slightly angulated below costa. Contiguous to this lino, on the disc, 

 is a smaller, subquadrate, velvety-brown patch (concolorous with the 

 collar) between the transverse anterior line and the orbicular spot, 

 which latter is large, concolorous with the rest of the wing, with par- 

 allel sides and narrowly annulated with pale scales tending to become 

 obliterate above and below. Between the orbicular and renitbrm spots 

 is a second and larger subquadrate velvety-brown patch on the cell ; 

 the reniform spot is also concolorous with the rest of the wing, full 

 sized, of the normal shape, and faintly and narrowly annulated with 

 pale scales. The transverse posterior line is distinct, even, and is regu- 

 larly subarcuate. Beyond it, a dark wide transverse shade obtains 

 between the transverse posterior line and the subterminal, the latter 

 merely indicated by the irregular outer edge of the shade being brought 

 into relief by the paler color of the terminal space. External margin 

 narrowiy edged by a dark linear shade. Posterior wings ample, of the 

 usual blackish cinereous hue, silky. The external margin is depressed 

 below the costal angles. The color slightly deepens towards external 

 margin, which is narrowly edged with a darker linear shade. Beneath, 

 the primaries are blackish, without markings; on costa is seen the in- 

 ception of a transverse line at apical third, brought into relief by pale 

 costal scales. Secondaries darker than on upper surface ; a discal dot 

 (apparent also, but more faintly above) and a transverse, darker, but 

 indistinct line; the costa and the region at costal angle are covered 

 with blackish scales.

The present and next following species are slender in form, but 

 agree with the characters of the genus as now understood by Continen- 

 tal Entomologists. 



Agrotis geniculata, n. sp. (Plate 7, fig. 54,*^ .) 



%. Size moderate; form slender. Blackish-brown, silky. Labial 

 palpi blackish, fringed beneath and tipped with grey scales. The 

 general' caputal squamation presents a speckled appearance owing to 

 the mixture of blackish-brown and grey scales. On the vertex the 

 scales are somewhat massed. Antennae dark, wirh two rows of minute 

 serratures. Collar mixed blackish-brown, a little darker than thorax ; 

 a distinct blackish line crosses the prothoracic pieces posteriorly, form- 

 ing two curves. Thorax and tegulae mostly brownish-grey ; at the 

 sides the tegulae are shaded with dark brownish. Legs brownish, 

 dotted wuth pale grey ; hind tibia strongly spurred. Under thoracic
