LIFE-HrSTORY OF LOPHOPTERYX (oDONTOSIa) CUCULLA. 251 



tubercles on the upper edge of the subdorsal line and in it, and arranged 

 as a triangle with apex behind. Tubercle iv is represented by two 

 large black tubercles close together and above the spiracle, and tubercle 

 V is in front of and below it. Tubercle vi is represented by two black 

 tubercles close together in the subspiracular brown line. On the meso- 

 and metathorax where there are no spiracles, tubercles iv and v are repre- 

 sented by three tubercles and setfe arranged in a semicircle, concavity 

 facing backwards, and tubercle vi is in a whitish area in the subspira- 

 cular line. On abdominal segment 1, tubercles i and ii are in the 

 normal position and conspicuous, tubercle iii in the supraspiracular 

 region, tubercle iv is very small and inconspicuous and postspiracular. 

 Tubercle v is subspiracular, and tubercle vi is made up of three tuber- 

 cles, two above in whitish area in the subspiracular line, and one less 

 conspicuous below. Tubercles i on the other abdominal segments are 

 not so conspicuous as before. On segment 2, tubercle ii is represented 

 by an inconspicuous black dot and seta; tubercle iii is large and black. 

 On segments 3 to 10 tubercle iii is black, but smaller, and placed in 

 paler area. The other tubercles are similar, but inconspicuous, except 

 on segment 7, where tubercles iv and v are black and on the same level 

 below the spiracle, and there is a delicate seta behind in the usual 

 position of tubercle iv. On segment 8, tubercle iv is indistinctly repre- 

 sented immediately behind the large spiracle, and has two black sets, and 

 tubercle v is very conspicuous and below it, as usual; the tubercles form- 

 ing vi are placed in a greyish-green shade below the spiracles, and are 

 three in number with black setiB in whitish area, and on segments 1 and 

 2 are arranged in the form of a triangle, apex downwards. On segments 

 8, 4, 5, 6 the sette forming tubercle vi are linear, one in front and two 

 nearer together behind; on segments 7, 8, 9 there are only two, and 

 on segment 10 one ; the tubercles forming vii are colourless, with 

 colourless setae. The hump on segment 8 is very prominent, bifid and 

 red-tipped, with eight black setae. The larva is now narrowest in 

 front, tapering from the middle. At rest it raises its anterior extremity 

 upwards from the 1st abdominal segment, as well as its hinder from 

 the 7th. 



After si.ith monlt. — July 20th. — Length, 80mm.; larva, stouter, and 

 eating greedily, as shown by the frass; colour, pearly-white on dorsum, 

 pearly-grey mixed with primrose on the sides; subdorsal lines, prim- 

 rose ; there is a mottling of both colours in the supraspiracular region, 

 shading off above and below ; undersurface, whitish-green ; dorsal 

 patch, greener than hitherto ; tubercles and setae, as after fifth moult, 

 only less conspicuous ; clypeus, much flattened ; prolegs, pinkish ; 

 appears to be nearly fullfed. One larva has much more green in its 

 colouring than the other. On July 21st the two larvae were still feed- 

 ing greedily. All the markings similar, but paler and less defined. 

 Length when extended 80mm., when at rest, in characteristic position, 

 measures about 25mm. On July 22nd one larva became glaucous- 

 green, losing its yellow colour, and the other, a more whitish-green, 

 retaining some yellow ; both becoming shorter and stouter with less 

 distinct markings. They remained in this state for two or three days, 

 and then changed into pupfe on the surface. 



Description of two inip(C. — Smooth, shining, blackish-brown ; one, 

 18mm. long and 6mm. at its broadest part (5th segment) ; the other, 

 17mm. and 5mm. The pupa tapers gradually to the anal extremity,
