thickened with dense scales, posterior tibiae clothed with dense 

 long hairs. Fore-wings with 12 veins; no secondary cell ; 1 

 strongly furcate at base ; 7 and 8 long-stalked, going to either 

 side of apex. Hind- wings with 8 veins ; 2 and 4 from posterior 

 angle of cell. 



The genus may be recognised by the very unusually broad 

 wings, the crested thorax, and amongst those nearest to it by the 

 stalking of veins 7 and 8 of fore-wings. In shape of wing it 

 resembles Simaethis, but surpasses it in breadth ; in the palpi, 

 and black hind-marginal spots it has affinity with EapseUa and 

 Aeolocosma. The only species at present known is brilliantly 

 marked ; it flies in the hot sunshine with rapidity, and is then 

 difficult to see ; in repose the wings form a broad nearly flat roof, 

 and are not raised as in Simaethis. 



Hyp. thesaurella, n. sp. 



(^ ? . 7V'-8". Head, palpi, and thorax dark fuscous, densely 

 and irregularly mixed with ochreous and pale scales. Antennae 

 of (^ ochreous-f uscous, of ? ochreous annulated with dark fuscous. 

 Abdomen dark fuscous, lateral margins yellow. Legs dark 

 fuscous, indistinctly ringed with ochreous ; posterior tibiae yellow. 

 Fore-wings black, basal half almost entirely occupied by four 

 transverse, rather outwardly curved, almost confluent faint 

 ochreous-whitish bands, composed of numerous very fine transverse 

 strigulae, these bands being very obscurely separated by slender 

 black lines, only distinct as black spots on costa, where also the 

 pale bands are usually more distinct ; a small ochreous-whitish 

 spot on costa in middle, giving rise to an indistinct orange-ochreous 

 transverse line marking off the basal half, and itself immediately 

 followed by a metallic bluish-purple line of raised scales ; 

 immediately preceding the ochreous line are three small metallic 

 bluish-purple raised spots, one on inner-margin, one above and 

 one below middle ; and at about ^ from base is a transverse 

 metallic blue raised line from middle of disc perpendicularly to
