368 ITEROPHORUS LIENIG1ANUS. 



Every one must have observed that when a plume 

 moth emerges, the pupa bends back so as to allow the 

 moth to use its long ]egs as soon as they are freed 

 from the envelope. 



The deserted tent is a curious object, with its 

 oblong windows edged with white down, and its seams 

 made as neatly as a spider even could do it. In the 

 case of large leaves, only one of the divisions is made 

 use of, the whole leaf being beyond the powers of the 

 architect. In confinement, these larvse, like those of 

 P. teucrii, throw off their protective habit, and make 

 no tent, but simply feed under the leaves in their 

 usual fashion. Unlike P. teucrii, however, they are 

 very easy to rear, as, with a little care, nearly every 

 specimen produces the perfect insect. 



I found larvae feeding from time to time, from the 

 26th of May till the 20th of June, and by that time 

 the more forward specimens had begun to emerge. 



I have seen no indication of a second brood in the 

 year. (Charles Gr. Barrett, 11th October, 1871 ; 

 E.M.M., December, 1871, VIII, 156—158.) 



Pterophorus tephradactylus. 

 Plate CLXIV, fig. 3. 



In May of last year, 1880, and again in May of this 

 year, 1881, Mr. W. H. Grigg, of Bristol, kindly sent 

 me larvae of this species feeding on the leaves of 

 golden-rod. 



The larva is about half an inch in length, and of the 

 usual shape characteristic of the genus ; it is rather 

 flattened ventrally, but roofed upwards from the 

 spiracular region to the dorsal area, which is also 

 rather flattened ; the head is polished, about the same 

 width as the second, but narrower than the third 

 segment; the segmental divisions are clearly defined; 

 the tubercles are prominent, each of them emitting 

 several short hairs.
