with yellow, the segmental divisions being of the 

 latter colour ; the head is uniformly pale green ; a 

 dark green pulsating vessel forms the medio-dorsal 

 line ; this is best seen in young specimens, as it ap- 

 pears to become less conspicuous as the larva ap- 

 proaches maturity ; there are no perceptible subdorsal 

 lines, and the spiracular lines are very narrow and 

 indistinct, faintly darker than the ground colour ; 

 spiracles imperceptible ; ventrally, the ground colour 

 is the same as on the dorsal surface, but has a con- 

 spicuous central stripe of pinkish-brown ; the legs, 

 prolegs, and anal points are also pinkish-brown. 



Feeds on sallow. 



The pupa is purplish and rather long. It is en- 

 closed in a very frail cocoon, amongst frass, etc., at 

 the bottom of the cage. 



The first larva spun on the 24th of July ; the moth 

 appeared on the 21st of August. (George T. Porritt, 

 February 3rd, 1872 ; Entom., March, 1872, VI, 49.) 



ClDARIA PICATA. 



Plate CXLII, fig. 8. 



The eggs were laid in confinement, singly, on the 

 leaves and stems of Alsine media (common chick- 

 weed) the last week in July, 1874. 



The young caterpillars were hatched on the 9th of 

 August, and moulted three times, about the 16th, 

 23rd, and 30th of the same month. 



When at rest they lie extended on the stem of the 

 food-plant, and when disturbed they assume the form 

 of an Ionic volute. 



The body of the larva is nearly uniformly cylin- 

 drical throughout its length, slightly increasing to- 

 wards the extremities. The head and face are of a 

 light yellowish-brown, marked with spots and short 

 lines of a deeper shade. The colour of the back 

 between the spiracles varies in different individuals
