tinctly hairy and scaly ; antennce as in Ahantis, but comparatively 
shorter, and with the club rather more abruptly formed and more 
rounded at tip. 
Thorax moderately robust, about as long as abdomen, with rather 
sparse long hair above laterally and posteriorly. Fore-wings with costa 
as in Ahantis ; apex acute but not produced ; hind-margin moderately 
dentate, slightly hollowed just below apex, and again between first 
median nervule and submedian nervure, the intervening space being 
convexly prominent ; posterior angle prominent ; these hind-marginal 
characters more pronounced in the $ ; inner margin concave mesially 
(more so in Pillaana than in Canojpus) ; neuration mainly as in Ahan- 
tis, but disco-cellular nervules less oblique (the lower one considerably 
longer and curved inwardly), and discoidal cell longer. Hind-wings 
rather short, except inner-marginally ; costa short and straight after 
prominent basal lobe ; hind-margin angulated between first and second 
subcostal, and more prominently between second and third median 
nervules ; anal angle moderately lobed ; inner-marginal border clothed 
with long hair ; cilia very long on anal-angular lobe ; neuration as in 
Ahantis. Legs^ with femora all thinly hairy inferiorly ; middle and 
hind tibiee with long sparse hair superiorly ; spur-like appendage on 
fore-tibiiB well developed, as well as second pair of spurs on hind-tibiae. 
Ahdomen shaped as in Ahantis^ but bearing dorsally, on posterior 
part of segments one to three, long, sparsely-set, radiating, erect 
hairs. 
The shape of the wings, which is unlike that of any other South- 
African genus of Hcspcridce, best distinguishes Gaprona from Ahantis, 
and at the same time exhibits considerable resemblance to that found 
in the South-American genus Helias ; indeed, one species of the latter, 
E. Lacoena, Hewits. (as remarked by Mr. Butler in Ent. M. Mag., 1870, 
p. 98), strikingly resembles C. Canojms both in outline and colouring 
of the wings, the pattern also nearly agreeing, except in the smaller 
size of the transparent spots in H. Zaccena. The exceedingly blunt, 
evenly-thick club of the antennje, however, well distinguishes Caproncc 
not only from Helias, but — judging from the figure and description — 
also from the Indian genus Darpcc, Moore,^ in which the dentation of 
the hind-margins is more pronounced. 
The only known species are the type Pillaana, Wallengr., in which 
the ground-colour is greyish-brown with paler markings, and Canopus, 
mihi, which is white with ferruginous and blackish markings, — both 
species bearing also transparent spots. Pillaana is much the rarer, 
being known only by a very few specimens, respectively obtained in 
Natal, Bechuanaland, Damaraland, and Matabeleland ; while Cano- 
pus, with a less extended range (not being known to me to occur in 
^ The fore-coxoe in the S Pillaana (but not in Canopus) have a tuft of long black hairs 
situated and directed exactly as in Ahantis Levuhu, Wallengr.

described as having "the usual second pair of spurs on the hind-tibia) invisible."
