THE YOUNG 



NATURALIST. 



places where the reed mace (Typha latifolia) 

 grows. 



Aporophylla Australis is very nearly an 

 inch and a half in expanse of wing. The 

 fore wings are oblong, roof-shaped in repose; 

 grey ; darker along the costa, with fine, 

 black, longitudinal lines, one of which starts 

 from the middle of the base. Near the hind 

 margin is a row of wedge-shaped, dark spots. 

 The hind wings of the male are whitish ; of 

 the female dark greyish brown. The abdo- 

 men is crested at the base. It only occurs 

 on the south coast. 



Agrotis puta is smaller than any of the 

 commoner species of the genus. The fore 

 wings are greyish ochreous, blotched with 

 brown, and with an almost linear orbicular 

 stigma. 



Agrotis agatMna is about the same size as 

 the preceding. It occurs among heath in 

 the south. The fore wings-are reddish grey. 

 Both the orbicular and the reniform stig- 

 mata are pale — the former conspicuously 

 so, — and are placed on a broad black line, 

 which commences at the reniform stigma, 

 and after continuing, just wide enough to 

 enclose the stigmata, until a short distance 

 beyond the orbicular stigma, suddenly nar- 

 rows and terminates in a point nearly at 

 the base of the wing. The wings of both 

 species, like those of the Noctuidas in gen- 

 eral, are flat when the insect is in repose 

 and cross one another a little. 



Cymatopliora dilutee is smaller than any 

 other of the genus, the fore wings being 

 about an inch and a quarter in expanse, 

 pale grey in colour, with two straight brown 

 bands. The hind wings are whitish ochre- 

 ous. It is common at sugar in many places 

 in August and September. 



Agrotis obelisca sometimes expands an 

 inch and a half, but in general is rather 

 less. The fore wings are brownish grey, 

 with a pale ochreous streak along the costa. 



There is a dark spot between the stigmata 

 and another before the orbicular stigma. 

 There is also a deep brown streak from the 

 middle of the base. A. lunigera is about the 

 same size. It has a conspicuously pale grey 

 orbicular stigma ; the ground colour of the 

 wings is grey, shaded with reddish brown ; 

 the reniform stigma is reddish brown, out- 

 lined with black ; the hind wings are white, 

 and in the females have a grey margin, and 

 also veins and lunule of the same colour. 



I shall say but little about the larva; of 

 the noctuina this month, as I shall have so 

 much to say about them in September. I 

 will merely remind my readers of the fol- 

 lowing : — 



SPECIES. COLOUR. FOOD PLANT. 



O. or Yellowish green Poplar 



A.porphyrcea Reddish orange Heath 



D. carpophaga Dark grey Bladder campion 



D. cucubali Orange & yellow Do. 



H. dysodea Reddish green Lettuce flower 



X. lithorhiza Ochreous grey Honeysuckle 



G. chamomillcB Yellow Chamomile 



H. marginata Green Rest harrow 



I can speak but very briefly of the 



Other Moths for August. 



I will, however, just mention the pale brown 

 Phycis roborella ; the ochreous Cr ambus 

 inquinitdluS) with several whitish veins ; 

 the narrow-winged pale brown Phlaodes 

 immundana, the second brood of which may 

 perhaps be beaten out of birch ; the whitish 

 and reddish ochreous Peroncsa permutana, 

 to be looked for among Burnet roses ; the 

 fuscous Depressaria clicerophylella, to be 

 looked for where wild chervil grows ; the 

 dark brown Depressaria badiella ; and the 

 grey plume Pterophorus lithodactylus. The 

 moths of the genus Litlwcolletis, all of which 

 come out for the second time in August, are 

 already described and beautifully figured in 

 several places in the present volume, and I 

 have no need to say more about them.
