series. 



Prof. C. F. Baker has sent me from Colorado a single specimen of a 

 species of this series, which differs clearly from the others in the ele- 

 vation and notching of the apical margin of the subgenital plate in 

 the male. In order to bring it next its nearest ally, M. bowditchi, 

 the table for the determination of the species in this series, as given 

 in my Revision (p. 131), needs to be slightly remodelled, as follows : 



TABLE OF THE SPECIES IN THE BOWDITCHI SERIES OF MELANOPLUS. 



aS. Subgenital jjlate of male distinctly elevated apically above the lateral 



margins, and notched incisus sj). nov. 



a2. Subgenital plate of male not or hardly elevated apically above the lat- 

 eral margins, and entire. 

 b^. Body, tegmina and legs brown or testaceous, the hind femora gener- 

 ally banded with dark colors. 



(-1. Forks of the male furcula more or less obliquely or transversely 

 truncate at tip and given an oppositely hooked appearance by the 

 rounded excision of the inner margin ; hind femora generally distinctly 

 banded. 



^1. Rather uniform in coloring, the lateral lobes with no l)right
