This species resembles Mutilla ferruginata, but the head is longer 

 behind the eyes ; the thorax is also longer in proportion. It appears 

 to be more than a variety.

 men ferruginous. The vertex of the head with golden pubescence ; 

 the antennas and mandibles ferruginous, the latter black at their 

 tips. The thorax closely punctured ; short, rounded anteriorly, 

 narrowed behind the middle and truncate. The basal segment of 

 the abdomen pale rufo-testaceous, a broad elongate patch of bright 

 gold-coloured pubescence extending from the base nearly to the 

 apex ; the third, fourth, and fifth segments with black pubescence 

 laterally; beneath, the second and following segments fringed 

 with white pubescence.
