THE ENTOMOLOGIST. 859 
sides are dilated by the presence of a manifest skinfold, 
which extends its entire length; the back is transversely 
wrinkled or divided into numerous sections ; the number must, 
however, be taken as subject to future investigation, as 1 have 
only counted the sections in four segments and in two 
specimens; the legs are crowded together, and when the 
larva is annoyed it bends the head downwards until the 
mouth and legs come in contact, the flattened character of 
the face entirely disappears, the anterior extremity appears 
truncate, and the legs are concealed by their close approxi- 
mation to the body; the ventral claspers are only two, and 
there is no trace of the other pairs; the anal claspers are 
rather slender and spreading; the ventral surface is wrinkled 
like the dorsal, but the sections are narrower, thus allowing 
free play to the movements of the body in crawling ; scattered 
bristle-like hairs occur on the head and on various parts of 
the body: the colour is pale putty-colour, the lateral skinfold 
rather lighter, and the ventral surface rather darker, inclining 
in one specimen to smoky; in each dorsal interspace, begin- 
ning with the sixth and ending with the tenth, are two closely 
approximate and nearly square black spots; in advance of 
these and rather nearer the head there is another black spot 
on each side of each segment; and again on each segment, 
still in advance of these markings, is a transverse series of 
four other linear indistinct black markings. These larve 
were full fed on the 18th of June, when they left the food, 
and descending just below the surface of some light earth 
provided for them, they spun a very slight web, composed of 
a few silken threads attached to particles of earth, and 
in this changed to pupz on the 25th; the colour of the 
pupe was bright light-brown, and the surface exceedingly 
glabrous ; the head rounded; the wing-cases ample, extend- 
ing two-thirds of the entire length; the anal segment 
produced into a nipple, and furnished at its extremity with 
two spines directed backwards; these are parallel at first, 
but each is bent outwards at its extremity. I am indebted to 
the kindness of Mr. Barrett for a supply of these interesting 
larve, and for particulars of their early life-history. With 
me they fed exclusively on Clematis vitalba (traveller’s joy). 
This is the Geometra strigillata of the ‘ Vienna Catalogue,’ 
but not of Hiibner, whose insect still retains that name. It
