PVRAUSTJD.-E—BOTVS. 205 



little, ia part, to bluish-green ; spiracular stripe yellowish- 

 white, extending to the anal prolegs, having throughout its 

 course, on every segment, a concave upper and a straight 

 lower edge, thickening the stripe at each segmental division, 

 and thinning it in the middle, just where each round black 

 spiracle is placed upon it ; undersurface very pale watery- 

 green with an even paler line under the spiracles ; raised 

 spots of the colour of the surface on which they occur, but with 

 a central black dot bearing a fine hair ; the whole skin very 

 glossy and shining. (Condensed from Mr. Buckler's 

 description.) 



August and September, on Teucrium scorodonia (wood- 

 sage), hiding in the daytime under a leaf where it has con- 

 structed a faint covering of white silk, when older sometimes 

 uniting two leaves slightly together; eating holes in the 

 leaves from the underside. 



Pupa three-eighths of an inch long, moderately slender ; 

 thorax slightly keeled ; spiracles on the fixed segments of the 

 abdomen rather prominent and larger than those on the 

 flexible rings ; wing-covers long ; leg and antenna-covers 

 longer still ; abdomen tapering, the anal segment rather 

 blunt, cremaster prolonged and more pointed, furnished with 

 two minute converging bristles ; colour shining ochreous- 

 brown. In an oval cocoon about half an inch long, of tough 

 grey silk covered with sand, in the ground. In this cocoon 

 the larva lies through the winter, assuming the pupa state in 

 the spring. 



The moth hides during the day among its food-plant, the 

 wood-sage, usually preferring open patches of the plant on 

 heaths, or rough ground, or loose sandy woods of larch or 

 fir; but is seldom to be found where the plant grows upon 

 hedge-banks, or in dense woods. It keejos quite closely to 

 these patches, and is not very willing to move in the day, 

 though a few specimens may usually be trodden up. These, 

 however, bear but a small proportion to the number that
