20 HAUSTELLATA. — LEPIDOPTERA. 



a pale transverse undulated striga, and a little behind the middle anotlie?, 

 placed very obliquely, and crenated exteriorly; beyond this, near the hinder 

 margin, is an undulated obscure ochraceous striga, bordered interiorly with 

 rosy-red: the anterior stigma is round or ovate, white or yellowish, and is 

 connected by a concolorous streak to the posterior one, which is large, placed 

 very obliquely, and in general tinted with rosy-ochraceous within ; nervures 

 sometimes ochraceous: abdomen and posterior wings fuscous, the latter a 

 little tinted with rosy : cilia rosy at the base, the apex pale. 

 Caterpillar bright green, with a dorsal and two lateral lines white, the lower one 

 on each side tinted with ochraceous or ferruginous:— it feeds on the Pinus 

 sylvestris, and other firs r is full grown towards the end of June : the imago 

 appears at the end of March. 



The mere accident of discovering this beautiful species to inhabit 

 Britain, I believe, fell to me, having beaten a chance specimen out 

 of an old fir tree at Hertford, in the April of 1810, which remained 

 unique for three or four years. In the spring of 1815 my friend 

 J. Scales, Esq. took the insect in considerable plenty near Beacham- 

 well, in Norfolk, flying about the blossoms of the black thorn, in 

 the vicinity of some pines, and to him I am indebted for part of 

 my present series ; since that period the insect has been taken in 

 the larva state in abundance at Birch-wood, and near Ripley, though 

 happily without creating the havoc, which frequently accompanies 

 its appearance on the continent. " Matlock." — Bev. F. IV. Hope.

Genus CXVII. — Actebia* mihi. 



Palpi short, robust, porrected obliquely, densely clothed with compact scales ; 

 the terminal joint exposed, subrhombic; the two basal joints nearly of equal 

 length and stoutness, the first curved, the second shuttle-shaped, the terminal 

 slender, elongate-ovate : maxillce elongate. Antennce elongate, slender, pubes- 

 cent beneath, ciliated on each side in the males : the basal joint large and 

 squamose : head small, with a dense frontal crest : eyes large, globose, naked : 

 thorax sHghtly crested posteriorly : abdomen elongate, somewhat depressed, 

 a Httle pubescent at the base, slightly carinated in the males, with a small 

 anal tuft; stouter in the females: wings deflexed during repose; anterior 

 very narrow, linear, entire, glossy ; posterior ovate-triangular, entire. 



Caterpillar naked, smooth : pupa subterranean. 



Actebia may be at once distinguished from the preceding genus, 

 with which it is associated by Ochsenheimer and Treitschke, by the 

 comparative bulk of its head, and smallness of its thorax, the latter 

 not being pubescent, and very slightly crested ; the anterior wings
