colour of the wings would readily distinguish it, and from both the small transverse 

 dark streaks on the inner margin is a certain point of difference. 



This species has been taken by Mr. Bedell on fences near Camberwell, and by Mr. 

 Sircom among oaks near Brislington, in June. It is apparently rare. Zeller says of 

 it, " As yet I have only taken this species in a thicket near Glogau, composed of sloe, 

 oak and aspen bushes, on- the 17th and 18th of June, 1834. Since then I have taken 

 only a wasted male, July 24th, 1842. It feeds probably on blackthorn, like tetrapo- 

 della, and as it flies with that species it is readily overlooked."

" One of the smallest species : most like retinella ; however it has much darker 

 brown annulated antennae, and on the anterior wings the small streaks are thickest on 

 the margins, and on the inner margin two appear from their dark colouring as spots : 

 with retinella most of the streaks are congregated on the disk behind the middle of the 

 wing, and neither on the inner margin nor on the costa do any appear as spots. 



" Head and thorax snow-white; the hairs on the head reach nearly to the end of 

 the basal joint of the brown and white annulated antennas. Face shining. Palpi as 

 long as the face, whitish. Feet satiny-whitish ; the fore feet with the upper side of 

 the tibiae and tarsi brown. Abdomen whitish gray, paler beneath. 



" Anterior wings rather broad, shining white, almost snow-white, with numerous 

 undulating, short, transverse streaks, of a yellowish brown colour, almost united to- 

 gether like net-work, which appear darkest and most distinct on the costa. On the 

 inner margin there generally appear, as spots, one in the middle and another thicker 

 at the anal angle, and sometimes even another at the lower half of the hinder margin. 

 At the apex of the wing some black atoms unite, and form a dot or short streak (like 

 a trefoil leaf, as shown in F-v-R.'s figure, it does not appear in any of my fifteen spe- 

 cimens, of which one came from F-v-R. himself). The cilia are yellowish brown at 

 the apex of the wing, always paler further towards the anal angle ; still paler on the 

 costa. 



" Under-side yellowish brown, with faint light marks. 



" Posterior wings rather broad, pale gray, with a faint pearly gloss. 



" Fundella occurs in Bohemia, at Reichstadt; in Silesia, in mountainous districts 

 (at Probsthainer Spitzberg in June, at Reinerz in July) ; in Prussia, at Dantzig ; in 

 Livonia, at Kohenhusen, abundant. It is beaten from the boughs of pines, on which 

 doubtless the larva feeds. Near Glogau it has not yet occurred, and appears — from 

 the scarceness of these trees in our woods here — not indigenous ; the statement in 

 F-v-R. and Tr. rests upon a mistake with retinella." And I would add that Dupon- 

 chel's figure appears to me to represent retinella. 



I have not yet been able to meet with a British specimen of this insect. I thought 

 at the time I began this paper that there were two specimens in Mr. Desvignes' rich 

 collection, but on a minute examination of the individuals in question I am satisfied 

 that they are only retinella ; at the same time I think it extremely probable that this
