which forms itself into a kind of dorsal ornamentation, con- 

 sisting of a medio-dorsal and two lateral series of blotches ; 

 all these markings are very obscure, but there are two dorsal 

 dots, placed transversely on each segment, which are very 

 constant ; the ventral area is irrorated above the claspers, but 

 perfectly unicolorous and of a more decided green below 

 them ; legs and claspers concolorous with the ventral surface. 

 When full-fed the larva descends to the earth, and, changing 

 to a pupa just below the surface of the ground, spends the 

 winter in that state. The moth appears on the wing in June. 

 I am indebted to Mr. Doubleday for these larvse, which were 

 full-fed on the 31st of August. — Edward Newman. 



Life-liistory of Boiys terrealis. — The eggs are laid in 

 June, on the erect shoots of Solidago virgaurea (golden rod), 

 and the young larvse emerge in a iew days ; at first they eat 

 the leaves only, but no sooner do the flowers appear than 

 they mount upwards, and from that time eat flowers only, 

 stripping the entire spike. The full-grown larva rests on 

 the partial stalks of the scape of the golden rod, among the 

 flowers of which it spins a slight web ; when disturbed it 

 wriggles out of its retreat, falling to the ground, but never 

 rolls in a ring. Head flattened, glabrous, porrected on the 

 same plane as the back, narrower than the 2nd segment ; 

 body subfusiform, decidedly narrower at the extremities, and 

 having the incisions of the segments so deep as to give the 

 segments themselves a very tumid appearance ; dorsal area 

 of the 2nd segment very glabrous in front ; anal claspers 

 widely divaricating, extending considerably be3^ond the anal 

 flap ; all the segments have a iew small scattered lateral 

 warts, and every wart emits a strong lateral bristle. Head 

 semitransparent, its general area almost colourless, but orna- 

 mented with a few amorphous brown markiuL's : body dull 

 whitish, tinged with pink, and having a distinct and clearly 

 defined, pink, medio-dorsal stripe ; there is also an indis- 

 tinctly-serial arrangement of pink markings on the sides ; 

 warts black, bristles white ; ventral area, feet and claspers 

 dingy white. In some specimens the ground colour inclines 

 rather to dull orange than pink. At the end of August the 

 larvae descend, and spin a loose web under or below the 

 stones, and beneath this they live through the winter. Diu'ing 

 the following April they move about a little, and then spin a
