190 THE ENTOMOLOGIST. 



purplish velvety brown, with an interrupted and irregular 

 niedio-dorsal series of small and amorphous blue-gray spots, 

 and two lateral stripes on each side of the same colour, the 

 upper of these being the more perfect, and the lower con- 

 taining the black spiracles ; the space between these two 

 stripes contains a series of linear orange spots, one in each 

 segment ; the ventral area is black, freckled with white : all 

 the hairs are bright ferruginous. It feeds on Artemisia 

 niaritima (sea-wormwood), Statice Limonium (sea-lavender), 

 greatly preferring the flowering-stalks and flowers, and in 

 confinement it will eat the garden chrysanthemums : it is 

 full-fed about Midsummer-day, when it spins a rather large 

 and rather tough oblong cocoon of fine pale-coloured silk, 

 interspersed with a powder much resembling flower-of- 

 sulphur, the nature and uses of which are unknown ; it 

 appears to give no strength or support to the fabric : in this 

 cocoon it changes to a black dull-looking pupa, the cuticle 

 of which is transversely striated, and thinly clothed with 

 short ierruginous hairs ; these are most abundant at the anal 

 extremity, which is prolonged and produced, but blunt. I am 

 indebted to Mr. Button for a most liberal supply of these 

 larvae. The moths appeared throughout July.' — E. Newman. 

 Description of I he Larva of Ac id alia, emutaria. — The full- 

 grown caterpillar rests in a nearly straight position, with its 

 claspers firmly attached and its head porrected on a plane 

 with its body ; the legs are also porrected, closely appressed, 

 and crowded together : when annoyed it tucks in its head 

 very tightly, and, if the annoyance be continued, it eventually 

 lalls to the ground in a tolerably compact ring, but with the 

 head on one side, feigning death : ihe head is about equal in 

 width with the 2nd segment, and the body thence gradually 

 increases in width to the anal extremity : it is slightly 

 couipressed, the sides being slightly dilated ; it is regularly and 

 very delicately wrinkled transversely, and every part of the 

 body emits scattered bristles ; the head and body are pully- 

 coloured, the head having four lougitudinal stripes of a very 

 jiale brown, but still a shade darker than the ground colour : 

 the body has a double medio-dorsal stripe, rather incon- 

 spicuous and of a sienna-brown colour, throughout the greater 

 part ol its course, but more conspicuous at the incisions of 

 the segments, wiicre it forms two small brick-shaped spots ;
