94. Agorea semivitrea nom. nov. 



This is the insect which has been hitherto identified as the Phalaena pdlacidu, 

 of Sepp, though the presence of the black discoidal stigma and the line of black 

 sjiots on abdomen being confined to the basal and apical segments in most specimens 

 ought to have prevented this error. I have two specimens of an insect from 

 Surinam which agree exactly with Sepp's figures, but it is a Bitunjx and not 

 an Aqorea. Therefore Sepp's insect must in future stand as Bitiiryx pellacida 

 (Sepp).
