nervure, form magnamacula. The form with dark rays extending 

 to the base of the wing I call radiis. Usually the first to appear is 

 the one just behind the cubital nervure ; when it is accompanied by 

 one or two others and they broaden so as to blend together they form 

 that large triangular patch which characterises form zonata, Rocci, 

 already described ; as a rule, however, when that triangle is extensive, 

 it is accompanied by other rays and we have what might be called the 

 radiis-zonata form. The two little rays which are inside the cell 

 nearly always fuse with the spot, or spots, at their further end and 

 turn it, or them, into one or two long streaks, just as the rays at. the 

 back of cell fuse with the marginal band ; the red spots N.3, in the 

 cell, and N.4, at the back of it, very rarely subsist and keep the rays 

 separate from these other markings. The next grade in the extent of 

 the dark markings answers to seminigrata, Rocci, described as having 

 red rays at base and two red spots, because the primary dark pattern 

 begins to prevail greatly in extent on the secondary red one; it corres-
