AND THEIR TRANSFORMATIONS. 29 



extremity is similarly concealed by long thick hair, and consequently unless the caterpillar is in movement, the proper identification 

 of head or tail is nearly impossible. The head is dark lilackish-brown ; thoracic feet dark reddish-brown ; abdominal and anal 

 claspers reddish-brown with straw coloured markings. The male larva is similar, but rather darker in colour, and measures about 

 three inches. 



Two of the caterpillars found in March, prepared for the chrysalis state early in April, exhibiting great restlessness and a 

 desire to escape from confinement ; moving about incessantly for two days until they became almost exhausted. One finally spun 

 its cocoon beneath a piece of dried bark, attaching to it sundry small twigs — the other selected the corner of the feeding cage. A 

 loose web of yellowish silk was first spun in various directions, as an outer support, and then inside this several other layers of 

 silk were woven, having the hairs of the caterpillar sticking through ; each of these layers was of distinct formation, and could be 

 peeled off sei)arately. Within these outer envelopes was the cocoon itself, rather oval in form, lightish brown in colour, and 

 strongly coriaceous in texture ; the interior beautifully smooth and satiny, and with a small slit at the upper end, apparently for 

 the more easy exit of the moth. 



The chrysalis (fig. 1, female) measures 1} inches in length, and a little under half an inch in width; the male is about 

 1 inch, and more slender. It is throughout light bistre-brown, darker near the abdominal divisions, the wing-cases, head, etc. 



The moths took wing in the middle of the February of the following year. The female measures slightly over 3J inches ; 

 the male 2J inches. 



The Antenna (fig. 2) male, moderately bipectinate throughout ; pectinations finely ciliate, and each terminating in a 



seta. Of the female, rather short, thin, and with very small bipeotiuations (fig. 3). 



The Labial palpi in male (fig. 4) project upwards, nearly even with the top of the eyes ; in female very small, bending 

 slightly downwards. In male the basal and second joints are twice the length of the terminal, which is 

 rather obtuse at apex ; in female the basal joint is slightly longer than the second, and rather acute at 

 apex (fig. 5, denuded of hair). The whole moderately hairy in the male, but less so in the female. 



The Maxilla obsolete. 



The Legs : anterior pair spurless (fig. C, female) ; intermediate and posterior pairs (fig. 7, male) with two short spurs 



at apices of tibiae. The whole moderately hairy, but with the hairs thickest on the tibi* of anterior pair ; 

 a few rows of small seta? on the tarsi, and some long hairs beneath the femora of the male. 



The wings are semi-deltoid in repose, the anterior angle of the lower wing projecting slightly beyond the costal margin 

 of the upper wing. Moth nocturnal. 



The upper wing of the female moth is elongated, the costal margin arched, with the apical angle produced and rather 

 falcate, and the exterior margin much rounded. The lower wing is slightly produced at both the apical and anal angles, and has 

 the exterior margin rounded. The general colour of the ui)pcr surface is drab, tinged with pale ])rown along the exterior margins, 

 and with dark brown at the base of both wings. Two wavy bands or fascice of ochreous-yellow bordered with dark brown pass 

 transversely across both wings, commencing near the middle of the interior margins, and terminating with a slight curve, on the 

 costal margin in front of the discoidal cell. The outer of these bands is scalloped near the interior margin of the upper wing, and 

 relieved behind with rich brown, but the scallops become very indistinct towards the apical angle. On the lower wing the scallops 

 are very regular and are continued across the wing, the rich Ihowu backyrouud bringing them into strong relief. A wavy brown 

 border incloses the dull olive-brown basal portion of the wings, and inside this, on the upper wing, is a second wavy dark band. 

 There are also two brownish patches near the apical angle of upper wing, and a distinct dark discoidal spot. The antennae are 

 yellowish above; the head very small, and like the thorax and abdomen, drab-coloured; the latter being stout and projecting a little 

 beyond the lower wings. Margins of all the wings fringed with short yellowish cilia. On the under side the female is uniformly 

 silvery-drab, and the transverse fascite are very faint in colour. The legs all bear a conspicuous silvery-white spot near the 

 junction of femora and tibiae. 



In the male the upper wing is rather triangular, and not arched on the costa, or rounded at the exterior angle, as in the 

 female. The general colour and markings are very similar to those described in the female, but are lighter. There are also two 

 dark discoidal spots, one placed behind the other. The thorax and abdomen are very pilose ; the latter is rather short, not 

 extending beyond the lower wings, and tufted with brown hairs at the extremity. The under side is silvery-drab, with two faint 

 fascia, and two distinct brown discoidal spots on each wing. Th(> anteniue, front of head, thorax and abdomen, are yellowish ; 

 legs brownish, with silvery-white spot on each femur. In both sexes the basal half of the wings is very pilose on both the upper 

 and under sm-faces.
