«ul)truucate at the apex and having the margins of the same con- 

 verging distad. The female is not so readily separated, but it is 

 hardly likely to be confused with anything but catinata, the charac- 

 ters of difference from which are given in the diagnosis. This is 

 peculiarly a mountain form, the ]\Iarathon locality being very close 

 to the foot of mountains in conditions not at all desert-like. The 

 last-mentioned locality was the only place in Texas where it was found 

 .associated ^nth another species of the genus (D. hrevihastata) , which 

 there far outnumbered the present form. The large tegmina of the 

 male are quite characteristic of oreoeca, which in the male sex and in 

 •the intensively colored female is remarkably pretty.

Description of Type. — It seems necessary only to state characters 

 not fully in accord with those of oreoeca. Size moderate. Eyes very 

 prominent, ovate, their depth contained one and one-third times in 

 that of the infra-ocular portion of the gense. Pronotum hardly 

 sellate; disk of pronotum with median width very slightly more than
