 This species is not' very common, and only one appears to 

 have been met with in ^Northumberland. *' A pupa got under 

 moss at Sallows near Allerdean Mill, turned out this Moth on 

 ]2th June, 1887." (G. Bolam, Trans. Ber. F. C, vol. xv., p. 

 304). In Durham it is reported from '' Gibside, not common," 

 by Mr. T. H. Hedworth; ''not common at Greatham and !N"or- 

 ton," by Mr. Gardner. I took a single specimen at Hartlepool 

 in 1875, and have oocasionally found it on tree trunks on the 

 road side between Hartlepool and Stockton-on-Tees, the last 

 being in 1893.

 I have met with but two notes of the occurrence of this species 

 — one in Ornsby's Durham ; the other in the MSS. of the late 

 "Wm. Backhouse, who says he took it on tree trunks at Sunny- 

 side. I admit it with some hesitation, for neither in Ornsby's 

 Durham nor in Mr. Backhouse's notes do I find any record of 

 the next species, which, while generally common, is almost un- 

 distinguishable from Tridens except in the larval stage. Tridens^ 

 however, has been taken in various parts of Yorkshire, aud there 

 is nothing improbable in its occurrence with us. I, therefore, 

 include it, with these remarks, and with the idea that if these
