IS DICRORAMPHA SEPARABLE FROM D. CONSORTANA ? 297 
described. However, this phase of the matter is perhaps not of 
particular moment. 
Mr. Barrett considers that Heinemann’s insect is specifically 
distinct from consortana, and this decision would seem to have 
been arrived at after carefully comparing his German types 
of distinctana with a bred series of consortana, which I had the 
honour of submitting to his notice. Although that series of 
consortana consisted of individuals which in some trivial respects 
differed one from another, there were among them specimens 
which possessed the particular character of marking claimed for 
distinctana only. 
I must confess myself unable to decide on the merits of a 
more or less squared wing apex, especially when such comparison 
is made between caught and bred specimens, but I am inclined to 
think that in this particular case such distinctions are un- 
important. 
As regards the pale dorsal mark of distinctana being “ broader 
at the apex, and more strongly divided, each division being again 
divided by a black line,” I can only say that in all the bred 
consortana I sent to Mr. Barrett the dorsal blotch is exactly so 
divided and subdivided, but such division is more distinct in 
some individuals than in others, and it may be that in none 
of them are the divisions so pronounced as in Mr. Barrett’s 
German types. Again, in the majority of the specimens the 
dorsal blotch extends in a slightly oblique direction more than 
halfway across the wing, but in one or two examples this mark is 
distinctly broken at the middle of the wing, and its continuation 
forms a round or nearly round spot just beyond the middle and 
towards the hind margin of the wing. In these last the apex of 
the dorsal blotch may be said to be broad. 
The costal streaks in the bred consortana are usually seven in 
number, and are arranged in the following order :—a pair before 
the middle, another pair on the middle, and three singly at 
regular intervals between the last pair and the apex. In some 
specimens there are an additional pair towards the base, in others 
the pair before the middle are absent, and in one example the single 
streaks only are clearly defined. The ocellus is enclosed between 
the metallic (silvery blue) lines which curve across the wing from 
the third and fifth costal streaks, counting from the apex. I 
may observe that the streaks referred to as occurring in pairs are
