Larva pale-yellow, very thin and fiat, elliptical ; length 

 about ^'jin. Dorsum bearing about twenty-eight rather long 

 slender spines, which may be considered as arranged in two 

 series, one submarginal, the other median ; the extremities 

 of these spines are dilated, and bear three very minute spicules. 

 Margin distinctly crenulated, but the tubes are very indistinct ; 

 there is no fringe ; there are three small marginal depressions, 

 one on each side opposite the rostrum, and one at the 

 abdominal extremity. 



Pupa-case pale-yellow ; elliptical, the cephalic region 

 somewhat acuminate; length about o^oin. The marginal 

 region is flat and thin, the portion covering the pupa con- 

 siderably convex ; the enclosed pupa is clearly visible. The 

 margin is as in the larva, with three depressions ; there is 

 no fringe. The dorsum bears, just within the margin, a 

 series of very long slender cylindrical spines, forty-eight in 

 all ; there is a second series of about sixteen (eight on each 

 side) following the base of the median convexity ; and a 

 third of six or eight on the median region ; the ends of 

 most of these spines are dilated as in the larva. Vasiform 

 orifice roundly subconical, with slightly concave anterior 

 edge ; operculum similar, nearly covering the orifice ; lingula 

 apparently obsolete. Eudimentary feet and antennae indis- 

 tinct. 



Adult form unknown.

This species seems to approach A. pJiiilyrca, Haliday 

 (Entom. Mag., 1835, p. 119), but differs in the absence of a 

 waxy fringe, and in the arrangement and the length of the 

 dorsal spmes. Signoret (Ann. de la Soc. Ent. de France, 

 Dec, 1867, p. 389) says of A. i)hillyrea that the " tubes of 

 the fringe are so conspicuous as to make it difficult to see 

 the spines, and it is only with a good light that these can be 

 made out." This is certainly not the case with A. hirsuta.
