wing much paler ; hind-iving and lordcrs of fore-iving very much paler 

 than in $, with an ochreous tinge, and with the hoary irroration much 

 better developed (especially at and near apex of hind-wing). 



This form is doubtfully separable from L. Cassus (Linn.), the only differ- 

 ences of importance being its considerably smaller size, darker colour (especially 

 in the $ ), and the hoary scaling on the under side (particularly apparent at 

 the apices and on the fragmentary rings of the hind-wing ocelli). It is certainly 

 scarcer than Cassus, and haunts a diiferent station, being confined, as far as I 

 know, to the sandy flats in the Cape District and Piketberg. The only example 

 of several seen which I took at the latter locality was a very dark ^ , which 

 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 $ Cassus. 

 October is its chief month of appearance, but I have taken it in September, 

 and (worn) as late as December,

Imago. — Head small, tufted in front ; eyes usually smooth ; paljyi 

 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 ; antenna) 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-wings 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 ; m the ^, costal border 

 conspicuously glossy and sub- iridescent, with usually a tuft of long hairs
