licae as this species has the inner lower frontal bristles nearer to the 

 middle than to the eye-margin, only one pair of supraantennal bristles, 

 dark palpi, and the costa not thickened in the oiiter part, fmally 

 the female of tarsalis is specially characterized by the foiirth to sixth 

 abdominal tergites being narrow; brevicostalis is known by its less 

 shining frons, this being rather shining in the two other species, by 

 the more distant upper supraantennals and the relatively strong 

 hind tibial bristles.
