NOTES ON NEW AND RARE BRITISH LEPIDOPTERA. 139 



ner's A. sudafaria ?ir]d foecata7'ia being considered by both 

 Standinger and Guenee as forms of ononaria. 



Description of J. ononaria. Alar expanse about 1". 

 Wings dull ochreous, entirely irrorated wieh atoms of a 

 brick-red colour, with an ill-defined and barely distinguish- 

 able central shade, formed by the accumulation of the afore- 

 said atoms, common to the four wings. The under surface 

 has a corresponding shade, which is more perceptible and of 

 a blackish hue. The hind-wings are clearer and of a more 

 yellowish tint than the fore- wings. The sexes are very much 

 alike. 



It is found in France (being common in the neighbour- 

 hood of M. Guenee's own residence, Chateaudun), and in 

 the north of Germany, in dry woods amongst Ononis spi- 

 7io.sa ; here in England it would appear to frequent Ononis 

 arvensis. 



Ononaria may be started up in its localities by trampling 

 through the Ononis. Its flight is dull and heavy. Ac- 

 cording to M. Guenee it appears in May, and then again in 

 July and August ; but Duponchel records it as emerging 

 all through the summer months. 



The larva is short, fusiform, fat, without protuberances of 

 any kind, and its whole body is furnished with a short stifl' 

 down ; in colour it is pale, dirty-green, with a darker dorsal 

 vessel, and paler, less distinctly expressed spiracular lines; it 

 feeds on Ononis in April and June, and is remarkably slug- 

 gish, showing no disposition to ramble from its food-plant, 

 for which reason it is, says M. Guenee, readily obtained in 

 France by cutting or mowing the tufts of *' rest-harrow,'* 

 (*' Bufjrane"). 



The chrysalis is enclosed in a cocoon amongst moss.
