the body being more rolnist, and the wings and appendages more level 

 with, and less like, a cloak overlying it. The 8th abdominal segment 

 also has ? structure. The corona of the 10th segment and cremaster 

 appear to be identical in both sexes. A ? emerged November 

 21st, 1907. 



Explanations of Plates XI-XVII. 



Plate XI. — Fm. 1. — Empty eggshell (xlOO). The varying focus, due to the 

 curvature of the shell, gives the sculpturing as seen at different levels. The centre 

 is almost below the inner surface, round this the hexagonal markings are well 

 shown, outside this they are less distinct, but the black lines or points at the angles 

 appear, a little further out the focus fails. 



Fig. 2. — The micropyle ( x 250). The transverse lines in middle of figure are 

 merely the result of folding in pressing flat the stiff curved eggshell. 



Plate XII. — Fig. 1. — Eggshells (x30) are in sufficiently varied positions to 

 indicate the form of the egg, more easy to see than to describe, the sculpturing is 

 also indicated. 



Fig. 2. — Proleg of larva in penultimate stage, showing a continuous row of 

 crochets, of which the terminal ones are well-developed, the centre reduced to 

 chitinous nodules. 



Plate XIII. — Left half of prothoracic plate of fullgrown larva. The middle 

 line of plate is near right side of figure, its left margin in front of, and to right of, 

 the spiracle. The size and nature of the hairs are well-shown, and the colouring 

 and sculpturing of the plate are very fairly reproduced. 



Plate XIV. — Three skins of larva in 1st stage and one in 2nd, spread out fiat 

 ( X 15) to show the disposition of the tubercles. 



Plate XV. — Figs. 1 and 2. — Larva in .5rd instar "j 



Figs. 3, 4, and 5. — Larva in 4th (last) instar [ .., j,^ 



Fig. G.— Skin of larva in 4th (last) instar j "'•'*■ 



Figs. 7, 8, 9, and 10. — Four views of pupa j 



Platf XVI. — Fig. 1. — End of pupa. Showing crenulations of anterior 

 njargin of dorsal aspect of 10th abdominal segment. The reproduction in plate 

 indicates, but hardly shows, the fine spiculation along the margin of the crenu- 

 lations. The structure of the cremastral armature is well seen. The darker 

 portion of the figure is where, in the irregular breaking of the (brittle) pupa in 

 mounting, two thicknesses of pupa-shell are present. 



Fig. 2. — Male ancillary appendages (x30). Clasj^s spread to either side in 

 the manner that is most satisfactory in the majority of Noctuids and Geometrids. 

 To be compared with pi. xvii. 



Plate XVII. — Male ancillary appendages of (Fig. 1) Cleogene lutearia and 

 (Fig. 2) C. niveata (x30), mounted in the same way as those of C. peletieraria 

 (pi. xvi., fig. 2), for comparison. It is remarkable bow much more these are alike 

 than C. peletieraria is to either. 



The lifehistory of Chattendenia (Edwardsia) w=album. 



By A. M. COCHRANE. 

 The Rev. F. E. Lowe's "Notes on the lifehistory of Lcniqndea hoeti- 

 ciis" {antea, pp. 139 et seq.) must give all lepidopterists food for reflection. 

 How truly he says that chance makes some one particular family or 

 species of butterflies, a special favourite with most of us. He has told 

 us that, in his case, it is Laiiipides boeticiifi; that, so recently as 1899, he 

 wanted information of this species, which was that year breeding freely in 

 the Channel Isles from immigrant parents, that he searched in vain for 

 information through the available literature, and that, to date, no 

 consolidated reliable facts relating to the habits of this species have been 

 available, and now, suddenly, a detailed lifehistory of 50 closely-printed 

 pages (pp. 329-378) is placed at his (and our) disposal, much of it
