isolated. Cervical plate large, concolorous with head or somewhat 

 paler, with a pair of medio-lateral spots and dark prominent setae; 

 cicatrices on pedal segments prominent, black, of the same size as the 

 spiracles. 



Instar VIII. — Head clear pale yellow, faintly clouded with dark, 

 occllar area black, caudal margin of head black beginning at a black 

 spot on margin of gense; set« on face pale brown, arising from minute 

 clear, brown-edged circles. Cervical plate large, pale, concolorous 

 u'ith head or paler, with small brownish spot near lateral extremity 

 and a group of dots on each side of median line near caudal margin, 

 median line pale. Kappa almost directly dorsad of eta on the abdomi- 

 nal segments. In live specimens the pinacula have their outlines 

 obscured by the reddish stripes which cross them. These stripes 

 appear first in II and III and become more pronounced until in the 

 older larvae they give the color to the whole body. They run as 

 follows : a narrow medio-dorsal line, a wider one on each side of this and 

 separated from it by a narrow broken whitish stripe runs through the 

 outer half of pinacula alpha and includes beta, between this and rho 

 runs another white line similar to that dorsad of alpha below which the 

 spots and body are various shades of suffused red, pink and salmon. 

 The larva as a whole appears of a bright brick-red color. In alcohol the 

 red striping disappears. 



Pupa (Fig. 5) — Length 9 mm., width 2.7 mm. Of the usual pyralid 

 shape, yellowish brown, the sutures marked by narrow maroon lines. 

 Epicranial suture obsolete; fronto-clypeal suture present only at margin, 

 running a short distance meso-ventrad from the ventral comer of the 

 antenn£e; front with a large, dark, flattened and somewhat depressed 

 tubercle inesad on ventral margin and a small dark point mesad near 

 caudal margin of clypeus; maxillae almost equaling wings; tarsi of 

 ]jrothoracic legs ending about two-thirds of the distance from vertex 

 to caudal margin of wings; antennae extending about half wa}' from the 

 tips of the mesothoracic tarsi to the caudal margin of the wings; pro- 

 thorax large, strongly convex cephalad, caudal margin straight and 

 OTily slightly elevated and wrinkled laterad for the prothoracic spiracles ; 

 mesothoracic wings extending to caudal margin of fourth abdominal 

 segment; cremaster short blunt, rounded or feebly angled distad, 

 above sloping with two minute attenuate spines at the angles and with 

 a short deep curved furrow on each side running from the base cephalad, 

 laterad and ventrad finally becoming obsolete on the lateral line, beneath 

 excavated and flattened, the distal angles each bearing a spine like those 

 above, but smaller and closer together.
