352 THE ULTTKKFJ.IES OF NEW EX(iLANl). 



pressed, very tliin. and luive a beaded appearance from apparent indentations 

 where the cross lines strike them ; these are very faint, scarcely elevated and about 

 .03 mm. apart. The micropyle ])asiu is not depressed but only indicated by the ter- 

 mination of the vertical ril)S and is about .2 mm. in diameter; it is composed (67 : 10) 

 of a central circle, around which radiate eiuht or nine kite-shaped cells, surrounded at 

 tirst by irregular and then by pretty regular pentagonal or liexagonal cells growing 

 constantly larger. Height of egg, .85 mm. 



Caterpillar. First stage (70:28). Head (78:42) shining olivaceous green, piceous 

 by some reflected lights, its appendages concolorous, the hairs black. Body pale green, 

 more or less hoary in the creases, the abdominal segments more or less brownish, 

 especially above. Papillae a darker green than the rest of the body, the hairs black, 

 very long, some being nearly twice as long as the diameter of the body , curving or sinuate, 

 and erect, the curves generally forward or upward. Legs fuscous ; prolegs color of 

 body but apically tipped externally with blackish ; spiracles black. Length, 2.25 mm. ; 

 of longest hair. .1)2 mm. ; breadth of head, .55 mm. 



Second stage. Head (78:43) piceous. Body dark olivaceous green, much iufus- 

 cated. A pale, slender, wavy, substigmatal line, from which on the abdominal seg- 

 ments spring similarly slender, pale, oblique lines, two to a segment, rumiing obliquely 

 backward from each side of the spine; a narrow, subdorsal band made up of transverse 

 pale lines, narrowing posteriorly, and sometimes nearly or quite confluent on the two 

 sides ; a pale annulus around the base of the laterodorsal spines on the thoracic seg- 

 ments, sometimes faintly connected on successive segments by lines running from the 

 upper and lower edges backward. Spines as high as the length of the segments, 

 black, excepting those of the second, fourth and sixth abdominal segments, which are 

 entirely white, including the mamillate base, but excluding the spinules, which are 

 black as elsewhere; apical spinules about as long as the spines, curved, and in the 

 middle someAvhat bent, the others nearly as long as the spines and straight. Legs 

 black; prolegs of the color of tlie body but blackish exteriorly. Length, 5 mm.; 

 breadth of head, .8 mm. 



Third stage. Head (78 : 44). l)ronze-l)laok; most of its high tul)ercles black, but 

 those at back of head and two conspicuous ones at front base of coronal spines 

 white ; most of the hairs are black, but those of the tAvo tubercles just specified are 

 Avhite, as are the apical hairs of coronal spines. Body purplish brown with a greenish 

 tinge, much marked Avith white in short, transA^erse, Avhite streaks in dorsal region, 

 especially about the dorsal and laterodorsal spines ; marked also by an irregular, slender, 

 infrastigraatal line, from Avhich, on the abdominal" segments, arise oblique Avhite 

 lines crossing the segments. Spines and spinules black, excepting those of the dorsal, 

 and laterodorsal series on the second, fourth and sixth abdominal segments, sometimes 

 also the laterodorsal ones of second and third thoracic segments and the infrastig- 

 matal ones of fourth, sixth and ninth abdominal segments, Avhich, but rarely thcii- 

 spinwles, are pellucid AAiiite, occasionally tinged at base Avith orange; sometimes also 

 the slender apical half of the other abdominal tubercles of the dorsal and laterodor- 

 sal spines are Avhite ; spiracles black Avith a pale or Avhite annulus. Length, 8-10 mm. ; 

 breadth of head, 1.4 mm. 



Fourth stage. In this stage the liead (78 ; 45) is as before, Avitii the coronal tubercle 

 larger. In the body the upper surface is divided betAveen an anterior pale, dirty orange 

 held, including the thoracic and two abdominal segments, and a posterior hoary fleld 

 made by heary paraftiue-Avhite nuxrkings, mostly longitudinally disposed, on a black 

 ground. Most of the dorsal, subdorsal and laterodorsal spines and spinules are Avhite, 

 but fuliginous on the third, Hfth, seventh, eighth and ninth abdominal segments, Avhile the 

 bristles ijire ahvays l^lack. The sides of the body are black, marked by a double, chain- 

 like, stigmata! stripe of orange, in the upper line of avIucIi the piceous bases of the 

 suprastigmatal spines are situate. Spiracles black, Avith a luteo-fuscous aureole. 

 Length, 17 mm. ; breadth of head, 1.9 mm. 



Fifth stage (74:32). Head (78:46), black, Avitli a pale, dull luteous W on the front, 

 the middle bars foUoAving the suture of the frontal triangle, the outer terminating at
