82 HAUSTELLATA. — LEPIDOPTERA. 



Till witliin these few years one or two examples only of ,tliis 

 insect were known : they were captured, I believe, on the borders 

 of Ramsey-mere ; but many specimens have been taken recently 

 on the shores of Whittlesea and Yaxley meres, whence the insect 

 would appear to aifect marshy districts: the female seems to be 

 much rarer than the male. 



Sp. 2. venosa. Thorace alisque anticis canis, aut oclwaceis, his albo-venosis 



lineis tenuissimis fuscis ; posticis albis. (Exp. alar. 1 unc. 6 — 8 Kn.) 

 No. venosa. Borkhausen.—^i. venosa. Steph. Catal. part n. p. 102. iVb. 6351. 



Head and thorax pale hoary- white or ochraceous, the latter sometimes with a 

 faint dusky transverse hne before the middle; anterior wings also pale- 

 hoary or ochraceous, thickly sprinkled with minute black atoms, with a more 

 or less distinct dusky or black lineola from the base nearly to the midtUe, 

 and a faint one near the apex, and frequently two or three others towards 

 the hinder margin, running parallel with the nervures ; on the hinder margin 

 itself, towards the apex, are occasionally one or two black dots; the ciha 

 are pure white : posterior wings and abdomen immaculate white. 



Var. jS. Anterior wings without the longitudinal dark Uneolae. 



Var. y. Anterior wings ochraceous-ash, with the base of the costa hoary, and the 

 cilia ochraceous-brown ; the disc not irrorated with black, and the dark 

 lineolas wanting. 



Caterpillar very hairy, yellowish above, with spots and dots of rufous, fuscous, 

 and black, a yeUow lateral line interrupted with brown dots : — it feeds on 

 Carices: — the pupa is black-brown, and enclosed in a strong papyraceous 

 cocoon : — the imago appears about the middle of June. 



Apparently not very uncommon in the fenny districts of Hunting- 

 donshire and the north of Cambridgeshire, numerous examples 

 having been captured on the borders of Whittlesea-mere, and 

 one or two near Wisbeach. I am not aware of its having been 

 found in any other locality. 



Sp. 3. nervosa. Alls anticis siiblanceolatis cinereo-fuscis pallide striatis, posticis 

 cinereis venis fiiscesceiitibus. (Exp. alar. 1 unc. 3 — 4 Un.) 



No. nervosa. Wien. Verz. — Si. nervosa. Steph. Catal. pai-t ii. p. 102. No. 

 6352. 



Head, thorax, and abdomen immaculate hoary-white; anterior wings pale- 

 ashy- or hoary-brown, with paler or whitish longitudinal streaks following 

 the direction of the nervujres, which latter are fuscescent ; cUia the same ; 

 posterior wings pale cinereous, with minute darker atoms, the nervures 

 brownish. 



The caterpillar feeds on the elm : — the imago appears in June. 



Leucania pudornia is sometimes erroneously placed in collections for this 

 species.
