Description of the Larva of Nociua rhoinhoidea. — The 

 egg is laid on Stellaria media (chickweed) and other low 

 plants, at the roots of wliich it hybernates when small : in 

 the spring it feeds on chickweed, dock, &c., but also ascends 

 the sallows and feeds on the young leaves ; very generally 

 full-fed about the end of May or beginning of June. Head 

 almost prone, rather small, generally half-concealed in the 

 2nd segment: body smooth, velvety, almost uniformly cylin- 

 drical, but having the 2nd, 3rd and 4th segments more slen- 

 der than those which follow. Head brown, shining : body 

 with the dorsal area as far as the spiracles brown, but the 

 tint of the brown different in different individuals, approach- 

 ing sometimes to sepia, sometimes to sienna ; this brown 

 area is divided by three equidistant narrow stripes of a pale 

 greenish hue, and these three linear stripes are connected 

 on the 12th segment by a transverse bar of the same colour ; 

 the back has several black markings, almost taking the cha- 

 racter of dots ; the belly below the spiracles is pale olive- 

 green. The moth appears in July and August. 1 have been 

 greatly assisted by Mr. Buckler's beautiful drawing, by which 

 1 have recognized larvae of this species lent rae by Mr. 

 Thomas Huckett. — Edtvarcl Newman. 



Description of the Larva of Nociua xanthograpJia. — The 

 eggs are laid in August and September, on the leaves of 

 Plantago major (plantain) and various species of grass, which 

 constitute the food of the larva ; it retires towards the roots 

 when very small, secreting itself luider any covering that will 

 protect it from the weather ; at this season, and again in the 

 spring after it has again commenced to feed, it is very fond 

 of hiding on the under sin'face of stones, if such occur near 

 its habitat. The full-fed larva drops from its food-plant 

 when annoyed, and rolls itself into a very tight and coujpact 

 ring, but quickly unrolls when the danger is passed, and 

 crawls with considerable activity. Head in crawling scarcely 

 porrected, manifestly narrower than the body : body obese, 

 almost uniformly cylindrical, but still increasing very gra- 

 dually from the 2nd to the 12th segment. Colour of the 

 head pale semitransparent brown, very glabrous, with two 

 slightly curved longitudinal dark stripes on the face, and the 

 cheeks slightly reticulated with the same colour : body pale 

 velvety brown, with a narrow uiedio-dorsal stripe still paler,
