240 HAUSTELLATA. — LEPIDOPTERA. 



ascending and slightly incurved, but the entire habit of the insects 

 both in the imago and larva states is dissimilar : in these insects the 

 anterior wings, which are somewhat obliquely truncate on the hinder 

 margin, are adorned with large blotches and dots of black on a pale 

 (usually white) ground, and the larvae do not reside in communities, 

 but are solitary : I, therefore, adhere to my former opinion, in sepa- 

 rating the two genera, though, as Hlibner had previously named and 

 characterized the present, I have reverted to his name. 



A. Anterior wings with confluent black spots, forming a longitudinal streak 

 from the base nearly, or entirely, to the apex : — Anesychia, H'libner. 



Sp. 1. Echiella. AUs anticis fuscis, vitta communi dentata alba, thorace niveo 



punctis atris, abdomine luteo. (Exp. Alar. 12 — 13 lin.) 

 Ti. Echiella. Wien. Verz.—Me. Echiella. Steph. Catal. ii. 202. No. 7266.— 



Yp. Echiella. Curtis, v. ix. pi. 412,/.* 



Anterior wings deep fuscous on the costa, excepting the apex, which is ashy, 

 the inner margin whitish or cream-colour, the fuscous portion within 

 sinuated, and having about three conspicuous projecting blackish dots ; on 

 the extreme hinder margin, extending a little along the costa, is a row of 

 minute black dots ; posterior wings whitish, with the apex ashy ; abdomen 

 luteous ; thorax whitish, with about six black dots. 



Caterpillar black, with a whitish lateral stripe, and a yellowish spot on the 

 first and last segment: it feeds on the Viper-grass {Echium vulgare). 



The beautiful pair of this species in the British Museum was 

 taken near Aylesbury in Buckinghamshire, in June, I believe in 181C; 

 not at Dover, as stated by Mr. Curtis; but the specimen in my 

 collection was found there many years previously. 



Sp. 2. pusiella. Plate 39. f. 3. — AUs anticis albis, punctis vittoque media 

 maculisque rhombeis contiguis atiis. (Exp. Alar. 13 — 15 lin.) 



Ph. Ti. pusiella. Linnl—Me. pusiella. Steph. Catal. ii. 203. N'o. 7267.— 

 Yp. pusiella. Curtis, v. ix.pl. 412,/.* 



Anterior wings white or cream-colour, with an irregular waved black stripe, 

 extending from the base to near the apex, composed, as it were, of rhomboid 

 black spots, with two detached round black dots near the base on the inner 

 margin, and one on the outer; also a large rhombic spot about the middle 

 of the costa, and two or three rather minute dots towards the apex of the 

 costa, exclusively of a row of black dots which commences from the rhomboid 

 costal spot and terminates on the hinder angle : cilia white, with a dusky 

 dot on the anterior angle : posterior wings ashy-brown and glossy, with an 

 interrupted brownish line on the extreme edge; cilia white, with a dusky 

 spot at the apical angle : thorax with seven black dots.
