Tlie newly-hatched larva is about 1-45 mm. long, with pale brown 

 head, the body dead white, the usual bristles colourless and long. 



The full-grown larva is about 25 mm. long when walking, between 

 22 or 28 mm. when at rest ; stout in proportion, and cylindrical in 

 figure ; the head small and horny, the second segment, which is rather 

 long, tapering rapidly to it ; the thirteenth segment also tapers away 

 rapidly ; the segmental divisions well-marked ; the folds between the 

 thoracic segments complicated as in cuprealis ; each of the remaining 

 segments with an intermediate fold at about two-thirds of its length 

 from its front edge ; the head in colour chestnut-brown, very shining, 

 with the n:iouth blackish ; the second segment paler brown, rather 

 inclining to yellowish ; the anal plate also yellowish-brown ; the rest 

 of the skin most delicately shagreened, and in colour bone-white, the 

 belly whiter ; there is, however, a blackish tinge over the anterior and 

 posterior segments which, throughout the life of the larva, serves 

 (together with its stouter figure) to distinguish it from (EcopJwra 

 pseiidospreteUa and Endrosisfenestrella, which swarm where it is found; 

 the dorsal vessel is also distinguishable by its darker tint ; the usual 

 dots are small and indistinct, surrounded by small pits, and furnished 

 each with a short brown hair ; the trapezoidals arranged (as in AgJossa) 

 almost in squares ; near the front edge of each of the middle segments 

 is a transverse row, interrupted in the middle, of tiny shining fovese, 

 and behind it come short rows set longitudinally near the front pair 

 of trapezoidals, and again near the hinder pair, there are also others 

 below the spiracle ; the spiracles are small, round, and margined with 

 black ; the thoracic legs are of the ground-colour, but tipped with 

 chestnut-brown ; the ventral legs whitish, with the circlet of hooks 

 dark brown. 



The larvfe I had were living in long tubes of dusty flour spun 

 together rather toughly, and through which they could travel easily : 

 from one of them I bred an ichneumon, named for me by Mr. Bridg- 

 man, JExochus mansuetor. 



The pupa which I measured was about 10 mm. long, and not quite 

 3 mm. at its widest, in figure very cylindrical and plump, the wing- 

 cases reaching just half its length ; the tail ending in a blunt knob, 

 without a spike, but set with a group of six curled-topped spines, 

 arranged in three pairs of different lengths, the longest pair being 

 straight, and the other two curved ; the whole pupa-skin glossy, as if 

 varnished ; the wing-cases yellowish-brown, the abdomen redder, and 

 the segmental divisions still darker : the cocoon inside fitted the pupa 

 closely, and was made of tough white silk, well covered outside with 

 rubbish, and not very regular in outline, about ten lines in length, and 

 four in width.
