N.B. — This is essentially a variable species both in size and 

 in wing markings, the Indian Museum series ranging from 7 

 to 12 millimetres in length, all the specimens hailing from Nepal. 

 In the same collection is Bigot's type of his octonotata (a nomen 

 nudum) which is, I feel convinced, only a varietal form of insulata. 

 In it the eight spots referred to are, presumably, (i) a distinct 

 oval spot on the tip of the 2nd vein, (2) on the base of the fork 

 of the 3rd and (3) at the junction of the veinlet joining this to the 

 2nd, (4) two small contiguous round ones (probably counted 

 as one spot only) occupying the cross-vein between the 4th vein 

 and its adjacent branch, one each at (5) the base of the lower 

 fork of the 4th vein, (6) the cross-vein uniting this to the 5th vein, 

 and (7) one on the base of the intermediate branch of the 4th vein, 

 finally (8) a dark but distinct spot-like suffusion spread over the 

 discal transverse vein and base of the 2nd vein, thus, on the dark 

 part of the wing but much darker. Moreover the ist posterior 

 cell is closed distinctly before the border. This specimen is from 

 Dehra Dun (foot of the Mussoorie hills). A second specimen 

 of this variety (from Calcutta) shows the ist posterior cell closed 

 almost on the border. 



What I take to be the typical form of insulata is shown in 

 plate xii, fig. 21, and in this the brown colour of the wings extends 

 further posteriorly and is darker, thus obliterating what I call 

 Bigot's 3rd spot, but which can usually be perceived if examined 

 closely, and which is invariably present in individuals where 

 the brown colour of the wing is less extensive. The same remark 

 applies to the dark spot over the discal transverse vein, which 

 can invariably be discerned, being distinctly darker than the 

 brown colour which, nevertheless, always entirely surrounds it. 

 A principal difference between typical insulata and octonotata is 

 the presence of two very small spots on the fork of the 3rd vein, 

 also the spot that I call Bigot's 4th is much Isrger, more irregu- 

 lar, and takes the form either of a single irregularly shaped spot, 

 two contiguous spots or three contiguous and merged spots. My 

 6th, 7th and 8th spots of Bigot are generally more enclosed by 

 the brown colour. In nearly all the typical S2:)ecimens there is 

 a foreshortening of the branches of the 4th vein, or appendices 

 to one or more of them, all tending to prove the considerable range 

 through which this species may vary.
