264 HAUSTELLATA. — LEPIDOPTERA. 



sexes, slightly pubescent within in the males : head short ; forehead with a 

 conical fascicle of scales : eyes globose, prominent : thorax slender, simple : 

 wings placed in a triangle during repose ; all with the hinder margin slightly 

 waved, and marked with numerous dark flexuous lines on a flavescent ground 

 colour : abdomen short, somewhat cylindrical obtuse, with a small tuft at the 

 apex, rather stoutest in the females : legs simple. Larva with 10 legs, ob- 

 scurely spotted or lineated, not tuberculate. 



Camptogramma not only differs from the preceding genus by the 

 dissimilarity in the structure of the palpi, but in other points, and 

 may be readily known by the flavescent or luteous hues of its ample 

 wings, which are all strigated transversely with darker lines inter- 

 mixed with whitish, and have their hinder margins sinuated. 



Sp. 1. bilineata. Alls luteis, undulis obsoletis numerosis ohscurioribus fasciiique 

 duplicis medio anticarum fused externe sinuatd alboque marginatd. (Exp. 

 alar. 1 unc. 1—4 lin.) 



Ph. Ge. bilineata. Linne. — Don. viii. pi. 287. f. 3.— N. G. bilineata. Steph. 

 Catal. part ii. p. 140. No. 6615. 



Wings luteous, with numerous obsolete darker, or testaceous waved strigae, the 

 anterior with a broad unsolid fascia, having its margin suffused with fuscous 

 and edged with white, and considerably sinuated exteriorly, a whitish striga 

 towards the base, and near the hinder margin a pale waved one_, more or less 

 distinct, and sometimes clouded with fuscous within ; cilia clouded with pale 

 fuscous : posterior wings rather tawny, with one or more whitish striga inter- 

 mixed with the darker ones. 



Extremely variable ; some examples being destitute of the fuscous margins to 

 the central fascia : others wanting the striga on the posterior margin, and 

 some having the hinder margin entirely fuscous: in some cases the extreme 

 margins of all the wings have a deep black line: the cilia are sometimes 

 totally immaculate. 



Caterpillar greenish, sometimes with faint white streaks, or nearly immaculate : 

 it feeds on the Lychnis Dioica. 



Very common ; occurring copiously in every hedge near London 

 during the end of June and beginning of July : and I believe in 

 other parts. " York." — W. C. Hewitson, Esq. " Northumber-
