female of this species, and there seems to me no doubt whatever that 

 it is only the female type. Humphreys and Westwood in their 

 British Moths " also figure and describe an additional species to 

 this genus in the name of renigera, based on the fact that specimens 

 of the insect existed in some of the old cabinets, and were supposed 

 to have been taken near London. The species however has since been 

 placed, I believe by Mr. Kirby, with the AgvotidcB, and is of very rare 

 occurrence in Europe, and is certainly not British. 



With the short space at my command, I have been unable to 

 satisfactorily work out the geographical distribution of C. Hawortlin. 

 In the South it seems to be extremely local and confined to the 

 counties of Sussex, Hants, Norfolk, Huntingdon, Bedford, Cambridge, 

 Northampton ; in Staffordshire, Derbyshire, Cheshire, Yorkshire, 

 Lancashire, Durham, Cumberland, and Westmorland, it is taken com- 

 monly though rather local ; there is also a record of its occurrence in the 

 Isle of Wight. I only hold two Welsh records — -Denbighshire and 

 Glamorganshire — but it is no doubt taken pretty generally throughout 

 Wales. In Scotland it seems to be abundant and generally distributed 

 in the Highlands, and is to be also occasionally met with in the 

 Isle of Arran. In Ireland it has been taken commonly in the East 

 and West Counties, and the variety Hibernica is to be taken on the 

 Dublin and Wicklow hills. Dr. Staudinger says that it occurs in 

 Germany, North France, Livonia, Finland, Lapland and the Ural 

 mountains. 



In conclusion, I desire to record my many thanks to Messrs. 

 South, Porritt, Fenn, Reid, and Farren for their help in working out 

 the geographical distribution of this insect; and to Mr. Tutt for his 

 kind assistance in naming the varieties.

Notes. 



Forcing Agrotis Ashworthii. — Having been successful this 

 autumn in rearing Agrotis Ashworthii from the egg, and as this larva 

 has the reputation of being very difficult to rear, perhaps a few notes 

 as to the way in which I managed them may be interesting and useful 

 to others who may in future have a similar opportunity of breeding 

 this rare and beautiful moth.
