Emydia cribrum. — Tho "spockled footmiiu" was given to me 

 in a list for the Great Ayton district as l)eing pretty 

 common, but I am afraid this must be a mistake for some 

 other species. The larvae feed on heath, hut I do not 

 know of its having occurred anywhere in the North. It 

 is certainly not mentioned in the Yorkshire list. 



Cossus /i(fniperda. — Great Ayton, rare (W.II.). I am under 

 the impression that I have seen one or two larvae that 

 have been taken in the Middlesbrough district during 

 past years. 



The larvae feed in the trunks of large trees of ash, 

 willow, elm, &c., feeding on the wood seldom 5 feet from 

 the ground. 



Trichiura cratmji. — Between Ayton and Stokcsley (T. Mel- 

 drum). Larvae feed on hawthorn, elm, sallow, &c., in 

 May, and are often to be found on dense and closely 

 cropped hawthorn hedges bordering roads. 



Dicranura hicuspis. — Guisborough, several (W. Jeffrey, Ent. 

 W. Int., Sep 11, 1858). Middlcslu-ough (Zool, 1857, xv., 

 5825). Yarm, empty cocoons (W. Lister, li^ntom., 1869, 

 iv., 231) ; between Ayton and Htokes](;y (T. Meldrum). 



This insect should certainly be turned up again in this 

 district (it is taken, I believe, every year in the Bear- 

 borough district), .seeing that its main food plant, alder, is 

 one of the commonest trees in Cleveland, occurring every- 

 where. 



Imago appears in May— June. 



Larva3 on alder, July — September, 



Pupae, October — April, spun up on alder trunks, rarely 

 above 2 ft. from the ground Resemljle a Brazil nut. 



NOCtUSB. Acronyda alni. — Guisborough (W. Jeffrey, Ent. "W, 

 Int. iv. 188). This species occurs frequently in the 

 Scarborough district, and I think it is only a question of 

 searching well for it to be turned up again in Cleveland. 



The larvffi feed on a number of trees including alder, 

 willow, oak, sallow, birch, &c.
