LAMPRONIA QUADRIPUNCTELLA, FAB. 147 
tion given by Fabricius, and consequently caused the naming of certain 
varieties as separate species. 
I will first briefly explain the position of the pale spots and then 
notice the more important descriptions of the insect. In fine examples 
the forewings are dark greyish-brown, and in fully marked specimens 
there are five more or less distinct pale spots. For convenience I 
number the spots. 
Spot 1 is vertical and rather elongate, and situated on the dorsum 
before the middle of the wing; more often present in the @?. 
Spot 2, subquadrate or triangular, rises from the dorsum beyond 
the middle. This is the most conspicuous, and present in all specimens 
that I have seen. . 
Spot 8, usually small, just above spot 2, but generally slightly 
nearer the base of the wing, often connected with 2. 
Spot 4, small and triangular, situated on the costa near the apex of 
the wing. 
Spot 5, the smallest, les between spot 3 and the costa; usually 
absent. 
In 1781, Fabricius describes Tinea quadripunctella as follows :— 
_** Alis fuscis punctis duobus albidis. Alae anticae omnino fuscae nitidae, 
punctis duobus in medio approximatis albis, altera ad marginem tenu- 
iorem majori transversa.”’ With two exceptions this diagnosis exactly 
describes that form of the species which exhibits only the second dorsal 
spot and the smaller spot immediately above it, that is the only con- 
Spicuous spots are 2 and 3. The word ‘‘nitidae’’ seems unsuitable, 
but if the wings be viewed without the aid of a lens there is a slight 
sheen visible. In a later description (Hnt. Syst., ili., 2, p. 311) this 
word is omitted. Again, though the spots are not exactly in the centre 
of the wing, the lower one commences and the upper one lies near the 
middle. This form with spots 2 and 8 is then the type of the species. 
Duponchel describes another form in 1844, under the name of Jn- 
curvaria bipunctella, he says his moth has two white spots on the inner 
margin of the forewings, one near the base and the other at the anal 
angle. He then had the form with spots 1 and 2 conspicuous. Spot 
2 is not at the anal angle, but I haye seen the original drawing for the 
figure of this species in Duponchel’s work, and it certainly represents 
this insect and shows the form with two spots on the dorsum, one 
before and the other beyond the middle. 
Zeller, who captured two specimens at Glogau, and had three others 
probably sent to him by Stainton, describes the species in 1852. But 
curiously none of his specimens belonged to either of the forms 
previously described. He calls his moth Lampronia morosa, and states 
that it has a small whitish or yellowish triangle at the anal angle, and 
very obliquely opposite, beyond the commencement of the costal fringe, 
is an indistinct dot of the same colour. Here then we have a descrip- 
tion of that form of the species in which spots 2 and 4 only appear. 
He also mentions a form with no costal spot, which he calls ‘‘ variety b.” 
Here all spots but 2 are absent. 
Haworth, Stephens, and Stainton all recognised the insect described 
_ by Fabricius and employed the name he gave it, but the insect is known 
on the continent by Zeller’s name, morosa. 
The Abbé Joannis, writing in 1915, said that if a specimen of 
morosa should be found having a pale spot on the dorsum near the base,
