from tlie cervical shield and the anterior 

 edge of the prothoracic segment to the 

 anal plate and becoming a little con- 

 fluent there. Cervical shield, anal 

 plate, thoracic and anal feet and the 

 abdominal feet outwardlv black. Hair 

 short anil pale. During this stage, the 

 larvae eat the whole leaf. 



Third stage. He-ad higher than 

 witle, depressed at the sutures of the 

 clvpeus ; smooth shinv black, width 

 1. 8 mm. Body brown, the stripes yel- 

 low, confluent posteriorlv and along the 

 anterior edge of the prothoracic seg- 

 ment. Otherwise as in the previous 

 stage. 



Fourth stage. Head shaped as be- 

 fore, smooth ; centrallv dej^ressed at the 

 top of the clvpeus and more slightly 

 along the central suture ; clvpeus and 

 labrum wrinkled ; all shining black ; 

 width 3.3 mm. Cervical shield black 

 or partly brown, in some examples 

 nearly all light brown ; anal plate, 

 thoracic feet and the abdominal feet 

 outwardlv, black. Body black or partly 

 brown, the anterior lialf of the pro- 

 thoracic segment vellow. the stripes 

 stronglv confluent on the last segment. 

 The bases of the legs and corresponding 

 spots on the legless segments, as in the 

 mature larva, of a darker vellow than 

 the lines. Each segment is shaded cen- 

 trallv with this yellow, but it does not 

 cause the lines to appear confluent on 

 account of its darker shade. Hair sor- 

 did white beside other short fine brown- 

 ish hair seen with a lens. 



Fifth stage. Head as high as wide, 

 flattened in front, depressed at the upper 

 part of the sutures of the clvpeus, punc- 



tured. Clvpeus and labrum somewhat 

 wrinkled. Color shiny black, the an- 

 tennae and palpi white-ringed, their bases 

 greenish. Width 5.4 mm. Body black, 

 cervical shield honey yellow, anal plate, 

 thoracic and anal feet and the abdomi- 

 nal feet outwardly, black. Anterior half 

 of the prothoracic segment yellow ; 

 stripes narrower than the spaces, citron 

 yellow, running into the yellow part of 

 the prothoracic segment and confluent 

 posteriorly on the tenth abdominal, 

 which is all vellow except the anal 

 plate and a dorsal band. The three 

 upper lateral lines are connected also on 

 the eighth and ninth abdominal seg- 

 ments by a broad dark yellow shade. 

 The bases of the legs and corresponding 

 spots on the apodous segments (on the 

 first, second, and seventli. eighth and 

 ninth abdominal segments) also dark 

 yellow, forming expansions of the sub- 

 ventral line and reaching the lowest 

 lateral line, except on the thoracic seg- 

 ments and the ninth abdominal. On 

 the apodous segments in the centre of 

 each yellow patch, is a small black spot, 

 representing the absent legs, but this 

 is not present in all examples. Hair 

 rather abundant, sordid white, the long 

 and short hairs concolorous, arising from 

 minute blackish tubercles which, in the 

 black parts of the body, are each sur- 

 rounded by a minute yellow ring. 



Pupa. Exactly like thatof /?. major ; 

 the two cremasters each bear three spines 

 in a transverse row, the posterior one 

 the longest. Length 28 mm ; width 10 

 mm. 



Single brooded, the winter being 

 passed in the pupa state beneath the
