abundance of flowering plants. On August 17th and 21st Cyaniris 
argiolus was seen at Worcester Park. On the 29th half a dozen 
Acidalia dimidiata hatched from pup, the eggs of which were found 
on July 25th on lettuce. A run was made over to Wicken again on 
August 80th for two days. At this late period of the year there is neces- 
sarily not much to be done, but those who want Hyboma strigosa will, 1£ 
their patience lasts, beat out, perhaps, one larva from hawthorn after six 
hour’s work. Bailey had taken something like half a dozen, but I was 
unrewarded. Wicken is probably the limit of its range as one is there 
off the chalk, to which formation the species is attached. A few larvee of 
Hecatera chrysozona were still about on the lettuce seeds, and Manduca 
atropos was being found fairly commonly in potato fields. Something 
like three dozen larvee and pupze had already been secured by different 
individuals. It is quite probable that this species breeds in and around 
Wicken yearly, as besides potato there is a large quantity of Lyciuwm 
barbareum grown in the cottage gardens, and should a few larve feed up 
and pupate at the roots of this, the large conspicuous chrysalis would 
escape the inevitable detection to which it is exposed when ensconsed 
at the roots of potato. Upon my return home a large number of 
Acidalia dinidiata had emerged, in fact all the pupa-cases were empty, 
which goes to show that the second brood was not a partial, but a 
complete one. 
On the getieric name Micropterix (Micropteryx), Hub. 
By J. W. TUTT, F.E.S. 
Although the proper use of the name Micropteryx was fully cleared 
up in The Natural History of the British Lepidoptera, vol. 1., pp. 
129-180, it is still so generally misapplied by some lepidopterists that 
a brief summary of the principal facts may be advisable. Hubner, in 
the Verzeichniss, p. 426 (1826), founded the genus Micropterix for the 
three species mucidella, Hb., podevinella, Hb. (=aruncella, Scop.), and 
pusilella, Wb. (=calthella, Linn.). The first species is an Hlachistid, 
and leaves aruncella and calthella as representatives of Micropteria, 
Hb. 
In 1889, Curtis separated the British Micropterygid and Hriocraniid 
species from Lampronia under the name of Hriocephala, and cited ‘‘ cal- 
thella’”’ as the type. This made Mriocephala synonymous with Micropteria, 
Hb., for Stephensin 1835 had constituted calthella the type of Micropteryx. 
Stainton, however, maintained (Trans. Ent. Soc. Lond., 1850, pp. 20 
et seq.) the name Hriocephala for the ‘‘calthella”’ group, but, in 1851, 
Zeller (Linn. Hnt., v., pp. 822-8) reverted to the original use of the 
name Micropterya and kept it for the ‘calthella’’ group, creating 
Eriocrania for the ‘‘ purpurella”’ group. ‘This division was main- 
tained by Snellen (De Vlind. van Nederland, pp. 1065 et seq.) in 1882. 
Karby properly sinks (Lloyd’s Nat. Hist. Lep., v., p. 815) Hriocephala, 
Curt., as a synonym of Micropterix, but states that the type of the 
latter genus is aureatella, a species not included in Hiubner’s genus. 
This is undoubtedly incorrect as calthella had been fixed as the type by 
Stephens. It is quite evident that Meyrick’s use of the name 
Eriocephala for the calthella group, and Micropteryx for the purpurella 
group, is equally erroneous. Chapman, in his important papers on 
this group in the Trans. Ent. Soc. London, 1898 et seq., commenced by
