terfly. 
Meuir£a ARTEMIS (the Greasy Fritillary, No. 1) is perhaps the commonest of the genus, 
but is nevertheless very local. It is a very distinct species, two irregular bands of palish buff 
between the bands of black rendering it distinguishable at a glance from either Cinzia or Athalia. 
The under side (No. 2) is very similar to that of Athalia, but may be at once recognised by the 
paler character of all the markings, and the presence of a regular series of black spots circled 
with buff (in the broad band near the edge of the hind wings), which are absent in A¢thalia. 
The Caterpillar (No. 3) feeds on the Devil’s-bit Scabious, and on both the Plantains. Ac- 
cording to the graphic account of our good old English Aurelian, Moses Harris, the Caterpillar 
when full grown, draws together two or more blades of grass, fastening them at the top with a 
web, and suspending itself in the centre beneath ; but as I have never seen the Caterpillar or 
Chrysalis when suspended in this manner, I have merely represented it as attached by the tail 
in the usual way. 
The Chrysalis (No. 4) is of a pale flesh-colour, prettily ornamented with dark and regularly 
disposed spots. The Caterpillars, like those of IZ. Cinzia, are hatched in the autumn, and pass 
the winter in a similar manner. They become full grown in April, and the perfect butterfly 
appears in the following May or June. It is generally found in marshy places and has hence 
been termed by some entomologists the Marsh Fritillary. Specimens of Jf Artemis vary con- 
siderably in the intensity of their markings, some of the varieties having been mistaken for 
M. Cinwia. Near Brighton, and also near Bristol, this species has been recently taken in great 
abundance ; and Carlisle, Charnwood Forest, and Weston-super-Mare are also cited by Mr. 
Stainton as localities in which it is often captured, as well as York, Winchester, and Worcester. 
Melitea Dia, a closely allied species, was formerly found in our English catalogues as a native 
species, on the strength of specimens taken at Sutton Park, near Birmingham, and at Alderly in 
Cheshire, but it is now omitted. It is the Argynnis Dia of Hiibner and Ochsenheimer. 
The third family of Butterflies is that termed the Erycinidw, represented in British Collec- 
tions by a solitary European species, Nemeobius Lucina. In this family the males have only four 
perfect feet, like those of the Argynnidi, but the females have all six feet perfect. The Cater- 
pillars are onisciform, like those of the Lyccenide, to which family, therefore, this genus, in its 
present position, forms an appropriate link. 
The genus Nemeobivs has the antenne slender and the club short ; the wings are tawny ; 
the fore wings with the costa and hind margins straight, and the apex hardly rounded. The
