HAUSTELI.ATA. — LEPIDOPTERA. 



Smaller than the foregoing, of a different colour, and the strigse dissimilarly 

 placed. 



Found in woods with the preceding species. " Newcastle." — 

 G Walks, Esq. 



Genus CCXXXVII. — Pcecilophasia * mihi. 



Palpi very short, slender, remote, acute, sparingly clothed with short scales^ 

 triarticulate ; the basal joint curved, attenuated j second subovate, short ; ter- 

 minal elongate-ovate : maxillce long. Antennoe short, simple in both sexes, a 

 little pubescent within in the males : head small ; forehead slightly prominent : 

 eyes large, globose : thorax slender : wings somewhat expanded during repose, 

 the hinder margins entire; of the anterior nearly straight, of the posterior a 

 little emarginated towards the costa ; all bordered with a dark sinuous fimbria 

 upon a white ground, the disc without the usual transverse striga or a central 

 dot: abdomen slender and carinated above in the males, rather stout and 

 acute in the females : legs rather short; posterior tihice incrassated and slightly 

 ciliated in the males, with two pair of short spurs ; more slender, with longer 

 spurs, in the females : posterior tarsi slightly abbreviated in the males. 



The posterior tibise are also slightly thickened in this genus, but, 

 unlike those of the two foregoing, they possess two pair of short 

 spurs each in both sexes : their wings are of a pale hue, with a 

 sinuated and interrupted dark border, excepting on the costa of the 

 posterior ; but they do not possess either strigae or a central dot, so 

 usual among the Geometridse. One species only is known, which 

 is extremely variable ; its affinity to the genus Abraxas I am at a 

 loss to conceive.

Head, thorax, and abdomen black ; base of the anterior wings with a broad oval 

 black spot, and behind the middle of the costa a second smaller one, nearly 

 united to the first; on the hinder margin is also a broad sinuated black border 

 common to all the wings, and the cilia are likewise black; in the centre of the 

 wings is generally a common interrupted black fascia.
