wing mucli paler ; Imid-iving and borders of fore-wing very much paler 
than in $, ^oith an ochreous tinge, and witli the hoary irroration much 
; better developed (especially at and near apex of hind-wing). 
iTliis form is doubtfully separable from L. Cassus (Linn.), the only differ- 
ences of importance being its considerably smaller size, darker colour (especially 
in the 9 ), and the hoary scaling on the under side (particularly apparent at 
j the apices and on the fragmentary rings of the hind-wing ocelli). It is certainly 
scarcer than Cassus, and haunts a different station, being confined, as far as I 
;| know, to the sandy flats in the Cape District and Piketberg. The only example 
jj of several seen which I took at the latter locality was a very dark ^ , which 
I in size and the yellower less hoary under-side scaling showed some approach 
towards Cassus. The only females (two) that I have met with present no trace 
of the small additional ocelli in the fore-wing often found in the 9 Cassus. 
October is its chief month of appearance, but I have taken it in September, 
and (worn) as late as December.

lUAGO.— Head small, tnfted in front ; eyes usually smooth ; paljoi 
rather long, laterally compressed, acute, the basal and middle joints set 
densely and compactly beneath with bristly hairs, the terminal joint 
rather short, acuminate, clothed with very short hairs ; antcnnm rather 
short, gradually but generally very distinctly clubbed. Thorax small 
and short, prominent and hairy dorsally. Fore-ioings rather broad and 
truncate ; costa much arched ; hind-margin slightly convex, very slightly 
sinuated ; costal nervure always, and median and submedian nervures 
usually, swollen at the base ; in the ^ , the last-named nervure often 
has on its lower edge, a little before middle, a small sac enclosing a 
tuft of hair, and the inner margin between base and middle is usually 
convex, while on the under side there is a glossy, sub-iridescent, inner- 
marginal space ; first subcostal nervule originating some way before, 
the second at, extremity of discoidal cell ; where median nervure is 
swollen, its first nervule is given off at extremity of swelling ; cell broad, 
rather short ; middle and lower disco-cellular nervules forming at their 
junction an obtuse angle towards the base, — the lower nervule much 
longer than the middle one. Hind-ivings broad, rounded ; hind-margin 
more or less sinuated ; anal angle often rather pronounced ; costa at 
base slightly excavated, but at a little distance from base strongly pro- 
minent, more or less fringed with short hairs ; in the costal border 
conspicuously glossy and sub- iridescent, with usually a tuft of long hairs
