have discovered his error, and to have shifted the name Ahrochia 

 to my new genus Sphecosoma. 



Genus SpnECosoMA, u. gen. 



Abrochia (part), Herrich-Schaff'er. 



This is, I believe, the Ahrochia of the ' Correspondeuz-Blatt,' 

 but not of the ' Aussereuropiiische Schmetterlinge ;' it closely 

 resembles Pseudospliex, but differs from it in the simple ISuchro- 

 mioid newxdiXioVi of the secondaries. Type, S.fasciolata, n. sp. 



1. Sphecosoma fasciolatum, n. sp. 



Body sulphur-yellow ; frons white, with a central grey spot ; a trans- 

 verse line or crest and another at back of head black ; antennae with 

 basal half blackish, apical half orange, apex blackish ; palpi golden 

 yellow ; collar with a black band behind ; pterygodes margined with 

 black ; thorax with a black central longitudinal line and a streak on 

 each side of it close to the pterygodes, a transverse line at back of 

 thorax and the inner edges of the glandular drums black ; all the seg- 

 ments banded with black, first segment with three longitudinal black 

 lines ; wings whitish hyaline, veins and outer margin slenderly black ; 

 costal and interno-basal areoles of primaries orange ; body below 

 pale sulphur-yellow; legs orange, femora and tibite with a black 

 streak above ; abdomen with an apparently pale cream-coloured wax- 

 like sheath over basal segments, edged behind with black : expanse 

 of wings 25 millims.

Genus Loxophlebia, u. gen. PL XXVII. fig. 14. 



Allied to the preceding genus, but larger, the outer margin of 

 the primaries much longer, the discocellulars forming an oblique 

 line; the secondaries less than half the length of the primaries, 

 the abdomen very slightly contracted at the base.
