Mr. A. G. Butler on the Genus Azelina. 41 
36. Azelina minima, sp. n. 
Allied to the preceding species, but with the general aspect 
of A. clysiaria. Primaries with trisinuate outer margin ; 
dark sericeous brownish grey irrorated with black; costal 
border mottled with whitish; a rather broad irregular central 
ferruginous band bounded by the ordinary lines, which are 
blackish and subparallel to the subcostal vein, where the inner 
line turns inwards at an acute angle, which emits a spur 
downwards to the end of the cell, and is followed by a small 
ochreous spot bounded externally by a pure white crescent ; 
fringe varied with cupreous: secondaries with an acute angle 
at the extremity of the second median branch; slightly paler 
brownish grey than the primaries, but transversely mottled 
with slightly darker grey ; discal line indistinct, paler than 
the ground-colour; submedian vein streaked with reddish 
cupreous in the centre ; an incomplete submarginal series of 
black dots: thorax olivaceous brown ; abdomen pale brownish 
grey. Primaries below sericeous, grey, slightly silvery to- 
wards the inner and outer margins; costal area whity brown, 
striated with darker brown; an indistinct wavy abbreviated 
discal line from the costa; postdiscal white crescent as 
above; fringe whitish at the base; secondaries pale cupreous, 
brown striated with grey, the abdominal border white; a 
diffused grey discal belt, beyond which the external area is 
whitish: body below greyish; legs cream-coloured. Ex- 
panse of wings 1 inch 2 lines.

Our example does not quite agree,with Cramer’s figure; so 
that it is just possible that the Surinam form may be distinct. 
Without specimens from both localities, however, it would be 
rash to separate them.
