 reaching metazoua, female; pronotum longer than front femora, 

 hind margin feebly rounded, carinne all cut much behind the mid- 

 dle, the lateral ones parallel on prozona, feebly divergent on meta- 

 zona, the latter one-half the length of prozona ; lateral lobes with 

 outline and margins as in Dichromorpha; tegmiua and wings mod-

 strongly widened at middle and discoidal area narrowed; hind

 ally covering three-fourths or more of abdomen, but never extending be- 

 yond its tip. Length of body, $, 1720.5, 9, 21 28; of antennae, $,
