into rings inclosiiif-- wliitisli si)ace.s. Four straw-yellow dorsal bands, varyinji from whitish 

 to straw-yellow, and iiiclosiufj three narrow, broken choeolate lines. Below the broad lateral 

 clioeolate band are two whitish yellow irregular lines, one. just above and the other Just beneath 

 the spiracles. Underside of the body with the abdominal legs pale livid-gray. On the outside 

 of the abdominal legs above the plauta is a dark ehoeolate In-own i>atch. Suranal plate dark 

 chocolate brown. The hairs are sparse and pale gray, uneven in length; the lew longest ones 

 arise from the thoracic segments and from the eighth to ninth abdominal segments. The piliferous 

 warts are yellow on the yellow ground and brown on the brown portions of the skin. On the 

 eighth abdominal segment are two yellow i)iliferous tubercles situated on the brown skin. 



It molted June 22. 



It seems to l)e like the Eastern apicalis (van) in Stage III. 



Stafic III. — Length, 15 mm. Head cliitiuous brown, mottled with close set dark spots. 

 Prothoracic shield divided into two parts by a pale median space. In general as in Stage II, 

 liiii the four pale dorsal lines are ichiter than before, becoming straw-yellow around the bases 

 of the yellow [)iliferous warts. The brown lines and lateral band and the brown swollen first and 

 eighth abdominal segments are as before. Hairs long whitish. On the brown bands and segments 

 the piliferous warts are pale, not prominent. 



The larvie have now sewed together two leaves and live between them much as does 

 I. inelnsa. 



The larvffi molted into the last stage June 28 to July 12. 



The larva when of this stage is more like I. inelusa when about l-") mm. long than the iully 

 grown Eastern apicalis (rau), though in /. iuchtsa the eighth abdominal segment is not blown, 

 according to Bridgham's ligure, and is somewhat as is albosigmu in its thiid stage. 



Last staije. — Length, 30 mm. Body thick and fulL Head uot so wide as the body by a fifth; 

 pale yellowish brown or chitin colored, (vith darker flecks; it is much flattened in front, the 

 clyi)ens Hat and sunken. Jaws and ocelli lilackish, contrasting with the light-colored head. 

 Body of a peculiar light yellowish sienna brown, with a grayish tinge. Skin somewhat rough, 

 with fine minute warts giving rise to fine close-set pale gray hairs of uneipial length. On the 

 prothoracic segment are two dusky dorsal flattened low warts elongated transversely, the 

 corresponding ones on the succeeding segments being bright yellowish brown, each giving rise to 

 one or two long thick pale hairs. A lateral yellowish brown wart in front of the i)rothoracic 

 siiiracles. On the second thoracic segment are three yellowish l)rown warts on each side, forming 

 a transversely straight line of six warts crossing the segment. On the third thoracic segment is 

 a transverse row of eight similar warts, the additional ones being one Just above the base of 

 each leg of the third i)air; corres])onding warts are ])resent on the prothoracic segment. No 

 trace of a hump or of any other distinctive mark on tlir jirst or eighth abdominal segments, but in 

 place of them are two small yellon-ish brown warts, situated Just in front of the line of six warts 

 common to all the abdominal segments, though there are two similar but much smaller, nearly 

 obsolete, warts which occur in the same ]>osition as on the other alxhuninal segments, those on 

 the second abdominal segment being the most distinct. Three faint broken jiarallel dorsal lines 

 and a faint lateral sjjiracular band, above and below which is a faint whitish line. The skin is 

 covered with somewhat irregular continent colorless spots of irregular shape. All the legs are of 

 the same color as the body.

The single type differs from Mr. Edward.s's tyi)e of brueci in the oblique silver-white costal 

 streak being more sinuous, as is also the line across the wing which forms the continuation of the 

 streak. On the other hand, the other (inner) arm of the V is straight, not sinuous, the inner two 

 lines about the same. The submarginal spots and streaks are the same in both species.
