than the rest; they are strictly dorsal, and are seated imme- 

 diately behind the head, over which they are porrected. The 

 colour of the head is black, delicately reticulated with brown, 

 and having the crown of a still paler brown : body black, 

 with two yellowish, approximate, dorsal stripes, each about 

 equal in width to a medio-dorsal black stripe by which they 

 are separated; the sides are adorned with rust-coloured anas- 

 tomosing lines, extending from spine to spine, in three longi- 

 tudinal series ; all the spines, except two, are rust-coloured, 

 but originate in tlie black area of the sides; the two excepted 

 are those which ])roiect over the head : these are also rust- 

 coloured with black tips ; they originate in the yellowish 

 dorsal stripes already described : the legs and claspers are 

 smoke-coloured. Towards the end of May it attaches itself 

 by the anal claspers to a slight silken coating it has pre- 

 viously spun on the stem of a bramble or the twig of some 

 low shrub, and, suspended with head downwards, changes to 

 an obese, humped and angulated pupa, having a divided or 

 eared head, an elevated ridged thorax, and two rows of late- 

 ral abdominal tubercles, six in each row, and all having much 

 the appearance of aborted spines, and being very evidently 

 the representatives of the spines so conspicuous in the larva; 

 the two porrected spines on the 2nd segment are also accom- 

 panied by two tubercles just behind the head : the colour is 

 gray, delicately reticulated with darker shades, and often 

 adorned with spots and washes of the most brilliant and glit- 

 tering metallic lustre. The perfect insect appears at the very 

 end of June or early in July : I have always found the pupa 

 in June, In making my description of this larva 1 have 

 been greatly indebted to a most faithful coloured drawing 

 from the inimitable pencil of Mr. Buckler, who has also most 

 obligingly furnished me with the subjoined more precise 

 information respecting the identical individual he has figured: 

 — "A single whitish egg was discovered, from a careful scru- 

 tiny of a small bit of moss at the loot of an oak in a wood, by 

 the Rev. A. Fuller and a friend of his, who had previously 

 observed a worn female settled on it. The egg was given to 

 me early in August, and by the 1st of September, 1861, it 

 hatched a small black larva, which fed on Viola canina until 

 November, when I could no longer see it on thcjilant: it 

 had previously been about three lines in length : a fine web
