Mr. A. G. Butler on new Sjjecies of Lepido^tera. Vll 



depth of " 1913 " fathoms. Next to Tethea cranium it was 

 the most numerous of all the sponges dredged up on board the 

 ' Porcupine ;' and hence my observations on its extreme pro- 

 lificness (' Annals,' 1876, vol. xviii. p. 405) under the name of 

 Tisiphonia agariciformis^ Wy. Thomson, 1870, = Tethea mu- 

 ricatay Bowerbank, 1858. Perhaps the sessile varieties might 

 be termed " crassa^ Bk." 



XXI. — Descriptions of several new Species of Lepidojptera in 

 the Collection of the British Museum. By Arthur G. 

 Butler, F.L.S. &c. 



Rhopalocera. 



Panopea, Hiibner. 



Panopea expansa^ n. sp. 



Wings above smoky brown with black veins : primaries 

 with a broad central oblique patch (cut into six divisions by 

 the nervures), a subcostal spot halfway between it and apex, 

 below Avhich are two or three longitudinal streaks followed by 

 seven submarginal spots, all subhy aline pearly white ; a bifid 

 internal patch and a spot at apex opaque white : secondai'ies 

 crossed by a broad central band of subhyaline pearly white ; 

 its outer edge dentated through the incursion of the black 

 internervular folds ; a submarginal series of white spots, fol- 

 lowed by a marginal series of orange spots : body black, 

 thorax white-dotted. Primaries below paler, Avhitish at base : 

 secondaries with the base yellowish and marked by seven 

 black spots ; external area pale bronzy brown, with the sub- 

 marginal white spots much larger than above ; no orange 

 spots ; palpi white with black tips ; pectus black, spotted with 

 white; abdomen testaceous. Expanse of wings 3 inches 

 1 line. 



Masasi, East Africa. 



This species is most nearly allied to P. protracta ; but the 

 broad patch or band of primaries renders it a link between 

 that group and P. mima ; the marginal orange spots of the 

 secondaries are peculiar. 



Neptis, Fabricius. 

 Neptis trigonophora^ n. sp. 

 Allied to N. melicerta, but with the broad bifid discoidal
