On the Lepidoptera of St. Helena. 
variable mottled brown, some specimens being much paler 
and more suffused than others. The basal portion is of a 
darkish brown to about a third of the length of the wing, 
followed by a pale almost fascia-like space. The ocellated 
spot near the anal angle (which often forms one of the most 
distinct features in many of the Tortricidse) is only just dis¬ 
cernible, and contains two very small black longitudinal lines; 
adjoining it, near to the inner margin, is a conspicuous small 
dark triangular patch, also containing a black streak. The 
costa itself is variegated with minute white and brown alter¬ 
nate streaks, which are more particularly conspicuous towards 
the apex, the last white line being circular, and thus causing 
the actual apex to appear as a somewhat rounded small brown 
spot. Hind wings pale smoky brown. Thorax concolorous 
with the anterior wings; body of the same hue as the poste¬ 
rior ones. The female is altogether paler, the fore wings 
having the basal portion, except towards the inner margin, 
quite as pale as the fascia. Nevertheless, as I only possess 
two examples (a male and a female), I cannot feel sure that 
these colour-distinctions will prove after all to be perma¬ 
nent. 
The only examples of this obscure little Tortrix which I 
obtained were captured at Cleugh’s Plain; so that it is probably 
a species of intermediate altitudes, though perhaps descending 
rather lower than many which have what I would define as 
an u intermediate ” range. At first sight it has much the 
appearance of many ordinary European forms; and Mr. Bar¬ 
rett informs me that it is closely allied to the common British

Choreutis Bjerkandrella , Tliunb. 
This is a very pretty little species, the dark-brown but 
variegated surface of the anterior wings (which have three 
black blotches exteriorly and two ochreous longitudinal dashes 
at their extreme base, and two somewhat powdered and dif¬ 
fused cinereous transverse fascia?) being elegantly besprinked 
with small metallic spots or fascicles of scales. These scales 
vary greatly in lustre, being more often of a pinkish opal, but 
occasionally (particularly towards the base of the costa) of an 
emerald-green. 
Choreutis Bjerkandrella is decidedly a rather scarce moth 
at St. Helena, and one which appears to be confined to 
intermediate or rather lofty altitudes. I met with it at Plan¬ 
tation and Cleugh’s Plain sparingly, but more frequently at
