band, edged and shaded with white. The blotches around th-e spiracles 

 are more distinct — the spiracles themselves are black in the centre, 

 with a clear white spot above and below. The underside has a crim- 

 son line along the anterior and posterior portion, and sometimes a 

 crimson transverse line in the middle between the abdom. legs and 

 thoracic feet. 



Pupa. Pitchy brown, elongate, head parts much produced, and 

 flattened about the wing cases. The segments are roughened on the 

 anterior, rather smooth on the posterior portion. Cremaster rough, 

 thick, and long. 



Length, 1.50 inch. 



Two specim'ens of the larva have the 2d segment somewhat raised, 

 roughened, with small tubercles, reddish orange. T^e spiracles are 

 bright crimson, surrounded with a crimson ring or blotch. Caudal 

 horn also crimson. 



Darapsa choerilus. Cram. (No. 70.) 

 Larva. (Full grown.) 



Head very small, as in all the genus, pale yellow green, with darker 

 median line; 2d segment, yellow green, with numerous irrorations. The 

 spiracles in this segment are all orange in centre, pale yellow above and 

 below. In the other segments they are orange, white above and below. 

 Segments 3, 4, and 5 are also pale yellow green — the two latter swollen 

 into a hump. The remaining segments are all bluish green, covered 

 with white dots, and with a slightly darker dorsal line. On 5, 6, 7 and 

 8 are oblique whitish bands; but on the posterior segments these are 

 lost in a continuous line to the base of the caudal horn, which is bluish 

 at the base, pale green at the tip, and white in the centre. The anal 

 segment is yellow green, as also are the abdominal legs. The thoracic 

 feet are green, with the sides orange red. 



Previous to change, the caterpillar assumes a purplish leaden hue, 

 the dorsal and lateral lines becoming blackish. 



One specimen is pinkish, with the 4 anterior and the anal segment 

 of a brownish cast, and with a dark dorsal stripe. The lateral line is 

 also brown. 



The differences between D. Myron and D. Choerilus are that in the 

 former the whitish oblique stripes are interrupted by the lateral line, 

 which forms a straight edge at the junction of the oblique lines. There 

 is also a distinct white lateral line along the anterior segments, 2, 3, 4, 

 and 5, which is wholly wanting in D. Choerilus. D. Myron has also a 

 row of sub-ovate dorsal spots on the anterior portion of each segment. 

 The color of Z). J/)'r(?// varies exceedingly, green, cream-color, purplish 

 brown, deep brown and lead color being found. 



Food plants. , Viburnum opulus. V. dentatum. 



Pupa. Purplish brown, with pink tint over the whole surface, 

 slightly mottled. Wing cases also mottled with black. Spaces between 

 the segments pitchy brown. Spiracles large, well marked, deep brown.
