NO. 1124. REVISION OF THE MELANOPLI SC UDDER. 133 



c'\ Breadth of subgeuital plate of male variable, but generally narrower than 

 long, its apical margin usually entire; cerci rarely less than four times as 

 long as middle breadth (when less, at least three times as long, and then the 

 apical margin of the subgeuital plate is entire), generally slender, excepting 

 sometimes at extreme base when there is great disparity in width between 

 the basal and apical halves, the basal half generally tapering considerably, 

 the apical half often much narrower than the basal, rarely showing any 

 excision of the lower margin, the apex narrowly rounded or bluntly pointed. 

 /'. Subgeuital plate of male as broad or nearly as broad at apex as at base, 

 generally elevated apically and often notched (generally narrowly) ; cerci 

 usually narrowing but little on basal half, the apical half equal and sym- 

 metrical, bluntly rounded (rarely truncate or angulate) apically. 

 1 . Apical margin of subgenital plate of male notched with greater or less 

 distinctness; cerci slender, narrower than the frontal costa, subequal. 

 straight or only gently incurved (7. Devastator series). 



/i 1 . Small species, with tegmina not surpassing the hind femora in 

 either sex; interval between mesosternal lobes of male distinctly less 

 than twice as broad as long. 



i l . Cerci of male narrowed rather than broadened apically. 

 j l . External surface of male cerci apically dimpled; furcula with 

 the tapering portion relatively broad, distinctly flattened, almost 

 reaching the middle of the supraaual plate. 



fc 1 . Prozona of male longitudinal; fingers of furcula parallel; 



cerci bent inward apically 28. diminutus (p. 190). 



fc 2 . Prozona of male quadrate; lingers of furcula divergent; 



cerci gently inonrved throughout 29. consanguineiis (p. 192). 



j*. External surface of male cerci silicate through apical third or 

 more; furcula with the tapering portion very slender, not flat- 

 tened, not nearly reaching the middle of the supraanal plate. 



30. sierranus (p. 193). 



i-. Cerci of male feebly erfj^a-rged apically rather than narrowed. 



31. ater(p. 194). 



/i-'. Medium-sized species, w^ih tegmina almost always surpassing the 

 hind femora in the male and*usually in both sexes; interval between 

 mesosternal lobes of male fully twice, generally more than twice, as 

 long as broad. 



i 1 . Tegmiua more or less, generally distinctly and profusely, mac- 

 ulate. 



j [ . Lateral lobes of prozona with a generally distinct black baud, 

 rarely broken and then by no conspicuous pale oblique stripe. 



32. derastator (p. 196). 



/-. Lateral lobes of prozona with a distinct black band, always 

 broken by a conspiuous more or less arcuate oblique pale stripe. 



33. virgatus (p. 199). 



t 2 . Tegmiua immaculate or with the feeblest possible sign of maeu- 

 lation. 



j { . Whole body, including tegmina, very light colored, having a 

 bleached appearance with no dark markings, except (and very 



rarely) dusky clouds on hind femora 34. uniformis (p. 201). 



/'. Whole body, including tegmiua, moderately dark, the lateral 

 lobes with a darker stripe and the hind femora distinctly though 



not conspicuously bifaseiate 35. angelicus (p. 202). 



g-. Apical margin of subgenital plate of male entire; cerci either 

 broad (broader than the frontal costa or fully as broad as it) and sub- 

 equal ; or else very inequal. tapering rapidly at the base and generally 

 arcuate; hind tibiae usually red.
