250 THE entomologist's record. 



above the widest part ; the egg looks solid and strong when 

 compared with the glassy delicacy of nearly all Acronyctas, 

 orion especially. 



The newly hatched larva (PI. IX.) is cylindrical, the 

 1 2th segment perhaps a little pronounced, otherwise no sign 

 of any segment being "weaker" either in form and colour 

 than any other ; the head is black, and there is a black plate 

 on segment 2. The colour is rufous, with paler lines and black 

 points and hairs, producing a general fuscous effect. The 

 anterior trapezoidal possesses three or four hairs, the posterior 

 one, the lateral many. The hairs are long, about twice the 

 diameter of the larva dorsally, those of the large lateral 

 tubercles three or four times, and those on 13 and 14 are as 

 long as the larva, viz., 2 mm. As the larva feeds up, various 

 reddish marblings appear along the subdorsal region. The 

 hairs are ringed darker and paler, like porcupine quills. The 

 abundance of hairs and their length, the character of the 

 tubercles, the anterior trapezoidal being more important than 

 the posterior, the colouring, all point to Liparis rather than 

 Acronycta as the nearest affinity. 



In the second skin, the larva is rufous with a whitish dorsal 

 line, a faint one between the trapezoidals, and one more dis- 

 tinct below posterior trapezoidal. The inner trapezoidal on 

 3 and 4 is either lost or fused with the outer, which is broad. 

 The other trapezoidals are of about equal size, and the super- 

 and sub-spiracular rather larger. The lateral tubercles of the 

 2nd segment are very large, as are those of 12 and 13. A 

 peculiar central dot occurs on segments 3 and 4, and on 5 to 

 II or 12 is a depression, with a corneous point immediately 

 behind the anterior trapezoidal in the position of a peculiar 

 organ in various Liparids {e.g., monachd). 



In the next (third) skin the length is 10 mm. The larva now 

 shows variation in colour, as when full grown ; some being 

 white, some black, some rufous, etc., with intermediate and 

 piebald forms. The 5th and 6th and 12th and 13th segments 

 are more pronounced than the others, are darker and have 

 larger tubercles. The dot on 3 and 4 still exists. 



In the further skins it acquires a more Liparid general ap- 

 pearance from the anterior and posterior bunches, rather 

 perhaps than brushes, of hair, but it does not acquire any 

 dorsal brushes or glands, nor do the organs noted in the second 

 skin acquire further development ; but even so far they are 

 very characteristic.
