(j'^. Posterior femora with one light band on the inner face. Process 

 of the nietazone of the pronotum acute angular with the tip 

 sharp. 

 /(^ Basal half of the wings yellow. 



i'. Outer half of the wings infuscated tolteca Saussure. 



/-. Outer half of the wings not wholly infuscated, but the apical 

 li valine jiart nearly as broad as the fuscous band. 



j)istrinaria Saussure. 

 /(■-'. Basal one-sixth of the wings yellow, apical one-sixth hyaline, 

 remaining two-thirds occupied by the fuscous band. 



melanoptera, new species. 

 e-. Lateral lobes of the pronotum with a tooth on the posterior part of the 



lower border Californica group. 



/'. Tegmina conspicuously banded, or at least with the fuscous puncta- 

 tions well separated into three groups. 

 (j'^. Pronotum with a light stripe on either side of the disk! Fuscous 

 band of the wings narrow, about one-seventh of the length 



of the wing in width californica Bruner. 



g'K Pronotum quite plain on the disk. Fuscous band of the wings 

 broader, one-sixth or one-fifth the length of the wing in 

 width. 

 // '. Metazone of the pronotum twice as long as the prozone, with the 



process acute angulate strenua, new species. 



/( '-. Metazone of the j^ronotum once and a half as long as the pro- 

 notum with the process obtuse angulate. 



montnna Bruner, manuscript. 

 /'-. Tegmina with scarcely a trace of the usual bands, but with a few 

 scattered spots on the basal half, the rest almost plain. 



agrestis, new species. 

 d^. Posterior tibije yellow-green or brown. 



('. Lateral lobes of the pronotum with a tooth on the posterior part of the 



lower margin Pacifica groip. 



pacifica Bruner. 

 f'^. Lateral lobes of the j^ronotum without a tooth. Tegmina distinctly or 

 conspicuously banded, except sometimes in dark colored 

 specimens where the contrast may be slight; fascia large 

 and, though irregular in shape, semisolid and something 

 more than aggregations of fuscous spots. Wings yellow or 

 greenish yellow at the base with a distinct fuscous band. 

 Posterior femora with the disk of the inner face black with 



two light bands Vinculata group. 



/^ Lower sulcus of the posterior femora light, with one preapical black 

 band, or black, with two light bands, one preapical and 

 one median, the latter not merely interrupting the 1)lack 

 on the edges of the sulcus, but in the bottom as well, 

 y'. Fuscous band in its usual position in the middle of the wing. 

 Spur extending less than half way to the base. General 

 color dark fuscous brown, j^ermitting little contrast in the 

 bands of the tegmina. 

 /( ^ Metazone scarcely more than one and a half times as long as 

 the prozone. Fuscous band of the wings very broad, occu- 

 pying nearly one-third the length of the wings.
