Genus LXVIII. — Eutiiemonia * ?/z/Ai. 



Palpi porrecteJj moderate, slightly hairy, triarticulate ; the basal joint shorter 

 than the second, the terminal rather slender : vmxilUe short. Antennae rather 

 shorty slender, bipectinated in the males, serrated in the females : head small, 

 pilose: tliorax and abdomen rather slender; the former hairy, the latter with 

 a small tuft at the apex, and annulated : wings deflexed, densely squamous, 

 trigonate: legs rather slender, the anterior with a compressed lobe on the 

 inner edge, the posterior with spines at the apex : females smaller than males. 

 Larva with short, closely set fascicles of hair: pupa rather elongate, v/ith a 

 spine at the apex. 



Unless Eutliemonia be divided from Arctia, the latter genus f 

 should be restored to its artificial state, as left by Ochsenheimer, a 

 retrograde movement which woidd tend rather to create error than 

 to advance knowledge. The present genus differs very considerably 

 from Arctia in its habit, and the proportions of the joints of the 

 palpi are very dissimilar.

 Catal No. 6017. 



Male, with the thorax and anterior wings pale luteous, the costa towards the 

 apex, the inner margin and cilia bright sanguineous, a fuscous lunulated spot 

 in the middle more or less edged with sanguineous: posterior wings and 

 abdomen yellowish- v.'hite, the former with a dusky lunate spot on the disc and a 

 marginal fimbria of the same colour ; cilia sanguineous : shaft of the antennae 

 and legs rufescent, radii of the former dusky. Female with the antennae, head, 

 thorax, and anterior wings, rufo-fulvous, the margins of the latter, nervures, 

 and central lunule, bright sanguineous ; the posterior wings fulvous, with the 

 base, an ovate spot near the centre, and the margin, dull black : the abdomen 

 black, with the edges of the segments pale fulvous. The marginal fascia in 

 the posterior wings varies exceedingly; in some specimens it is nearly obli- 

 terated, in others interrupted by pale yellowish veins, and in some it forms 

 a broad border, and the base of the wing is dusky. 



Caterpillar dusky, with yellow lateral spots, and dull orange hair : it feeds on 

 grasses, the plantain, scabious, hounds-tongue, &c. : changes in May to a red- 

 dish-brown pupa, in a web on the ground : the imago appears in June. 



Far from uncommon on the warren and heathy places about 

 Coombe-wood : the female, however, is rarely met M'ith, owing to her 

 sluggishness, and being generally concealed at the roots of plants :
