6 DIANTH^OIA ALBIMACULA. 



teristic is the absence of the slanting streaks or chevrons 

 which they so generally have. 



The pupa is little more than five-eighths of an inch 

 long, stout in proportion, the wing-, antennae-, and 

 trunk-cases projecting in a blunt point over the abdo- 

 men, which tapers off gradually ; the abdominal rings 

 are partly granulous ; the colour of the thorax and 

 wing-cases is deep reddish-brown, the abdomen dark 

 brown. 



M. Gruenee has observed of the larva of D. albimacula 

 that " in a manner it resembles that of D. capsincola, 

 and when they are together on the same plant they 

 afford fine exercise for the eyes to distinguish them. 



"It is found upon Silene nutans, and sometimes, but 

 much more rarely, on Silene inflata. In captivity it 

 accommodates itself well to these two plants, also to 

 Lychnis dioica. 



" This caterpillar is not rare where Silene nutans 

 grows, that is to say in the arid and hilly places of 

 certain woods." (W. B., May 11th, 1874; E.M.M., 

 June, 1874, XI, 16.)

Plate LXXXVII, fig. 3. 



Towards the end of June, 1867, I received two 

 small larvsD of this species, scarcely half an inch long, 

 from Mr. C. S. Gregson, who sent with them a couple 

 of flowers and a leaf or two of Silene maritima, and 

 instructions to feed them on the flowers and leaves of 

 that plant. Perhaps for want of sufficient air in their 

 small box during the journey in hot weather, one 

 arrived in a dying state, and though much attention 

 was paid to the survivor, that also soon sickened and 

 died. 



I noted that this little larva was of a grey colour,
