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 larvae 

 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 pupae on the 25th ; the colour of the 

 pupae 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 

 larvae, 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 Hlibner, whose insect still retains that name. It
