large, ovate; no distinct angulated extradiscal line, E. abmnthiata.

Fore wings pointed, with numerous transverse, fine, wavy, black lines, angulated 

 sharply out waul: extradiscal line forming a large right angle opposite the

 spots and marginal lines /■;. miserulata. 



Fore wings still more pointed than in E. miserulata, lineated transversely ; beyond 

 the diseal spot, the wing dull carneo-cinereous, with the extradiscal line in 

 the middle; a huge rectangle opposite the diseal dot; palpi long E. lutcata. 



Form and size of /:'. miserulata, but russet-brown ; extradiscal brown line curved 



opposite the diseal dot , E. strattonata. 



B. Of large size: whitish; diseal dot very linear; wings very long: 



White, with brown bands and patches ; COSta reddish-brown, interrupted by clear

A. Of rather small size : 



Like E. miserulata, but with a decided russet tinge, more distinct lines, the extra- 

 discal less acutely bent, and five lines on hind wings E. rotundopunctata. 



Like E. rotundopunctata, but nearly twice as large, and with still longer palpi ; 



with similar markings, but smaller linear d Bcal dots E. longipalpata. 



Like B. absynthiata, but much larger, with the wings much produced, and outer 

 edge sinuous E. behrensata. 



B. Of large size, with very long wings : 



Like E. ravocostaliata, but more cinereous, with a russet-brown costo-apieal patch. E. nevadala.

EUPITHECIA ALBICAPITATA, 71. Sp. Plate 8, fig. 1. 



2 <3 , 1 9. — A rather small species, with large acute palpi; a scutellate area 

 of hairs on the vertex, quite distinct from the similar scutel-shaped front, 

 which rounds to a point more than usual. Palpi very long and large, longer 

 than the head, acute, porrect, dark on the sides, paler above and at the lips. 

 Antennae slender, simple, very minutely ciliated beneath. Prothorax doubly
