The absence of yellow-ochreous colouring at once serves to distinguish this 
dingy Lycsenide from A. Protumnus (Linn.), and tends to approximate it to 
A. hasuta, Walgrn. From the latter, as far as the ^ is concerned, A. hrachy- 
cera may be known by its darker colouring, larger and more pronounced spots, 
and want of whitish on disc ; while on the under side it is considerably darker, 
has the fore-wing spots much larger (with the marked exception of the spot 
near base below cell), and the discal row of hind-wing much broader and more 
regular. The 9 is readily recognised by wanting the conspicuous white discal 
markings of the ? A. hasuta on the upper side. Apart from pattern and 
colouring, however, A. hrachycera exhibits a remarkable structural distinction 
in the extreme shortness of the antennae. This is noticeable in both sexes, but 
especially in the 9 > whose antennae are only about 2 J lines in length, — shorter 
than in Protumnus, and much shorter than in Basuta. 
The variety noted seems to be very rare. I have only met with three exam- 
ples, all near Cape Town ; and a fourth, in the collection of the South African 
Museum, was, I believe, captured by Mr. E. L. Layard in the same locality. It 
is, however, such a small obscure insect, that it would very readily escape notice. 
Two specimens I took occurred at a considerable elevation on the southern spur 
of Table Mountain, and the third at the base of the mountain itself. 
With the exception of these specimens of the variety, all the BracJiycera I 
have seen were taken at Knysna. Like Protumnus, they were strictly summer 
butterflies, appearing between the end of November and beginning of February. 
They settle on the bare ground, and I used often to find them sitting on the 
heaped-up dust of the waggon-roads, to which they would return after being 
roused by the passing passenger or vehicle. Their flight is weak and very 
short.
