behind the eyes absent; two spots of yellow on the mesopleursB, an 

 anterior one and a smaller posterior; dorsal segments 1 to 6 of the 

 abdomen with uninterrupted apical bands of yellow and the seventh 

 segment with a spot each side; ventral segments 2 to 6 laterally at 

 apex with a spot of yellow; intermediate and posterior knees, tibiae, 

 and tarsi yellow like the anterior, instead of ferruginous, as in the 

 female; propodeum coarsely punctate. 



A female paratype is smaller than the tjrpe and differs from it in

 rated. The male agrees very well wdth the description of (Tiphia)
