{Lyccena argiolus). — No record is given for this district, but 

 thLs butterfly should be looked for wherever the holly 

 grows plentifully, about the end of May. 



Nocturni. Acherontia atropos. — This species has occurred in 

 many places in this district, and is taken more or less 

 abundantly at Middlesbrough almost every year. I should, 

 however, like records from a3 many Cleveland localities 

 as possible, with dates of appearance and if in larva, pupa, 

 or imago stage. 1 specially want records of the occurrence 

 of the insect in the spring or early summer. 



Sphinx convolvuU has occasionally occurred, specimens having 

 been taken at Saltburn, Kedcar, Yarm, and Middlesbrough. 



Comes to flowers at dusk, especially the flowers of the 

 Tobacco plant. 



SpMnx ligvMri. — Imago taken at Hutton Gate some years 

 since. 



Larva feeds on privet, ash, guelderose, &c. 



Chcerocampa celzrio. — Middlesbrough, single specimen, 1870. 

 (Yorks. list, Porritt, p. 18). 



Sesitdf.e. — With the exception of Crabronijormis {bembeci- 

 formis) none of this family of insects have been recorded 

 for the Cleveland district. As there are eight species in 

 addition to the one already mentioned recorded in the 

 Yorkshire list, I consider that by specially working at the 

 proper season some of these might be turned up in the 

 Cleveland district. The best way would be to work for 

 the larvae in the spring in Ihe various trees aff'ected by 

 these species. 



Onophria quadra. — One recorded taken at Redcar, in 1875. 

 (Yorks. list, Porritt, p. 25). This species occurred all 

 over the country about that period, and there must have 

 been a partial migration. 



Gnophria ruhricoUie. — Guisborough (Stainton's Manual, p. 140). 

 An Ayton gentleman informed me he used to take a black 

 footman fairly commonly in that district, which would 

 probably be this species. 



Imago flies in the sunshine in July over trees, &c. 



Larvae feed on lichens, on larch, &c.
