Female. Though the male of this species is not unconimon I am 

 not at all sure with regard to the female. I possess only two speci- 

 mens, which I refer with some doubt to this species. They have 

 green eyes with three bands, a yellowish frontal band with almost 

 parallel horders, and a low frontal callus, a Iittle rounded upwards. 

 The third joint of the antennæ is moderately dilated. The palpi are 

 almost as in nwntamis or only vei-y slightly thicker. The jiræalar 

 callus is reddish. hi both speciniens the abdonien is mostly grey. 

 with only some reddish markings on the second and third segments. 

 The venter has a hroad. dark middle line and the four last seg- 

 ments dark. 



Length 13 to about 15 mm.
