GEOMETfllD.E. — HEMEROPHILA. 189 



Genus CLXXXVI. — Hemerophila *, mihi. 



Palpi short, porrected obliquely, densely squamous, subclavate, obtuse, the 

 terminal joint scarcely projecting beyond the scales; triarticulate, the basal 

 joint stout, slightly curved, the second elongate, subcylindric, the third placed 

 obliquely, minute, subacuminate : maxillce short. Antennw rather long ; in the 

 males each joint, excepting at the apex, producing on each side a short, 

 obliquely placed, deflexed, ciliated branch, decreasing in length towards the 

 tip, the terminal joints distinctly serrated within, with the extreme tip acute 

 and recurved ; in the females simple, obsoletely serrate within : head densely 

 squamous between the eyes : thorax slender, velvety : wings expanded during 

 repose ; the anterior with dark strigae, placed very obliquely on an ochraceous 

 ground, and with their hinder margin obsoletely angulated in the middle, and 

 obscurely indented ; posterior rounded and deeply indented : abdomen slender, 

 acute in the females. 



The form and colour of the wings, and the disposition of the 

 strigae thereon, point out the pretensions of this genus to be sepa- 

 rated from Alcis or Boarmia, or from Acidalia, with which it appears 

 to be associated by Treitschke, the hinder margin of all the wings 

 being indented, especially of the posterior. Duponchel includes it 

 with Boarmia ; but his genus of that name embraces the genera 

 Alcis, Cleora, Boarmia, and others, the div^ersity in the structure of 

 the male antennae of which, exclusively of the discrepancy of the form 

 and colouring of the wings, manifestly exhibits an artificial group.

Pale ochraceous, wings clouded, the anterior with two very delicate and oblique 

 repanded black strigse, one before, the other behind, the middle, with a 

 distinct round fuscous, or black, spot on the disc between; the space behind 

 the posterior striga irregularly clouded with brunneous and lighter shades, 

 with an obscure pale waved striga ; on the costa are also some dark brunmous 

 shades : posterior wings thickly striated transversely with fuscous-brown lines, 

 but less towards the apex than at the base, with a broad deep-brown fascia 

 in the middle, in which is a slender waved black striga ; on the hinder margin 

 of all the wings is an interrupted black line : the head and anterior scales of 

 the thorax and margins of the abdominal segments are brown.
