WHITES. 



in the year, the second of which passes the 

 winter in the chrysalis state. The head of 

 the CATERPILLAR is rather narrower than the 

 second segment of the body, and when at rest 

 is partially withdrawn therein ; the body is 

 uniformly cylindrical, the segments being per- 

 ceptibly but not strongly marked. Its entire 

 surface is covered with scattered warts, each 

 of which emits a hair : the colour of the head 

 is bluish gray, with a longitudinal yellow 

 mark on each cheek ; the body is of the same 

 bluish gray colour, with four yellow stripes, 

 two of which, rather broader than the others, 

 are dorsal and commencing at the head, where 

 thoy unite with the twoyollow marks already 

 noticed, terminate on the thirteenth segment ; 

 the other two stripes are lateral in the region 

 of the spiracles ; the warts are black. The 

 CHRYSALIS is attached by a belt, and also by 

 anal hooks ; the head is pointed ; the thorax 

 is keeled, and the sides keeled and angu- 

 lated ; the colour is pale brown, with several 

 spots of darker brown or black on the body.

TIME OP APPEARANCE. l\f ay and August. 

 The August specimens ouly are taken in this 

 country. 



LOCALITIES. Unrecorded as an inhabitant 

 of Ireland, Scotland, or the Isle of Man. In 

 England it seems to be almost entirely con- 

 fined to the coasts of Kent and Sussex oppo- 

 site the northern coast of France. A theory 

 broached by myself very many years ago, and 

 severely ridiculed by many of our entomo- 

 logists, under the name of the " blown-over 

 theory," suggested that we may be indebted 

 to winds, or the migratory propensity of in- 

 sects, for the few specimens taken in this 

 country of such species as Chcerocampa Nerii, 

 Lampides bcet'ca, and Pieris Daplidice. This 

 theory may, I think, fairly challenge investi- 

 gation, notwithstanding the unquestionable 

 fact to be presently adduced of the species 

 having been raised from the egg in this 

 country. I believe it is generally safer to 

 investigate a theory based on long experience 

 than to dismiss it as unworthy of consideration. 

 Paplidict has been reported from the under- 

 mentioned counties : 



Cambridgeshire. I took a fine specimen 

 near Whittlesea Mere on the 22nd or 23rd 

 of August, 1852, while at rest on the flower 

 of the wild carrot E. C. Buxton. 



Devonshire. At p. 398 of the second 

 volume of the " Zoologist," Mr. Lighten says, 

 " My cabinet has lately been enriched by a 

 specimen of Dnplidice captured in 1836 in 

 Roseberry Wood, near Exeter, by Mr. R. 

 Dawson." 



Essex. One was taken by Mr. Norman 

 Halls, nearDilbridge Hall, Colchester, on the 

 12th August, 1857 W. H. Harwood. 



Hampshire. Portsdown Hill H. H. 

 Crewe. 



Kent. At p. 113 of the first volume of 

 the " Zoologist," the Eev. W. T. Bree, once a 

 great authority in entomological matters, writes 

 thus : " Mr. Leplastrier, of Dover, cap- 

 tured last summer, near that place, two pairs 

 of the rare Pieris Daplidice. One of these, 

 fortunately, laid some eggs after it was cap- 

 tured, and from them Mr. Leplastrier reared 

 the caterpillars which he fed on the wild 

 mignonette (Reseda lutea), and at the present 

 time (Feb. 8, 1843) he has four of them in 

 the chrysalis state. The chrysalis, to my eyo 

 at least, a good deal resembles some of the 

 Vanessidce, were it not that, tinlike them, it is 

 fastened by a thread round the middle. Mr. 

 Leplastrier's specimens were taken, I think, 

 the end of July, or early in August, and if 

 so, it would seem there must be two broods 

 in the season." On the 18th of May of the 

 same year, Mr. Leplastrier writes thus to 

 Mr. Bree : "I have the pleasure of fulfilling 

 my promise, by informing you of the safe 

 arrival of my four specimens of Daplidice last 

 week, and certainly they are a splendid- 

 looking insect, and, of course, in fine con- 

 dition : there are three females and one male." 

 Mr. Bree adds : " The above notice may not, 

 perhaps, be wholly without interest to your 

 entomological readers, as it serves to point out 

 with precision the date when this rare insect 

 makes its first appearance on the wing."
