various parts of its body, more particular!}- tlie two ex- 

 tremities, a few scattered stifll' and short bristles: tlie anal 

 segment is without these two points directed backwards 

 which are of such common occurrence in some genera of 

 Geometers. The head and body are putty-coloured, but vary 

 very much in tint, some specimens being very light and almost 

 unicolorous, others (but generally the dorsal is decidedly 

 darker than the ventral area surface, and is transversed 

 throughout by interrupted stripes of a dingy smoky brown) 

 in some instances are entirely broken up into spots, in others 

 they exhibit a considerable amount of continuity ; the spiracles 

 are situated just within the dorsal area ; they are very small 

 and very black : there is a pale medio-ventral stripe rather 

 broad and intersected throughout by an indistinct but slightly 

 darker stripe ; it is bordered on each side by a very distinct 

 darker stripe ; these two darker stripes unite at the base of 

 the third pair of legs and also between the ventral claspers, 

 thus completely enclosing the medio-ventral paler stripe. In 

 confinement I found these larvae would only feed on broom 

 [Spartium scoparum) ; when full fed they spun rather com- 

 pact cocoons among their food, composed of the young leaves 

 and silk, and in these turned to shining pupa3 of a reddish 

 brown colour. The moth appears in June and July. 1 am 

 indebted to Mr. Doubleday for a supply of this larva, which 

 was unknown to me at the time of publishing the species in 

 my 'Illustrated History of British Moths.' — E. Neioman. 



Description of the Larva of Hade na. adnata. — The egg is 

 laid in June and July on the leaves of Salix caprea (sallow), 

 and the larva emerges in August; at first it is a dingy green 

 colour and without markings : it attains its full growth before 

 the end of September, and then rests in nearly a straight 

 position on the twigs of the sallow, but when annoyed it falls 

 to the ground rolled in a compact ring and feigns death ; in 

 this posture it remains but a ie^ seconds, and then reascends 

 the stems of the sallow with great activity. At this period it 

 nearly abandons the leaves of the sallow as food, and feeds 

 almost exclusively on those swollen flower-buds which con- 

 tain the male catkins of the ensuing year. Head semi- 

 ])orrect, subglobose, highly glabrous and scarcely narrower 

 than the Snd segment : body almost imperceptibly attenuated 

 at the anterior extremity, otherwise uniformly cylindrical, the
