I am inclined to believe that tbe “alar, expanse” given by 
Gruenee (27 mm) for this species is erroneous, as the % speci¬ 
men I have before me in perfect condition, and which con¬ 
forms in all ^essential particulars to Gruenee’s description, is 
smaller than L. oplitlialmica Grn.,to which the same expanse 
is given. In his note to this species, M. Gruenee remarks on 
its small size, which would corroborate this opinion,

This species is the most recognizable of the genus by its 
whitish thorax and humeral spot. Appears to be of rare oc¬ 
currence, 
latebricola nov. sp. 
Anterior wings straight along the costa; exterior margin 
not so oblique as in the two preceding species. All the lines 
very indistinct. Thorax and humeral spot dark grey. ’ Base 
clouded with blackish without any visible defining line. Me¬ 
dian space greyish, lightest near the basal shade and showing 
the discal spot, as in all the species of this genus, rounded, 
light, small, with a black centre. Terminal space darker than 
median, with a black shade near the apex on the costa, and 
the transverse posterior line faintly visible, sinuate. Poste¬ 
rior wings greyish with discal lunule and a marginal darker 
line. Under surface of wings greyish without definite mark¬ 
ings; a discal lunule and the traces of two very indistinct 
bands on the inferior wings. Abdomen greyish, blackish on 
the two first rings; lighter underneath.

Besembles L. dormitans (which it exceeds in size) in the 
markings and coloring, but differs by the straight costal, and 
less oblique exterior, margin, in which respect it approaches 
L. Donbledayi^ but differs greatly from Guenee’s description 
of that species.
