marginal spots above and beneath, lateral margins of face, 

 a central spot to femora beneath, and lateral margins of 

 opcrcula reddish testaceous. Tegmina and wings pale 

 smoky hyaline ; less than basal half of tegmina and more 

 than basal half of wings black, these black areas with some 

 obscure longitudinal reddish-testaceous streaks, and the costal 

 areas beyond them more or less piceous. Head broad, in- 

 cluding eyes wider than base of mesonotum ; face broad 

 and subglobose ; rostrum just passing the intermediate cox£e; 

 opcrcula reaching the third abdominal segment, their basal 

 inner margins moderately straight and contiguous, and then 

 obliquely divergent to apex, which is situate near lateral 

 abdominal margin.

 face and a somewhat broken transverse fascia between eyes 

 piceous ; pronotum with the lateral and ])osterior margins 

 paler, sometimes greenish ochraceous, the disk with a central 

 longitudinal piceous fascia, which is sometimes subobsolete ; 

 mesonotum with four central spots on anterior margin, a long 

 fasciate oblique sj)ot on each lateral area, and a small spot in 

 front of each anterior angle of the cruciform elevation piceous

 and costal area, basal cell, and claval area dull pale ochra- 

 ceous, venation ochraceous on about basal half, fuscous on 

 remaining area, the transverse veins at the apices of the 

 upper three ulnar areas a little piceously infuscated, and a
