of petty whin and ling in June. The egg is oval in shape, nearly 

 flat on both sides, and pale green in colour. The shell appears to 

 be smooth and shiny ; and the dimensions are •6mm. long, -imm. 

 greatest diameter, -Smm. thick. 



Thera jmiiperata. — I found an ovum of this species in February^ 

 near the base of a juniper leaf, on the upper surface, and partly 

 covered by the natural curling inwards of the sides of the leaf. It 

 is opalescent greenish in colour, oval in shape, and flattened above 

 and below. The sculpture is not bold, and takes the form of a 

 network of minute hexagons all over the shell. Length -GSmm., 

 width (maximum) -Smm., thickness -SSmm. 



Coremia unidentaria. — For this species laid wild I am indebted to 

 Dr. T. A. Chapman, who found an example in May near the 

 extreme tip of a blade of grass, on the upper surface, and fixed 

 slightly across the line of growth. It was oval, flattened above 

 and below, and tapered considerably towards one end. The colour 

 was pale yellowish-white, and the sculpture consisted of small 

 hexagonal depressions ail over the shell. Length -GSmm., maxi- 

 mum width -Smm., maximum thickness •4mm. 



Perizoma albidata. — Of this species I have but once seen the 

 ovum in nature. It was then laid singly on the calyx of a flower 

 of yellow rattle, and was very effectually hidden by the long plant 

 hairs with which it was surrounded. It is oval in shape, slightly 

 flattened above and below, of a yellow colour, and has a large 

 number of shallow pits spread over the surface of the shelL 

 Length -SSmm., width -drnm., thickness -Smm. 



Eiipithecia venosata. — I found these commonly when looking for 

 ova of caciibali, laid singly on the flower- buds of Silene infiata, both 

 in May and July. They are oval, much flattened above and below^ 

 yellowish- white at first, and purple-black just before hatching. 

 The shell, which has an appearance of semi-transparency, is 

 ornamented all over with minute pits. Length -Gmm., width 

 •45mm., thickness •2mm. 



Fmiomos fiiscantaria. — 1 have seen 24 of these curious brick- 

 shaped eggs laid in an irregular row along an ash twig. They 

 were placed side by side, touching each other, excepting where the 

 inequalities of the surface caused a slight separation. The shape- 

 is rectangular and flat, and the colour dark greenish-black with an 

 opalescent appearance. The surface of the shell is very slightly 

 reticulated, excepting at the micropylar end. Here there is a large 

 oval depression, surrounded by a whitish raised ring, of which the 

 edge is serrated. The opposite end is flatter, and has a less
