palpi, curving toward one another and connecting ruesially like an X 

 (see this feature represented in the adult head at b, in Figure 17); 

 last joint of the palpi black. Body cylindrical, bearing short black 

 hairs on the setiferous spots, brown, shading darker toward the 

 broad substigmatal yellow-brown stripe, a subdorsal black line 

 shaded with yellow beneath, and a yellowish dorsal line accentuated 

 into yellow spots on the summit of each segment, especially upon 

 the third, fourth, fifth, and sixth (not counting the head as one); 

 on top of the eleventh segment, a v-shaped black patch; beneath pale 

 brown with delicate mottlings. Prolegs pale, semitranslucent. The 

 setiferous spots are elevated and shining black. The larval length 

 at about the end of this stage, is 0.55 inch. 



The distinctive markings of this stage, are the pale lateral stripe, 

 the fuscous dorsum (paler in many examples) and the dorsal line of 

 yellow markings — the anterior ones of which are either rounded or 

 lozenge-shaped and the following ones becoming elongated into lines. 



During this stage and onward to maturity, the brood was fed on 

 plantain leaves (Plantago major), for which they manifested a great 

 fondness. They were not easily disturbed in their feeding when 

 brought under observation. When removed by hand to fresh leaves 

 they simply curled up in the usual cut-worm manner, without showing 

 any alarm. 



Fourth stage. — The third molting commenced on May twenty-first, 

 and was completed in about two days. Their length at the end of the 

 stage was 0.8 inch. The lines of the head are shining black, broader 

 comparatively than before, and yellowish on the sides. Body, general 

 coloring as before; about six conspicuous yellow dorsal spots, a black 

 subdorsal line somewhat broken, with yellow beneath; resting on the 

 line of the spiracles, a broad black band broken into crescents having 

 the spiracles in one tip. The stripe beneath this is greenish with yel- 

 lowish dots and beneath this, over the legs, greenish with whitish 

 dots; a triangular black spot on the top of the eleventh segment and 

 a yellowish patch behind it. 



Fifth stage. — The fourth and last larval molt commenced on the 

 twenty-fifth of May and was completed by the brood, 150 in number, 

 on the twenty-eighth. Of larvse fully matured on the thirtieth, the 

 following are the proininent features: 



Maximum length, 1.6 inch; average length of six examples, 1.46 

 inch, breadth, 0.25 inch. Colors not so bright or so contrasting as 

 in previous stages — the prevailing shade being a sordid brown. The 

 conspicuous features are: The yellow dorsal spots on the hinder part 

 of. segments two to seven inclusive, consisting of three or four trans-
