adequate to produce the extensive extinction or migration of 

 species I am supposing. 



Amidst the hills there are, however, lakes, ravines, and 

 richly-wooded glens, where the naturalist will find ample 

 occupation, and, of the latter, Powerscourt claims special 

 notice : its vicinity to Dublin has caused it to be more 

 frequently visited than other places, and thus enhanced its 

 entomological reputation ; but the Deer Park is truly a col- 

 lector's Paradise. It is a secluded valley, of about two 

 miles in length, between the Sugarloaf and Douce mountains, 

 and is terminated by perpendicular cliffs, over which the 

 Dargle river leaps with a clear fall of upwards of a hundred 

 feet. Shaded by its grand old oaks and most ancient 

 hollies, 



" There through the summer day 

 Cool streams are laving, 

 There while the tempests sway 

 Scarce are boughs waving." 



Scott. 



The late Mr. Tardy,, of Dublin, one of the earliest and 

 most zealous students of Irish Entomology, was so attracted 

 to this neighbourhood that he used to pitch a tent in the 

 Valley, and camp out for weeks in the summer. Amongst 

 his notable discoveries was that of Mesites Tardii in the 

 hollies of Powerscourt : it is still to be found there, although 

 sparingly compared with Killarney. 



The following species of Lepidoptera (besides hosts of 

 commoner things) have been taken at Powerscourt, mostly in
