<•'. Hreadth of siibgenital plat*' of male v:irial»lf, but •joiierall y narrower than 

 Ion*;, its apical margin Jisually entire; ciTci rarely less thau four times as 

 loriu; a8 middle breadth (when les-s, at least three times as lonj;. an<l then the 

 apical mar<;in of the subfji-nital plate is entire), jjeuerally slender, excepting 

 Bometimt-s at extreme base wheii there is j^reat disparity in width between 

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

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

 excision of the lower margin, the apex narrowly ronndt-d or blnntly pointed. 

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

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

 iisnally narrowing but little on basal half, the a})ical half e<[nal an<l sym- 

 metrical, blnntly rounded (rarely truncate or angnlate) apically. 

 (f. Apieal margin of subgenital plate of male notrhed with greater or less 

 distinctnt'Ss; cerci slender, narrower than the frontal costa, subequal, 

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

 fc'. 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, 



%'. Cerci of male narrowed rather than broadened apically. 

 y. Kxternal surface of male cerci apically dimpled; frrcula with 

 the tapering portion relatively broad, distinctly liatteued, almost 

 , reaching the middle of the supraaual plate. 



k\ I'rozona of male longitudinal; tingers of furcula parallel; 



cerci bent inward apically 2S. d'lminutuH (\\. 190). 



k-. Prozoua of male <|uadrate; lingers of furcula divergent; 



cerci gently incurved throughout 29. consaiKjttineiis (p. 192). 



j-. External surface of male cerci sulcate through ajdcal third or 

 more; furcula with tli«< tapering j>ortion very slender, not llat- 

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



30. sierranuH (p. 193). 

 i-. Cerci of male feebly enlarged apically rather than narrowed. 



31. a/e»-(p. 194). 

 K^. Medium-sized species, with tegmina alnost always surjiassing the 

 hind femora in the male and usually in both sexes; interval lietween 

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

 long as broad. 

 i^. Tegmina more or less, generally distinctly and profusely, mac- 

 ulate. 

 j\ Lateral lobes of prozona with a generally distinct black band, 

 rarely broken and then by no conspicu'ms pale oblique stripe. 



32. (urastaior (p. 196). 

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

 broken by a conspiuous more or less arcuate obli(ine pale stripe. 



33, vir<jatus (p. li>9). 



t^ Tegmina immaculate or with the feeblest possible sign of macn- 



lation. 



_/■'. Whole body, including tegmina, very light colored, having a 



bleached ap))earance with no dark markings, except (and very 



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



_/-. \Vh<de body, including tegmina. moderately dark, the lateral 

 lobes with a darker stripe and the hind femora distinctly though 



not conspicuously bifasciate 35. aiitjeliciis (p. 202). 



g-. Apical margin of snbgeuital i)late of mab; entire; cerci either 

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

 equal ; or el>e very ineqnal. tapering' rapidly at the base and generally 

 arcuate; hind tibiae usually red.
