large numbers are destroyed when the hops 

 are gathered. The larva is very peculiar, 

 having a long white blotch on the back, 

 exactly as if a drop of white paint had 

 fallen on it, and was still wet and shining. 

 28. LIMENITIES SIBYLLA. 



The White Butterfly. — A butterfly 

 that only occurs in the South of England, 

 scarcely reaching the midlands. It has 

 never been recorded from Scotland or Ire- 

 land, It is a wood insect, and is particularly 

 noticed for its graceful flight. The larva is 

 thickest in the middle, rather resembling in 

 shape the common black snail Arion atey, 

 but bluish-green in colour. The pupa is 

 very much angulated, and has two peculiar 

 ear-like projections on the head. 



29. APATURA IRIS. 



The Purple Emperor. — The desire to 

 possess this monarch of the woods is always 

 strong with young Entomologists. It is a 

 butterfly that appears in July, and is found 

 in extensive woods in the South and South- 

 east of England. It is said only to occur in 

 oak woods, though the larva feeds on pop- 

 lar and sallow. It disports itself about the 

 tops of the loftiest trees, and is very diffi- 

 cult to capture. But it is attracted by 

 carrion, or striking puddles, and it is curious 

 enough to follow down a sod or similar 

 article thrown up to the tree tops where it 

 flies, and may someti:ncs be taken in this 

 way. The larva, similar in shape to the 

 last, is pale green, with a yellow line 

 at the sides. It hybernates quite small, and 

 is full fed in May or June. 



30. ARGE GALATHEA. 

 The Marbled White. This butterfly 

 is also very appropriately called " The Half 

 Mourner " in some places. It only occurs 

 in England, where it extends as far north as 

 Yorkshire. It frequents rough pastures, and 

 is always very local, though generally abun- 

 dant where it occurs, swarming perhaps in 

 one field and nowhere else near. The 

 larvae hybernates quite small, and feeds up 



in spring. They are smallest at each ex- 

 tremity, green in colour and feed on grasses. 



31. EREBIA EPIPHRON. 



The Mountain Ringlet. — The only 

 English locality are hills, in what is called 

 the Lake district. In Ireland, it is found at 

 Craigh Patrick, near Westport ; and in 

 Scotland there are several known localities 

 for it, in Perthshire, Invernesshire, &c. It 

 is not at all improbable that the Scotch and 

 English insects may ultimately prove to be 

 different species. They are very different 

 in appearance, much more so than some 

 species, that are recognised as distinct. The 

 larva is scarcely known, but feeds on grasses 

 or small jfmtco, on the mountain sides. The 

 butterfly is on the wing before the end of 

 June, and those who go for it should get it 

 as soon as possible, as it is so delicate that 

 it soon looks worn. Perhaps this is better 

 known as " Cassiope." 



32. EREBIA MEDEA. 



The Scotch Argus, — Better known 

 among collectors as Blandina. In the North 

 of England it is very abundant in the few 

 places where it occurs, but extremely local. 

 If you go to its haunts, you may take it by 

 hundreds, but might be within a few yards 

 of where it was plentiful and never see it. 

 It frequents open places in woods, grassy 

 banks, &c. The larva tapers slightly to 

 each end, is pale stone colour, with longi- 

 tudinal stripes. The butterfly appears in 

 the last week in July, and should be looked 

 for at once, as it is easily damaged. The 

 larva hybernates to feed up in spring. 



33. CCENONYMPHA PAMPHILUS. 



The Small Heath. — A most abundant 

 little butterfly, occurring freely everywhere 

 from May to August. Tliere seems to be a 

 succession of broods, ami the larva, which 

 is green, hybernates in all stages of growth. 

 It foeils on grass.
