WERNER MARCHAND 175 



vided by longitudinal grooves into four nearly equal parts, which may be called 

 the dorsal, ventral, and lateral areas. The lateral areas are shining and finely 

 striated on the posterior third and opaque on the anterior two-thirds; the dorsal 

 and ventral areas are opaque on about the anterior fourth and distinctly shining 

 on the remaining parts. The ventral space is plainly divided into two equal parts 

 by a longitudinal groove. In order to see the character of this segment, it must 

 be fully extended. The mesothoracic and metathoracic segments have a num- 

 ber of longitudinal grooves, some of which are very narrowly bordered by opaque 

 darker coloring, which proceeds backward from the narrow anterior border of 

 these segments. Each of the first seven abdominal segments has on its anterior 

 part a transverse row of eight tubercles which encircles the segment. These all 

 bear short spines or claws at the apex, excepting a dorsal pair on each of the first 

 three or four segments. They may be called prolegs, since they have the parts 

 necessary to such organs and, what is more, are used as prolegs. On the poste- 

 rior dorsal border of most of the abdominal segments there may be a narrow, 

 irregular, opaque marking of the same color of the narrow band in the region of 

 the prolegs; eighth segment on each side with two narrow, curved markings which 

 have the appearance of being composed of contiguous punctures. These mark- 

 ings are of the same shade of color as the other darker areas, and the lower one 

 is more than twice as long as the upper." 



"Pupa. — [Plate 11, Fig. 128.] 18 mm. long and 4 mm. in diameter. Light 

 brown in color, thorax somewhat paler than the abdomen. Antennal and other 

 tubercles of the head and thorax prominent and darker than the surrounding 

 parts. Prothoracic spiracular tubercle slightly elevated, reniform, oblique; rima 

 uniformly curved for nearly its whole length; but just before the anterior end the 

 curvature is stronger, although no hook is formed. First abdominal spiracle 

 nearly round; rima almost uniformly curved, posteriorly very slightly widened 

 just at the end, anteriorly slightly narrowed and curved so as to form a short 

 hook. The other abdominal spiracles agree with the first one in general, but 

 there is slight variation in the enlargement and curvature of the extreme ends. 

 Terminal teeth [Plate 13, Fig. 160] prominent, shining brown in color, darkest 

 at the extreme tips. Dorsal pair of teeth smallest and closer together than 

 the ventral, lateral teeth longer and larger than the ventral and located much 

 beneath the dorsal, in fact they are nearly midway between the dorsal and 

 ventral."
