AND THEIR TRANSFOEMATIONS. 16 



The^cocoon is fon.KHl of a-lutiimtcul parti.-los of earth, and is placed near the surface of the ground. The chrysalis 

 (hg. 1) IS :, inch ni length, and throughout dark l.rown, of soineNshat attenuated form, the extremity truncated. The perfect 

 msect measures slightly over 2 inches. 



'^^^^ ^'"'''"""' (lig-- --^l tliiu and long, gradually and slightly thickening towards the middle, then tapering to a point. 



The Lahial palpi (lios. ;} a,,,! 1) three-jointed ; basal and middle jomts nearly equal, covered with scales, and himches of 

 long haus underneath ; terminal joint ahout half the length of preceding and nearly smooth ; the whole 

 projecting forwards. 



The La/.s.- anterior pair spurless; second with two spurs; posterior pair (fig. 5) with four spurs, two at apex and two 



on muldle tihifij. Tibitc and tarsi clothed with hair-like scales, the former with long tufts of hairs on 

 the anterior portions. Tarsi live-jointed, with rows of small settc internally, and terminated by small 

 claws. 



The colour of the entire upper surface is velvety jet black with several transverse bands or patches of pale straw colour on 

 the upper wings, the outer one being much the largest; close to, and parallel with, the outer margin, is a double row of short 

 longitudinal straw-coloured lines. In most instances the lower wings have no markings, but in some specimens, as in the one 

 depicted, there is a distinct transverse spot or patch in the centre. Marginal fringe of upper wings ])lack, with white at tips and 

 anal angles ; of lower wings alternately black and white. Thorax and abdomen black ; the former with longitudinal bands of 

 straw colour, the latter with a lateral row of sujiill yellowish spots, and tufted posteriorly with vermilion-coloured hairs. 



The larva, with its food plant Epilohiuin juncctDii, and the perfect insect, are figured in the plate. 



[Professor McCoy states that the Aijarista Lewini is not uncommon near ^Melbourne, the larva feeding on the Epilohium 

 tetrafjonum, which is an abundant weed. The figures given in his illustration, I)oth of the larva and imago, are very much inferior 

 in size to those bred by us in Jsew South Wales | .

It is evident, from the observation cursorily made by Lewin in 1805, that the caterpillars of this Agarista "feed 

 sometimes on the grape vine," that they had not then developed the destructive characters which they have since assumed, and 

 which fairly entitle them to a foremost place in the list of pests dangerous to the viticulturist. They enjoy immunity from birds, 

 either owin" to the acrid greenish juice which they eject from their mouths when alarmed, or from some other protective 

 influence and thus small armies carry on their work of destruction in the vineyard until scarcely a whol(« leaf is left. Nor arc 

 their ravages confined to the grape vine, as many of the introduced species of Vitis and Cissus, the Virginia Creeper, i-c, are 

 completely destroyed by them. 



When fall grown the female larva measures 2 inches ; the ground colour is very pale creamy-white, relieved by numerous 

 irregular annular black lines and spots, forming an intricate but symmetrical pattern divided down the centre of the back, and 

 bordered on each side by a narrow but distinct whitish horizontal band. On the penultimate segment are four conspicuous and 

 sliRhtlv protuberant deep crimson spots of graduated size ; the stigmata, with the exception of those near the head, are also deep 

 crimson • and beneath these, over the legs, are shining ochieous si)ots, connected with each other by a hue ot irregular spots 

 of pale c-miboge yellow Head and upper part of first segment shining ochre, with several black divisions or markings ; feet and 

 legs larg'c shinin.^ ochre, with black tips ; whorls of fine whitish hair on each segment. In some specimens there is an additional 

 row of small crim'son spots over the stigmata, but tins may be a sexual distmction.
