BRITISH MOTHS. 



palpi are very decidedly curved upwards, the 

 terminal joint small and pointed ; the antennae 

 are simple: the fore wings are very slightly 

 arched on the costa, blunt at the tip, and 

 scalloped at the anal angle ; their colour is 

 cinnamon-brown, mottled and marbled with 

 darker brown; the discoidal spots are pale 

 cinnamon-brown, the reniform assuming the 

 appearance of a figure of eight, the two median 

 areas thereof being black spots; the orbicular 

 has one such black spot, and there is a very 

 similar cinnamon-brown and black central 

 mark between the orbicular and the costal 

 margin ; there are four gray transverse lines, 

 all of which are inconspicuous ; the first is 

 short and very slender, and it is situated near 

 the base of the wing; the second is also slender, 

 and situated before the orbicular; the third is 

 beyond the orbicular, is much bent outwards 

 in the middle, and expands into a griiy cloud 

 on the costal margin ; the fourth is parallel with 

 the hind margin, and expands into a gray cloud 

 on the costal margin : the hind wings are black, 

 but slightly paler towards the base, and the 

 pale portion contains a dark crescentic discoidal 

 spot ; the fringe is orange : the head and 

 thorax are dull orange-brown ; the body is 

 blackish-brown, with delicate orange rings: 

 the disk of the under surface of all the wings 

 is black, with a broad orange margin. 



The CATERPILLAR is described by Guenee 

 as having the head of a pale green-colour, 

 the body much attenuated anteriorly and 

 flattened below; the segments distinctly 

 divided and somewhat rhoinboidal in form : 

 the colour is a beautiful glaucous-green, with 

 a broad and continuous medio-dorsal stripe of 

 a pure white ; there is also a sub-dorsal and a 

 lateral stripe, both of which are narrower 

 than the medio-dorsal, but like that, unin- 

 terrupted and pure white; the lateral stripe is 

 below the spiracles, which are black, but 

 encircled with white : the legs and claspers 

 are pale green: it feeds on the elm (Ulnms 

 campestris), the leaves of which it binds care- 

 lessly together with a few silken threads: the 

 CHRYSALIS is short and covered with a violet- 

 coloured bloom. 



The MOTH appears on the wing in July, and 



has occurred in several English counties. Mr. 

 Reading gives a number of Devonshire loca- 

 lities, and it seems not to be uncommon in 

 Somersetshire, Dorsetshire, Isle of Wight, 

 Kent, Essex, Suffolk, Norfolk, Hereford, 

 Worcester, Shropshire, Derbyshire, and York- 

 shire, and Mr. Birchall, met with it at Powers- 

 court, in Ireland. (The scientific name is 

 Cosmla affinis.) 



613. The Dnsky Sallow (Ercmolia ochroleuca). 



G13. THE DUSKY SALLOW. The palpi are 

 porrected, the second joint slender but scaly, 

 the scales almost entirely concealing the 

 very small terminal joint; the antennae of the 

 male are ciliated with short hairs, each sepa- 

 rate hair being recurved, those of the female 

 are simple : the fore wings are straight on the 

 costa, rounded at the tip, and waved on the 

 hind margin ; their colour is dull ochreous- 

 brown with darker brown markings ; the 

 discoidal spots are scarcely to be distinguished ; 

 the reniform is contained in, and confused 

 with, a pale costal blotch ; the orbicular is 

 contained in, and confused with, a larger and 

 darker costal blotch nearer the base of the 

 wing; opposite this latter is a smaller dark 

 blotch near the middle of the inner margin ; 

 there is a series of dark crescentic spots on 

 the waved hind margin of the wing, and the 

 fringe contains two series of corresponding 

 spots : the hind wings have much the same 

 colour as the fore wings, but the paler tint is 

 confined to the base and fringe, the darker 

 tint forming a broad but vague hind-marginal 

 band: the head, thorax, and body are pale 

 ochreous-brown, the head and front of the 

 thorax being very pale ochreous. 



The CATERPILLAR is described by Guenee as 

 having a large head of a pale red-colour, and 

 an elongate cylindrical body, with the usual
