double-brooded, although it states that the larve of the earlier 
species occur in August, whilst that of the later species can be 
found in June and July.

[Of the five insects embraced in the genus Tephrosia, three 
of them—consonaria, Hb., crepuscularia, Hb., and biundularia, 
Bork.—bear such a strong resemblance to each other that 
mistakes in their identification are apt to occur. Typical 
consonaria is readily separated from its near allies; but some of 
the forms of this species occasionally met with are perhaps not 
so easily distinguished therefrom. The two insects known as 
crepuscularia (double-brooded) and biundularia are so closely 
similar that their separation is always a matter of no small 
difficulty to many. Crepuscularia and punctularia, Hb., have a 
co-extensive area of distribution in Europe, consonaria is 
found in all parts of Central Europe, except perhaps Holland 
and Russia; its range also extends eastward to the Amoor. 
Luridata, Bork. (= extersaria, Hb.), is also a Central European 
species, but it does not appear to occur in North Russia or 
North Germany. JBiundularia seems to be confined almost 
entirely to Germany and Great Britain; as a British insect it is 
not peculiar to any particular portion of these islands, but 
occurs pretty generally throughout the kingdom, and is usually 
found in the same localities as crepuscularia.—R. 8.]

By ALFRED THURNALL. 
Durine the past season of 1885 I have taken and bred a good 
many species amongst the Tortrices, and perhaps the following 
list may be acceptable to some of your readers, as an encourage- 
ment for them to work out this group for themselves. 
Tortrix podana, T. xylosteana, T. rosana, T. heparana, T. ribeana, 
T. corylana, T. unifasciana, T. viridana, T. ministrana,—all the foregoing 
common, and generally distributed. . sorbiana, two bred from birch, 
Wanstead. J’. forsterana, six bred from larvee obtained at Whittlesford ; 
spun up in ivy leaves. 
Dichelia grotiana, a few beaten from birch at Wanstead in July.
