106 THE ENTOMOLOGIST. 



1908 : — There are now visible two young larvae very nearly full- 

 grown in their first instar. There may be others present, but 

 unfortunately various rosettes of the plant have died or are 

 dying, and it is feared the larvae on these have strayed away or 

 have died. The plants have been nearly cleared of aphides, but 

 it is not certain that these were the cause of their unhealthy 

 state. The larv£e still thrust their heads into the fleshy interior 

 of the leaves, mining out the tissue and leaving the upper and 

 lower cuticles as colourless pellicles. The larvEe are nearly 

 2 mm. in length, and are pale reddish, with the dorsal crest- 

 hairs black ; they are very evident when on a green leaf, but 

 match very closely the reddish dead leaves below the growing 

 rosette. Their ground colour is compounded of a pale, almost 

 yellowish, ground colour and dark reddish-brown markings. 

 The dorsal line is broadly red (brown), the lateral line pale. 

 Above the lateral line is a dark band, then a pale one slightly 

 echelonned, as bounding below, the next dark line, consisting of 

 the oblique lateral lines sloping downwards and backwards. 

 Between these and the dorsal band is a pale area, widest at the 

 posterior margin of each segment, and having a dark central 

 spot. Beneath the lateral line is a darker shade (paler than the 

 dark of upper surface), and then the pale ventral area. 



NOTE ON THE PUPATING LARVA OF ATTACUS 

 ED WARDS] I. 



By J. Henky Watson. 



In a batch of cocoons sent me from Calcutta, and despatched 

 thence on February 5th, was one cocoon that had a dull sound 

 on shaking it, as if the moth had become ready to emerge. I 

 opened the cocoon to see, and was very surprised to find that 

 the larva had never shed its skin, and had not advanced in its 

 pupation (after completing its cocoon) more than about five 

 days — that is to say, it had become dormant, and in this state 

 had travelled to England. At the time of writing it has been 

 at least a month in cocoon. The head, which is opaque and 

 yellow, is still retractable within the first thoracic segment, and 

 has the jaws, spinerette, and palpi quite and freely movable ; 

 but the antennae are withdrawn apparently from the larval 

 antenna cases. The true legs are movable about as much as 

 an ordinary larva is during moulting, and they have not been 

 as yet withdrawn from the larval shell. Whilst holding it on 

 the palm of my hand it made very free movements of the head 

 and thoracic segments, stretching them out, and making by the 

 rhythmic contraction of its body a vain attempt to walk ; the
