This group (Euietnia, lEta, and Taiitiiia) almost directly iutergrade, judging by tlie venation, with the Lithosiida; Byssophaga, Cistheiie, and Crocota conneeting them with Lithosia, though the larva- of the latter are uuich more specialized and Arctiitorni. Hence the line of descent from the generalized Tineiua to the group represented by Eui^mia, OEta, and Tantura to the Lithosiidie and from these to the Arctiidie is more or less is interesting to note the gradual widening of thewings, especially the fore wings, as we pass from Lithosiato Aretia; also to notice the gradual change in thelarval and pup;e characters, those of the Arctiianpup;e being slightly less primitive than in the moregeneralized Lithosiidie. It is also interesting to note that in ascending fromthe Tiueoid precursors of the Lithosiid;e to the mem-bers of the latter familywe pa
