158 DRYMONJA CHAONIA. 



the cocoon of chaonia by the brownish-golden colour 

 of the silk lining and also by its larger size and greater 

 strength ; the pupa I measured was 13 mm. long, stout 

 in figure, swelling out widest at the abdomen, otherwise 

 cylindrical, the tail rounded, without a spike but with 

 two little bifid warts ; the colour deep mahogany-brown, 

 rather glossy. (J. H., 28, 12, 86.) 



Drymonia dodon^a. 

 Plate XXXIV, fig. 4. 



This larva was figured by Mr. Buckler September 

 9th and 12th, 1867, and he bred the moth June 12th, 

 1868 ; he figured it again August 12th, 1871. 



In 1857 and 1858 I found several pupae at the roots 

 of oak trees, and bred the moths in 1 858 and 1859, 

 from May 14th to June 3rd, but I never could find the 

 larva ; the food is always oak. 



Mr. Harwood tells me the larva has a superficial 

 resemblance to that of Lophopteryx carmelita, and that 

 there are two varieties, one with a yellow spiracular 

 line, the other with a reddish line ; the general colour is 

 pea- green. The cocoon I measured is of a toughish 

 fabric of silk, well covered with fine earth, about 20 

 mm. long and 8 mm. wide, regularly formed ; the pupa 

 is not so stout as that of chaonia, but is rather more 

 glossy. (J. H., 29, 12, 86.)

Mr. Buckler figured this species from poplar August 

 16th, 1860, and June 17th, 1867 ; he bred the moth 

 from the latter larva July 30th, apparently, therefore, 

 obtaining a second flight. The question of the double- 

 broodedness in England of several species of " Pro- 

 minents " was hotly debated some years since, when
