lines, but there are long and continuous whitish streaks along the posterior 

 half of the spiracular region. Head bright, yellowish-brown, the 

 mandibles reddish-brown, and the ocelli black and distinct. Tubercles 

 intensely black, the hairs greyish. The imago from this larva was out 

 on the 31st May " ("Entomologist's Monthly Magazine," Vol. XIX., 

 p. 187). Mr. South gives the following description of the larva : — "Length, 

 8 lines ; fairly stout, tapering slightly posteriorly. Head smaller than 

 second segment, shining, yellowish ; face pale greenish, a dark- brown spot 

 on each cheek ; mandibles pale brown. Ground colour green ; the 

 dorsal area is margined by narrow whitish lines running from the 3rd 

 segment ; on these lines at the posterior edge of each segment is a large, 

 somewhat triangular yellow spot, the enclosed ground colour is thus 

 formed into a series oi lozenges, intersected by the darker intestinal 

 •canal; the yellow spots on the 9th segment coalesce, forming a con- 

 spicuous blotch. Tubercles, two dorsal rows (two on each segment), 

 black from 5th to nth segments inclusive, the others are oi the 

 ground colour ; each emits a tuft of hair of unequal lengths, the shorter 

 ones are whitish and the longer dark grey ; two long grey hairs project 

 over the head from the edge of the 2nd segment, and there are also 

 single grey hairs of considerable length rising from each of the dorsal 

 warts on the 2nd, 3rd, 4th, nth and 12th segments; those on the 

 anterior segments stand nearly erect, whilst those on the posterior 

 segments curve backwards. Subdorsal, a row of black warts with tufts 

 of short whitish and longer dark grey hairs ; the spiracular row of warts 

 are transparent and emit hairs, as in the subdorsal set. Prolegs and anal 

 claspers semi-transparent, tipped with pale brown. May and June, on 

 convolvulus {Calystegia sepium), eating the leaves and flowers; rests on 

 the underside of the leaves and on the stems" (" Entomologist," Vol. 

 XVI., pp. 26—27). 



Pupa — The pupa is attached by the anal segment to the food plant. It 

 is of a green or greyish-green coloration, and varies somewhat consider- 

 ably in the quantity of black dorsal markings which are arranged in three 

 rows longitudinally. The pupa is described by Mr. South as follows : — 

 Pale green at first, afterwards greyish-green, with> three rows of black 

 dorsal spots ; hairs similar to the larval arrangement ; fastened by the 

 tail to a leaf or stem. May and June " (" Entomologist," Vol. XVI., 

 p. 27). 



Habitat — The species is certainly widely distributed, but does not 

 occur " everywhere," as some of our authors remark. Mr. Baxter of 

 St. Anne's-on-Sea informs me that it does not occur in that part ot 

 Lancashire. It is recorded by Mr. W. F. de Kane from "Wicklow and 

 Galway " ; by Mr. A. W. P. Cambridge from " Wareham (common) " ; 

 by Mr. Sinclair from " Sutton, co. Dublin " ; from " Leominster," by Mrs. 

 Hutchinson as "Common in May and June on convolvulus;" but it
