taken several times. I believe it has also occurred in the neigh- 

 bourhood of Woodford or Epping Forest. 



Sp. 3. flava. Alis 07?inihii.s r/ndiquejiavis imrnaculatis. (Exp. alar. 1 unc. 4. — 6

Antennae luteous : head, thorax, and abdomen pale ochraceous : eyes black : 

 anterior wings above pale ochraceous-yeUow or straw-colour; beneath paler, 

 immaculate ; posterior wings whitish yellow : cilia of all pale luteous ; legs 

 pale yeUow. 



Like the two preceding species, this is also very uncommon : it 

 has been taken near Birch-wood and at Darenth : and I have one 

 specimen, which was caught near Brockenhurst in the New Forest. 



Sp. 4. gilveola } Alisjlavescentibu^, anticis suhtus cinerascentibus, posticis iitrin- 



qve pallidis. (Exp. alar. 1 unc. 4 — 6 lin.)

Size of the last : antennae, head, thorax, and apex of the abdomen bright luteous ; 

 rest of the abdomen cinerascent : anterior wings pale luteous-yellow, with the 

 disc slightly suffused with cinereous beneath, with a large cinerascent patch 

 on the disc, the margins luteous : posterior wings on both sides pale yellow, 

 tinged with cinereous : legs deep luteous : eyes black. 



I have a fine pair of this apparently very rare species, which 

 were captured either at Birch or Darenth-woods, and are the only 

 indigenous examples that have hitherto come under my notice.

 found about May, the imago appearing at the end of July or beginning of 

 August. The pupa is reddish-brown. 



The most abundant species of the genus ; occurring in plenty in 

 v.oods and shady lanes throughout the metropolitan district, and
