Westwood had written ^^ Makrena var. absq[ue] fascia in 

 cellula al. ant.," but the fascia here alluded to appears to vary- 

 considerably. The sexing agrees.

[The form Burchelli is at once distinguished from typical 

 jjhenomoe by the greater development of the black markings 

 in general, giving the insect an entirely different aspect, 

 which will be appreciated when figures 1 and 2 on PI. VI. 

 are compared with 3 and 4. The black borders of both wings, 

 including the inner margin of the fore wing, are broader in 

 Burchelli^ as is the black band which obliquely crosses the 

 middle of the cell in the fore wing. But the chief difference 

 is seen in the principal marking, which descends obliquely 

 from the costa of the fore wing across the apical boundary of 

 the cell. This broad black band is, in Burchelli, prolonged 

 beyond the cell in the interspace between the second and third 

 median nervules so far that its total length is about 50 per
