ing the grain. Mons. Latreille, who notices this in his Histoire 

 Naturelle, says that he was unable to make out the species 

 from the imperfect state of the specimens submitted for his 

 examination. 



1. CE. Oliviella Fab.— MmuleWa Hiib. Tin.pl. 32. f. 222. 



Black with an orange tint; antennae metallic-purple, 

 with 6 or 7 articulations towards the apex white, the 

 scales 'elongated on the outside as far as the middle 

 in the males; maxillae and palpi ochreous; head cu- 

 preous; thorax with a yellow stripe on each side: 

 superior wings, beyond the middle, sprinkled with 

 minute yellow scales ; at the base is a cordate yellow 

 spot with a chalybeous stripe on the superior margin, 

 and a transverse striga beyond it of the same metallic 

 tint ; across the centre is a yellow fascia with a lunu- 

 late chalybeous spot beyond it touching the costa. 

 This beautiful species I find the middle of June in the Re- 

 gent's Park, flying about in the sunshine in the morning, and 

 setding on the pales. 



2. GE. sulphurella Fab. — Curt. Brit. Fnt. pi. ^OS. female. 



Male, blackish-purple; antennae shining blue-black, 

 with 3 of the articulations towards the apex white : 

 palpi, maxillae, and sides of the head ochreous; 

 thorax with a yellow stripe down each side ; anterior 

 wings sprinkled with minute yellow scales, with a 

 yellow costal stripe and sometimes an obscure one 

 along the middle, and a triangular yellow spot near 

 the posterior angle ; inferior wings orange ochre, a 

 small portion at the base, the superior margin, the 

 apex and the cilia blackish. 



Female, with the superior wing variegated with deep 

 dull blue, the costal and central yellow lines very 

 distinct, with a yellow spot on the costa opposite the 

 posterior angle. Abdomen with the margins of the 

 segments ochreous. 



Obs. The outline figure shows a male at rest of the 

 natural size. 

 Fabricius says this species inhabits old oak-wood, and that 

 the larva is three years before the metamorphosis is completed. 

 The Caterpillars were found alive at Christmas under the 

 bark of a dead tree at Fulham by C. J. Thompson, Esq. ; they 

 appear to feed on the inner bark, and were forming cases like 

 the Tineae. The Moth occurs in great abundance, flying about 

 and resting upon the paling of the Regent's Park, sometimes 

 as early as the end of April, but this year I did not see any 

 till the 2nd of May. 



The Plant is Ranunculus bulbosus (Bulbous Crowfoot).
