H AUSTELL ATA. — LEPIDOPTERA. 



Anterior wings varied or clouded on the costa with black and fuscous, with 

 scattered darker dots and whitish spots ; the inner margin nearly to the 

 apex snowy white, also with a few black dots, and a larger spot of the same 

 colour at the base : posterior wings black or brown : head and thorax snow 

 white, with black spots. 



The caterpillar robust, brownish, with black head and small white dots: it 

 feeds on various species of willow : the imago appears towards the end 

 of July or the beginning of August. 



Not common; found in Battersea-fields, and in the vicinity of 

 Charlton and Hertford ; likewise in other parts of the country. 



Genus CCLXXXI. — Spilonota* mihi. 



Palpi short, porrected nearly horizontally, subclavate, densely clothed with 

 elongate compact scales, the apical joint not slender, exposed : maxillw 

 short. Antenna simple in both sexes, slightly pubescent within in the males : 

 head small, with a tuft of scales between the antemiise: eyes small, globose : 

 thorax subovate, not crested behind : wings deflexed during repose ; anterior 

 rather narrow, rounded behind, the extreme costal apex with a small circular 

 mark, colours generally dark on the base and costa, the inner margin with a 

 white blotch in the middle, and sometimes a second ; posterior ovate-trian- 

 gular, dark : abdomen rather short, stoutish, with a small tuft at the apex in 

 the males, obtuse in the females, and faintly tufted : legs short, posterior 

 longest. 



The species of this pretty genus are all characterized by having the 

 wings dark at the base and apex, and mostly also on the costa, with a 

 more or less extensive conspicuous white blotch in the middle of the 

 inner margin, but they differ from Pseudotomia, which also possesses 

 an internal (or dorsal) blotch by being deficient of the false cleft on 

 the hinder margin of the anterior wings, which forms so conspicuous a 

 character in those insects, and the dorsal blotch in them is rarely 

 white, being usually of a yellowish or golden tint : the wings are also 

 of dissimilar form, being narrower in proportion to their length than in 

 the Pseudotomiae. 



A. Anterior wings with a solid black fascia at the base, the apex pale, with 

 dark clouds or spots, costa sometimes dark, centre of inner margin white. 



a. Anterior wings broad, the basal fascia straight, and placed obliquelij : —
