.it when distinctly present, entirely brown 

 rithout any white : the hind wings are plain 



>wn with paler fringe : the head, thorax, 



id body are rather pale brown. 



The CARERPILLAR, according to Guenee, is of 



dingy white colour freckled with brown 

 spots ; the head is ferruginous and glabrous, 

 and the spiracles are black : it resides in. the 

 interior of the hollow stems of the common 

 reed (Arundo Phragmitcs), on which plant ex- 

 clusively it seems to feed. 



The MOTH appears on the wing in July, and 

 has been taken near "VVitham, in Essex, and 

 hi Hammersmith marshes. (The scientific 

 name is Nonagria yeminipuncta.) 



458. The Brown-veined Wainscot (Nonagria 

 Arundinetf). 



458. THE BROWN-VEINED WAINSCOT. The 

 antenna? are nearly simple in both sexes ; the 

 wings have the costa rather arched, the 

 very blunt, and the hind margin slightly 

 lied; their colour is ochreous-brown in some 

 specimens, plain brown iu others ; in the 

 former instances there is a darker median 

 longitudinal dash, and near the extremity of 

 this is an ocellated nearly circular spot, dark 

 brown in the centre, and surrounded with 

 paler brown : in the paler specimens the 

 wing-rays are spotted ; there are three rather 

 conspicuous but very small spots above the 

 ocellated spot, but nearer the base of the 

 wing, and there is also a hind-marginal series 

 of dark crescentic spots : the hind wings are 

 gray-brown and rather paler at the base; they 

 also have a marginal series of dark crescentic 

 spots : the head and thorax in the paler 

 specimens is ochreous-browii ; in. the darker 



specimens, dark brown ; the body is long, 

 slender, and tufted at its tip; its colour is 

 grayish-brown.

 red dorsal line (Treitschke). It feeds in the 

 stem of the common reed (Arundo Phrag- 

 mites)." Staintoris Manual, vol. i. p. 193. 



The MOTH appears on the wing in July, and 

 has been taken in the fens of Cambridgeshire. 

 (The scientific name is Nonagria Arundineti: 

 it is the Nonagria neurica of Doubleday's 

 List). 



Obs. The lower figure represents the 

 variety dissoluta of Treitschke : this is the 

 neurica of Hiibner, figs. 659 661, and the 

 Hessii of Boisduval. The upper figure is the 

 neurica of Treitschke. 



459. Fenn's Nonagria (Nonagria IreviUnea). 



459. FENN'S NONAGRIA. "Fore wings 

 rather sharply angulated at the junction of 

 the costal and hind apical margins ; brownish 

 ochreous, with numerous scattered black 

 scales; a sharply-defined short black dash 

 from the middle of the base ; a curved row of 

 small black dots reaches from the costa to the 

 inner margin beyond the middle; apical veins 

 [rays] conspicuously paler than the ground- 

 colour, apical margin unspotted; hind wings 

 gray, paler towards the base, a very indistinct 

 transverse row of black dots, rather beyond 

 the middle, uniform with those in the fore 

 wings." G. Fenn, in Entomologists Monthly 

 Magazine, vol. i. p. 107. 



The MOTH appears early in August : Mr. 

 Fenn, to whom we are indebted for a know- 

 ledge of the insect, and whose description I 

 have quoted, took a single specimen flying at 

 dusk among the great reed mace (Typha 

 latifolia), on the 4th of August, 1864: he has 

 most kindly lent me the insect to figure for
