THE BRITISH NATURALIST. [NovEMBEft 



Length about five-eighths of an inch, and scarcely so stout as seems 

 usual in the genus. Head small, and narrower than the second 

 segment ; it is polished, rather flat in front, but rounded on the sides. 

 Body cylindrical, of fairly uniform width, but tapering a little at the 

 extremities, segmental divisions well defined ; the skin, with a soft 

 and half-transparent appearance, is sparingly clothed with short 

 hairs. There are two varieties, which are perhaps about equally 

 numerous. In one of them the ground colour is a bright grass-green ; 

 in the other, it is equally bright yellow-gre^^n ; in both forms the head 

 is pale yellowish-brown, very prettily reticulated with intense black. 

 The dark green, or in some of the yellow specimens dark brown, 

 alimentary canal forms the dorsal stripe ; sub-dorsal lines rather 

 indistinct, greyish white ; below there is a still more indistinct waved 

 line of the same colour ; there is, again, a similarly coloured faint line 

 along the spiracular region ; and the segmental divisions also are of 

 this pale colour. In some specimens the hairs are grey ; in others 

 brown. Ventral surface uniformly of the same colour as the ground 

 of the dorsal area ; the legs reticulated, and the pro-legs tipped with 

 black" ("Entomologist," Vol. XV., p. 44). A few months after (I.e. 

 p. 148), Mr. South again described the larva without, however, 

 mentioning its variation. 



Pupa — Of the pupa of this species, Mr. Porritt writes: — "The 

 pupa is attached by the tail only, is rather long, but slender. The 

 head, which is the thickest part, is abruptly rounded, and has the 

 snout very prominent; thorax and abdomen rounded above, rather 

 flattened beneath, and attenuated strongly to the anal point ; eye, 

 leg, and wing-cases fairly prominent, the last prolonged a considerable 

 distance over the abdominal segments. As in the larva, there are two 

 varieties; in one form, the ground is bright green, and there is little of 

 any other colour, the pale grey abdominal divisions, and two 

 indistinct pale lines on the dorsal area, with several faint purplish 

 spots behind the thorax and on the anal segment, being all that are 

 noticeable. The other form has the ground a dingier green, and 

 there is a distinct purple dorsal stripe, edged on each side with 

 greyish ; the abdominal divisions and the tip of the prolonged wing- 

 cases also purple. The pupa is capable of considerable movement, 

 arid, on being disturbed, turns up sharply the thorax and higher 

 abdominal segments, so as to bring them quite at right angles with 

 the several posterior segments. The first imago emerged on June 

 2gth, and was quickly followed by a good series, which varied in size 

 very much, some specimens being quite small. Two species of 

 parasites also emerged, one of them an Ichneumon witii a long 

 ovipositor, which Mr. Bridgman informs me seems new to science 



Entomologist," Vol. XV., pp. 44-45;. The pupa was also described 

 by Mr. South (I.e. p. 148).
