DESCRIPTIONS OF NEW SATUBNIIBAE. 



By k. Jordan, Pn.i). 



1. Rothschildia amoena spec. nov. 



c? ?. Near li.jorulloides Dogn. (1895) and maurus Bnrm. (1880) ; abdomen as 

 in those species without white line on npperside. Both wings shorter and broadc r 

 than in the allied sjiecies. The discal line dentate as in R. jorulloidcs, that of the 

 forewing both in the new species andjorulloirh's being less dentate from the vitreous 

 patch to the costa thau in maurus, and in the new species more curved basad 

 anteriorly and posteriorly than even in jorulloidcs ; the band accompanying the white 

 discal line is grey, there being only a narrow reddish line alongside the white one. 

 The white oblique subapical line SO'' — K' of the forewing shorter than in the allied 

 species, presumably owing to the less produced apex of the wing, median branches 

 huffish in the central area ; vitreous sjiot triangular, all three sides distinctly 

 incurved, the costal side least, the black border of the spot distinct ; marginal area 

 of both wings similarly marked and coloured as in jorulloidcs. Vitreous spot of 

 hindwing with the black border more distinct than in the allied species, anterior 

 and posterior sides slightly incurved, proximal side incurved in cJ, convex iu ?, 

 veins slightly buff; the central area bounded by the antemedian and discal lines 

 broader than the outer area from the discal line to the margin, the measurements 

 from the antemedian line across the tip of the vitreous patch to the apex of the 

 second radial vein being : central area 20 mm. and outer area 17 mm. 



These distinctions are repeated on the underside. 



lliijj. Matucana and Surco, Oroya railway, 70(tO to SOUO ft.. West Pern. 



The Rev. A. Miles Moss bred a number of specimens of this insect. The 

 description and figure of the larva will be given in another place. 



2. Rothschildia maurus lutea subsp. nov. 



?. The entire insect clay-colour as regards the ground. The discal line less 

 dentate than in A', m. maurus, on the forewing anteriorly hardly at all dentate and 

 here distinctly curved basad, the extreme tij), however, as in maurus, pointing 

 obliquely distad ; grey scaling outside discal line more extended on both wings 

 and much more produced distad at the veins ; the vitreous patch of both wings 

 extended into the discal line, on the forewing its proximal edge anteriorly slightly 

 incurved and then convex, on the hindwing irregularly ovate, as in specimens of 

 maurus with exceptionally large vitreous patches ; the black border of the lines 

 and vitreous spots more distinct than in m. maurus, owing to the pale ground- 

 colour ; the outer border of the white discal line very slightlj pinkish, less so than 

 in m. maurus. 



On underside duller and paler than on upper, the ground being olivaceous 

 cinnamon iu the basal half and butfish wood-brown in the outer area. 



Length of forewing : 75 mm. 



Jla/j. Sapucay, near Villa Ilica, Paraguay, January 21, 1905 (W. Foster) ; 1 9. 



Another ?, from Juudiahy, near liio de Janeiro {h\ Dittrich), closely agrees 

 with the preceding except iu being much smaller (length of forewing Go mm.) and
