carpia Kotschy, /. c.) abortu sæpius tres, scutellis dorsalibus oblongo-suborbicularibus, albidis, quoad 
structuram supra descriptis, 3—4 lin. longis, juxta margines laxe inter se cohærentibus abscondita, 
quoad fabricam internam iis speciei sequentis omnino similes, et descriptioni atque iconi speciei
