 punctures that are separated by about 0.8 their diameter; sixth ster- 

 nite between its lateral hooks smooth ; exposed portion of subgenital 

 plate oblanceolate to spatulate, about 2.5 as long as wide, subbasally 

 with a median erect compressed teeth or with a pah of teeth, parallel 

 ridges, or elongate tubercles; subgenital plate with a few erect hairs 

 basad of or between the teeth or tubercles but none beyond. There

 teristic of different subspecies to intergrade m specimens from inter- 

 mediate areas.

 punctures separated by about 0.5 then diameter.

There are four subspecies, differing in the amount of black on the 

 abdomen and in the shape of the tooth on the male subgenital plate.
