 submaculata, differing as follows: Ninth tergile with the lateral horns very short and 

 broad, the tips acute, not long and tapering as in suhmaculala; outer pleural appen- 

 dage short and broadly flattened, the apex subtruncated, with a few coarse setigerous 

 teeth, in submaculata this appendage is more slender, tapering to the acute point, at 

 about midlength on the outer margin with a prominent spine to produce a bifid appear- 

 ance; gonapophyses broad and flattened at the base, the slender tips short, not long 

 and sinuous as in submaculata ; eighth sternite with a pair of strong reddish fused 

 bristles that are decussate, in addition to the smaller seta;. In the female, the sixth 

 and seventh tergites are dark brown, the ovipositor acute, the tergal valves being 

 especially long and slender.
