176 Butterfield: Lepidoptera tn the Wilsden District. 
spite of this flower failing, I observed a few. In October insects 
came freely to sugar. Orthosta macilenta was extremely 
abundant; other common ones were Mzselza oxyacanthe (mostly 
var. capucina), Agriopis aprilina, Calocampa exoleta, Agrotis 
suffusa, a few Scopelosoma satellitia, also two C. vetusta. 1 
believe only one example of the latter species has heretofore 
been recorded in the Bradford district. 
Melanic forms do not appear to have been particularly con- 
spicuous. It is noteworthy that dark specimens of Scoparia 
cembrae and S. ambigual’s were observed, and I secured several 
nearly black specimens of the ubiquitous Woctua xanthographa. 
Mr. Porritt, in his interesting paper on ‘ Melanism in Yorkshire 
Lepidoptera,’ read before Section D. at the British Association 
at York (1906), does not include in the list therein given the 
two latter species. It is singular that the only specimen of 
Amphidasys betularia, captured by my father, Mr. E. P. Butter- 
field, was a normal type. I secured a few black Boarmzia 
repandata from Blackhills. Among the black forms captured 
were a few Cidaria immanata and Miana strigilis. My father 
and I caught at sugar one night two striking dark forms of 
Agriopis aprilina. The most interesting capture of the year 
was a rather dark example of Agvotis agathina in perfect 
condition. It was caught whilst it was circling around a lamp 
at the base of Harden Moor. 
Among moths which are associated with the moor, or rather 
moor edges, Acidalia fumata, A. tnornata, Eupithecia nanata, 
and 2. minutata were fairly common, as were also the Tortrices 
Penthina sauciana, and Amphysa gerningana, and the pretty 
Tinee Lxapate congelatella. On Harden Moor I caught three 
Cloantha solidagints. Whilst searching with a lamp for this 
species, I noticed an abundance of the larve of Hadena pist. 
Scodiona belgiaria appears to have been rather scarce, for I only 
saw two males. 
Among the Geometers caught in September were several 
Oporabia autumnaria. This has not previously been recorded 
for the district. Mr. Porritt, in his ‘Yorkshire Lepidoptera,’ 
does not give it specific rank, though it is included as a species 
in ‘The Entomologist Synonymic Reference List.’ 
Butterflies, as usual, have been conspicuous by their absence 
—that is to say, in the immediate neighbourhood of Bradford— 
with the exception of Cabbage Whites; a Small Tortoise Shell, 
caught on December 4th, is the only record I have!
