slightly more shaded with fuscous, in the vitreous spots beiug shorter (although 

 they invade the discal line), and the one on the forewiug having the proximal side 

 distinctly incurved. 



The specimens recall by their luteons coloration B. arcthusa Walk. (1855), 

 which we know from Eastern Brazil, Paraguay, and the t'haco of Argentina, and as 

 a special race from the middle Amazons. 



o. Rothschildia arethusa rhodina suhsji. nov. 



cJ ?. Differs from li. a. arelluim Walk. (Is.Jo) in the discal line of the forewing 

 being more deeply incurved between costa and vitreous patch, and in the white and 

 brown scaling between the discal line and the margin being more extended on both 

 wings above as well as beneath. Moreover, the hindwing is, between the apex and 

 lower radial vein, distinctly incurved in the S and only feebly rounded in the ? . 



Hob. Obidos, Amazons, July— August 19i)T (F. Santos) : one pair. 



While in R. tmuirus the black spot below the apex of the forewing is large 

 and is accompanied by two small narrow spots, usually joined together so as to 

 form a half-moou, the black spot is small, triangular, acutely pointed in 1{. arethusa, 

 and is accompanied by two spots which are black shaded with buff and are larger 

 than the black triangle, being about the size of the buff submarginal spots below 

 them. 



4. Samia lunula fulva sulisp. nov. 



c??. A most remarkable race of S. Ininila Walk. (IS.').'!). Body and witgs 

 dark tawny-ochraceous. Collar and legs without white, with the exception of 

 the inside of the femora and a minute tuft at the knee-joints. Abdomen with 

 well-separated rows of small greyish white tufts as in -S'. ci/uthia Drury (1773). 



Wings, uppersidc. Antemedian line of forewing more or less shaded with 

 black, sharply edged with black both on the proximal and distal sides, continued 

 along the median nervules to discal line ; the latter purer white than the ante- 

 median one, narrow, sharply defined, on the whole thinner than its sharply-deficed 

 black proximal border ; at outside of the discal line a narrow fuscous band, slightly 

 tinged with pink and not bearing a pink or fuscous line as in 6'. lunula ; disc 

 tawny-ochraceous, irrorated with fuscous ; costal area shaded with grey and i)ink 

 between discal line and apex ; the submarginal line separates a yellowish buff band 

 from the more or less olivaceous margin ; discocellular half-moou as in S. lunula, 



except that its black anterior edge is more jirominent. The same differences 



obtain in the hindwing, with the exception of the discal shadowy band which 

 borders the discal line bearing a vestigial pinkish fuscous line. 



L'ndertside duller than upper, being less bright ochraceous-tawny ; discal band 

 with a more or less distinct pinkish line, which is best develo2)ed on the hindwing. 



Length of forewing : 08 to 7U mm.

■"). Actias selene callandra subsp. nov. 

 c?. Body and wings uniformly maize-yellow. Eye-sjiots smaller than in 

 A. s. selene Hubn. (ISUO ?), the i)art outside the transparent discocellular bar paler 

 yellow than the wing, the jiroximal dark lialf-moou bordered with pink at the 

 transj)arent bar. Subbasal and discal lines blackish olive, sharply marked, a second 

 discal line sometimes faintly indicated. Lines uf hindwing also blackish olive, less
