AND THEIR TRANSFORMATIONS. 27 



SPECIES 1.— CONCEOA GUILDINGI.— (Plate 9.) 



This species is abundant during the spring- and summer montlis, in the ncigliboiirliood of Sydney, upon Ash Island, 

 and ni many other localities ; the larva feeding on Kunzea corifolia, Leptospermum lanigorum, Juncus effusus and a 

 variety of other plants. 



In form it is somewhat thick (flg. 1, ?), the body attenuating towards the extremity, the head and thoracic portion 

 corneous, of a dark cream colour spotted with brown, remaining segments dull black ; in length from i to f inch, according 

 to sex. 



The case is IJ inch in length, cone-shaped, thickly encrusted over with triturated portions of bark of a pale brown 

 colour, and carried when the caterpillar is in motion in an upright position, almost at right angles to the plane of the body. 



The Chrysalis (fig._ 2, ?) measures i inch ; wing cases reddish brown, abdomen yellowish brown ; that of the (? similar, 

 but mucli smaller and thinner. 



'the Aiiteimce, of the male (fig. 3) above sqviamose, below joints produced resembling serrations, each bearing 



ciliated tufts : of the female, filiform. 

 The Labial palpi, — (cJ divested of hair, fig. 5; ? fig. t) very small, projecting; 2nd and basal joints nearly of equal 

 length, terminal minute, pointed : the whole thinly clothed with hair. 



The Legs, rather weak, graduating in size, posterior pairs being the largest: 2nd pairs (fig. 6, ? ) with 2 spurs 



at apex of tibia, posterior pairs (fig. 7, (?) with •!■ longish spurs: tibiae and tarsi thinly clothed with 

 hair-like scales. 

 The wings dellexed in repose. 



The superior wings, head and thorax, of the female, are cinereous minutely barred transversely M'ith black ; the under 

 wings and abdomen, brownish gray : the whole sparingly covered with scales. 



The male resembles the female in all the markings, but the ground colour of the supm-ior Avings and thorax is of a 

 hoary white. 



The male and female in flight, and the conical habitation of the larva on Juncus effusus, are presented in the 

 illustration.

Female, winged. Fore wings somewhat trigonate, with their tips slightly rounded and costas arched. Abdomen 

 extending considerably beyond the hind wings, the ultimate segment fringed with longish hairs which partially conceal the 

 exserted ovipositor. Antonme long, filiform. Palpi porrected, and reaching a little beyond the front of tliehead; basal and 

 terminal joints equal in length, the latter slender and acuminated, middle joint more robust and longer tlian either. Legs 

 stout, the posterior pairs much the largest ; 2nd pairs with two, and posterior pairs with four longish spm's on tibiaj. Larva 

 thick, fleshy ; abdominal portions naked, thoracic corneous. Case cylindrical, pendent, composed of silk covered closely and 

 evenly with small twigs placed longitudinally. 



The CEcobia differs from the preceding genus, the Conocoa, by the trigonate wings, the much larger labial palpi, the 

 more powerful legs, and by the pendent and differently formed case.
