part of each lobe; the mandibles brown. A broad, velvety 

 black band extends throughout the dorsal area, and is inter- 

 sected by the pale, greenish yellow indistinct dorsal line ; it 

 is also edged on each side with a clear yellow stripe, which is 

 again divided into black squares by clear yellow segmental 

 divisions ; these black squares vary in intensity in different 

 specimens, in some only occupying the anterior of the 

 segment, the other half being of the ground colour; all have 

 a mark of the ground colour, varying in size, on the posterior 

 part of the segments. The sides are minutely dotted with 

 gray, and there is a very indistinct yellowish hne along the 

 spiracular region. Ventral surface, legs and claspers green ; 

 of a darker shade than the ground of the dorsal surface. 

 AVhen young the black dorsal band, so conspicuous in the 

 adult larva, is absent. Feeds on alder ; and shortly before 

 spinning up the colour entirely changes, becoming dark 

 green with purple tinge, and the segmental divisions purple. 

 My larvEe spun loose cocoons amongst the leaves, &c. ; but 

 in a state of nature they probably form them amongst 

 moss, &c., on the trunks and about the roots of alder. — Geo.

Description of Varieties of the Larva of Notodonta Car- 

 melita.— Var. 1.— Ground colour white, with a greenish 

 tinge on the back, becoming more perceptible towards the 

 anterior segments. Down the centre of the back is a blue 

 line, extending to the last segment, distinct on the middle of 

 the segments, and becoming fainter, or sometimes entirely 

 disappearing in the inter-segraental divisions. On each side 

 of this line there are scattered a very few, exceedingly small 

 white tubercles, each bearing a hair. On each side of the 

 central line is another of a much lighter blue, and beneath 

 this the ground colour changes to bluish green, or sometimes 

 yellowish green. The spiracles are situated a little below this 

 line, and their colour is black, and each is surrounded by a 

 whitish line, and again a red line around this, the red being 

 more marked round the spiracles situated on the posterior 

 segments. Between the spiracles is a yellow line, which is 

 continued uninterrui)tedly over the non-spiracular segments. 

 Beneath the spiracles the tubercles are more numerous, and 

 in those segments bearing neither legs nor claspers a belt of 

 tubercles is continued under the belly. The legs and claspers
