exception that the abdominal segments 5, 6, 7 and 8 are ridged at the 

 lower edge, and the cremaster is reduced to a blunt point, with very 

 stout pyramid-shaped projections on it. In fact, the cremasters of this 

 species,*' S. pijri, and A'ndroinis versicolor, form a very good series of 

 connecting links between the anal spike of the Sphinx pupa and the 

 bristly cremaster of S. paconia. The order will be as follows : S. 

 jiaronia, S. pyri, E. versicolor, the South African Saturniid and the 

 Hawk moths, e.(i., Smerintkm or Acherontia. 



* I have been unable to name this species yet. It does not appear to be in the 

 National Collection.

Description of eggs of Lepidoptera. — Dianthoecia hiteaf/o var. 

 bar ret t a. — The ovum is of a honey-yellow colour when freshly laid, 

 globular, but somewhat flattened equatorially in shape, and the 

 micropylar area slightly depressed, which disappeared as the embryo 

 developed. Under a low power, they exhibited minute pittings, 

 diverging in rows from the apex. The larvae were discernible within 

 the transparent pellicle in eleven days, fully developed, and emerged 

 next day. 



Stilbia anomala. — The ovum globular, viewed from above ; from 

 the side, the base is flattened, and the apex bluntly conical. Orange 

 in colour, and strongly ribbed, the ribs radiating from the apex.—

Neuronia popularix. — A 5 taken at light on evening of Hept. 6th, 

 1896, deposited a few ova, singly, in collecting box. When fresh 

 they were of a pearly straw colour, subsequently (? on formation of 

 larva) turning leaden, which colour they were to the naked eye, with 

 a darker spot in centre, when described. Under a lens the shells 

 were seen to be transparent, and the larvae could plainly be seen inside, 

 fully formed, ready for hatching, being of a metallic green colour, and 

 thus giving the eggs an iridescent appearance. In shape, like an 

 apple or an orange, from which about ^ of the height has been cut off 

 at the bottom, forming a slightly concave base, and which (the 

 orange) has been pressed down from above to form the micropylar 

 depression, thus causing the circumference to bulge (? = depressed 

 sphere). The height about equals, and, in some instances, slightly 

 exceeds, the diameter of the base. Thickly ribbed longitudinally from 

 the centre of the micropylar depression to and into the concave base, 

 the ribs and interspaces being of about equal width. [The description 

 was made on March 9th, 1897] .— E. F. C. Studd, M.A., F.E.S. 



L'atocala nupta. — Eggs laid on the flat surface of the box, slightly 

 imbricate. The base is flattened, and the egg forms a very depressed 

 cone in shape, the apex (the micropylar area) being flattened. The 

 colour of the Qgg is pale creamy-grey, with dark purplish markings 

 (due to embryo within). There are about 36 slender prominent 

 vertical ribs, very shining and silvery on the ridges, uniting in twos 

 or threes (although some remain single) on the shoulder of the egg, 

 so that about 15 or 16 run on to the micropylar area. The micropyle 

 is conspicuous, stellate, somewhat rosette-like in appearance, formed 

 of irregular, quadrilateral cells outside, and smaller, more rounded 

 cells towards the centre. These are arranged concentrically. There
