GEOMETRlDiE. EUPITHECIA. 279 



second more distinct white one, somewhat angulated and sinuated on its 

 outer edge, the space from these fuscescent, and having a sinuated white 

 striga parallel with the hinder margin, on which is an interrupted black line, 

 edged without with whitish : posterior wings dusky-white, with a central dot 

 and a more or less distinct whitish fascia behind the middle ; and the male 

 with a fuscous lobe at the base. 



Slightly variable as to the depth of colour and the intensity of markings. 



Caterpillar whitish-green, with white dorsal stripes : it feeds on the sallow 

 (Salix caprea) : — the imago appears in June and August. 



Not common : it lias been taken at Coombe-wood, up Robin- 

 Hood-lane, and in the New Forest. 



Genus CCXXVI. — Eupithecia, Curtis. 



Palpi rather long, projecting obliquely beyond the forehead in form of a beak, 

 densely covered with scales, those at the base waved and elongated ; triarti- 

 culate, the basal joint long, slightly robust, and a little curved, the second 

 shorter, attenuated to the apex, terminal minute, subglobose : maxillae mode- 

 rate. AntenncE simple in both sexes, pubescent within in the males : head 

 small } forehead prominent : eyes globose : thorax slender : wings entire, 

 extended horizontally during repose, the hinder margins rounded ; anterior 

 elongate-lanceolate ; posterior small, oblong-ovate : abdo?nen short, slender, 

 obtuse in the males, stouter and acute in the females. Larva elongate, slender, 

 naked, with pale lateral lines. 



The insects of the present genus may be readily known by the 

 smallness and brevity of the posterior wings, compared to the bulk 

 of the anterior ones, as well as from the circumstance of their 

 reposing with them perfectly horizontal with their ciliated edges in 

 close contact with the substance on which they rest ; — the anterior 

 wings are very long, and have their hinder margin rounded : — the 

 structure of the palpi may also be mentioned as a distinguishing 

 character.

Anterior wings reddish-white, with a fuscous patch at the base, then a some- 

 what distinct rufous fascia, followed in the middle by a broad, nearly solid, 

 incurved, ashy-brown one, in which is an elongate black spot ; behind this is 

 a second rufescent fascia, the margin of the wing being cinereous, with a faint, 

 waved, white striga, and three distinct fuscescent clouds ; on the hinder margin
