areas a little more finely striate; dorsal and ventrat 

 areas with margins striated, disks r«^arly smooth in 

 adult larvae, last segment more strongly striate, especially 

 beneath. 



Dark annuli distinct, broad, including false feet, a dis- 

 tinct transverse dorsal and ventral pale spot in front of 

 the false feet; abdominal annuli often with a small tri- 

 angular backward prolongation on median line above. 

 Prothoracic lateral space occupied by a pale brownish 

 fuscous quadrate spot in front of the striated space. 

 Meso- and metathoracic lateral stripes usually distinct, 

 but slender, scarcely dilated posteriorly, lateral edges of 

 dorsal areas diverging; lateral stripes of abdomen al- 

 most w^anting, except on last two or three segments. 

 In these stripes the punctures of the upper and lower 

 rows are indicated by rounded pale dots, and those of 

 the inner rows by elongate dots. Last segment with 

 bases of respiratory tube and anal prominence encircled 

 with dark rings, joined by a lateral connection, its dorsum 

 with at most a short basal line or pair of dots on each 

 side. Coarser pubescence of false feet tipped with palfr 

 brownish. 



Main internal tracheae thick and noticeable, especially 

 in young larvae, lustrous, subparallel. not strongly sin- 

 uate, nearly straight posteriorly; terminal stigmata! 

 spine dark reddish brown, smooth, usually protruded.

Pupa, V. — Length about 30 mm., diameter about 6 mm. 

 Light brownish fuscous, thorax paler, shining, abdomen 

 roughly transversely wrinkled, and subopaque. Palpal 

 sheaths distinct, as far apart as are the setae borne by 

 the larger tubercles at the center of the anterior sui-face 

 of the head; surface between them rounded, bearing a 

 small wrinkled tubercle at middle; antennae and tubercles 

 darker than surrounding surface; ocellar tubercles dis- 

 tinct; prothoracic spiracular tubercles slightly but evenly 

 elevated in a plane parallel to that of the surrounding sur-
