122 PORRITT: NEUROPTERA AND TRICHOPTERA OF YORKSHI : 
_ Asynarchus ccenosus. Entirely a northern species. Ab 
on the high moorlands in the south West Riding, 
Marsden, near Huddersfield, and Dunford Bridge. I have 
taken it on Thorne Moor. 
Stenophylax alpestris. Another great rarity in Britain, an 
own county locality—the wood at Dunford Bridge—is no 
only precise spot where it is known to occur. The 
specimens taken there were by Mr. John Harrison, of Bat 
in 1891, since which time it has also been taken by myself and 
Mr. William Mansbridge, as well as again by Mr. Harrison. 
Stenophylax infumatus. Mr. G. C. Dennis took a fine spe 
of this northern species when collecting with me at 
Howard on the 13th of June last (1896). 
geet ry rotundipennis. <A _ rare species everyWi 
Mr. R. McLachlan took it at Scarborough in the seco 
“of August 1866; and I captured a fine example at 
Howard on the evening of September 8th last (1896). 
ss ge ede stellatus. Common. Huddersfield ; 
rd; Pickering ; Grassington. 
pen latipennis. I have specimens labelled 
field, Dunford Bridge, Saltburn, etc., but am a little do 
about some of them. ‘The species is very closely 
S. stellatus, and the females I am quite unable to separate. 
inclined to think .S. sfe//afus is the commoner insect 
eastern division, and .S. datipennis probably so in the 
western division. 
Stenophylax concentricus. Seems to occur everyW 
not abundantly anywhere. Huddersfield ; Doncaster; 
York ; Beverley ; Malham ; Hayburn Wyke. 
Stenophylax vibex. In 1896 Mr. B. Morley gave me’ 
specimens he had taken during the year at Skelmanthorp 
Huddersfield, where it is evidently not uncommon, but 
never seen it elsewhere in the district. Mr. ! 
records it from Thorne Moor and from Scarborough. 
Micropterna sequax. Apparently common through 
county, Huddersfield; York; Saltburn ; Beverley ( 
Hewett) ; Castle Hawerd; 5; ete. 
Micropterna lateralis. Common on the Meltham Moots 
Huddersfield, and exceptionally dark in colour. © 
taken it at Castle Howard.
