This species and the next one belong to a group closely 

 allied to the preceding one, the abdomen being largely 

 yellowish pellucid with similar black marks, but both have 

 the thorax with conspicuous black marks and the eyes of the 

 male are more widely separated, the frons being distinctly 

 wider than the width of the third antennal segment. The 

 postsutural transverse black fascia on thorax in Incida is 

 entire, while in the next species it is more or less distinctly 

 interrupted on each side of the median line, the fascia
