PALKACRITA VERNATA. 



Head distinctly mottled and spotted, 

 the top pale, and two pale transverse lines 

 in front. 



Body with eight superior, narrow, pale, 

 lontjitudinal lines barely discernible, the 

 two lowermost much farther apart than 

 the others. 



Dorsum pale, with median black spots ; 

 subdorsal region dark; stigmatal region 

 ■quite pale. 



Pillit'crous spots quite visible and large 

 on joint 11, where the pale lines generally 

 enlarge into white spots immediately in 

 front of them. 



AVhen newly hatched dark olive-green 

 or brown, with black shiny head and cer- 

 vical shield. 



Chr 



Formed in a simple earthen cell, the 

 earth compressed, and lined with very 

 few silken threads so as to form a frrigile 

 •cocoon, which ea«ily breaks to pieces. 



ANISOPTERYX POMETARIA. 



Head very indistinctly spotted, and dark 

 on top. 



Only six superior, broad, and very dis- 

 tinct pale lines, those each side equidis- 

 tant. 



Dorsum dark, without ornament ; sub- 

 dorsal region pale ; stigmatal region dark. 



Pilliferous spots subobsolete. 



When newly hatched jiaAe olive-green, 

 with very pale head and cervical shield. 



•y&alis. 



Formed in a perfect cocoon of fine, 

 densely spun silk of a buff color, inter- 

 woven on the outside with particles of 

 earth ; never breaking open except by 

 force or purpose. 



Male — Sparsely and shallowly pitted. 

 Pale grayish-brown, with a greenish tint 

 on the wing-sheaths, which extend to the 

 posterior edge of the 5th abdominal joint; 

 abdomen with the spine at tip gneerally 

 simple, and only occasionally slightly 

 bifurcate. 



Female — With wing-sheaths, but com- 

 pared with those of the male, thinner 

 and extending only to the posterior edge 

 of the 4th abdoaiinal joint: much more 

 robust and more arched dorsally, with 

 the mesothoraeic joint shorter, and much 

 reduced in .size. Pitted like the male. 

 (Fig. 5.) 



Male— Not pitted. Darker brown than 

 vernata; the wing sheaths, as in vernata^ 

 reaching to the 6th abdominal joint; the 

 anus more blunt and with the spine more 

 dorsal, decurved, and always bifurcate, 

 the prongs spreading and often long and 

 fine. (Fig. G, a.) 



Female— Differs from the male in the 

 same way as vernata, but is relatively 

 stouter and more arched dorsally : a 

 broad, dusky, dorsal stripe often visible 

 toward the time of issuing — all the more 

 remarkable that there is no such stripe 

 on the imago, whereas in vernata^ where 

 the imago has such a stripe, it is not indi- 

 cated in the chrysalis. (Fig. G, b.)
