Several references have been made in recent issues of the A(jrtralturt only the largest veins. This insect is one of the ' loopers' or 'measuring worms.' These names are given because the larva travels by arching its body and bringing uj) its hind legs to the forward ones and then reaching out again to get a new hold with the for- ward pairs. This pecuHarity is shown even in the earliest stages. The development of the cater[>illar requires from one to three , and during this period the skin is shed five times. When first hatched, the larva is yellowish in colour but .soon Larva of Ahfhi inijiJInriH, becomes greenish with numerous enlarged ; actual length indi- black spots and yellowish longi-''•?'t^l by hair line, tiidinal lines. The fully-grown «, side ; b, dorsal Cotton \\ orm. larva measures nearly li inches and is (juite .slender. The head is dull olive-green ; a very fine bluish-white line extends along the middle of the back the entire length of the body. On either side of this fine line is a wider green line : each of these being, in turn, bordered by a yellow band. There are two rows of black spots along the back —one rr)W in each of the yellow bands—each of the black .spots has a fine stiff hair oi bristle arising from its centre, and careful examination will show a fine white ring outside the black of each spot. The sides are olive-green with several more or less interrui)ted lighter lines running lengthwise, the lower one being continuous. There are black sj>ots on the sides also, which are like these on the back except tliat they are smaller, and are not arranged in regular rows. There is much variatif>n in the colour of the larvae at different seasons of the year, the earlier broods being lighter and the ' later ones darker.
