in the neighbourhood of Salix arctica and Saxifraga oppositifolia ; it does 
not appear to belong to the moth just described, being, apparently, 
too large. It is of that tribe of caterpillars which Reaumur calls Chenilles 
a brasses, the perfect insects of which constitute the genus Laria of Schranck, 
for instance, Bombyx fascelma Fab., &c.. It has six true legs, and ten 
spurious or membranaceous ones, (Propedes Kirby and Spence.) The body 
is thickly covered with very long hairs of a dirty tawny colour ; in the middle 
of the back are three small pale orange brushes, just before which is along 
black one, or rather three confluent black ones, and another of the same colour 
at the tail, all forming pencils of longer converging hairs. It appears not to 
have arrived at its full size.

the base and apex of the thorax, and the anterior half of the upper side of the

ones. The legs, also, particularly the anterior pair, are clothed with long 
yellowish hairs. The antennae, which have a joint more than those of the
