Monograph of the bombycine moths of North America, including their transformations and origin of the larval markings and armature . /un,> niolina, stage I, tubercles ii are wanting on abdominal segments 1 to 7, thoughpresent on segment 8 behind the caudal horn. This atrophy of // at once clearlj- indicates that. Fig. 1.—Head and first five trunk-seguarrangement o ents ot Sehizurtubercles i-vii. this genus is a later, less primitive form than Adelocephala. a view corroborated by otherchanuters. In Kaden i/), which, generally speaking, has evidently almost directly descended fromAdelocephala, the tubercles ii are absent in all the stages on abdominal segments 1 to 7. Onsegment 8 the tubercles // are situated next to the caudal horn and are of good size in stages I,II, and all the later stages, being about as large as tubercle /// on the side of the segment. In Cltlu-rtmid reijHliii there are no tubeicles ii on abdominal .segments 1 to 7. but they are instages I to V on segment 8. In stage I they are about one-half as large as the caudal horn stages II and III (PI. LIV) they are large and branched, while in the last two stages theybecome reduced, until in the final stage they are about as long as the caudal horn is thick atits base.
