THE BRITISH NATURALIST. 



[May 



Trichiura Cratsegi. — Larvae common on the moor, Mr. Home 

 has turned up this species in some abundance, the larvae hybernates 

 the first winter, and takes two years to feed up. 



Poecilocampa Populi. — Scarce, Inverurie, Pitcaple and Fyvie. 

 I have recently taken the larvae in some numbers near Pitcaple, the 

 imagines are not so often seen. 



Eriogaster Lanestris. — Not rare at Pitcaple (introduced) the 

 larvae literally swarmed on a hawthorn hedge last year (1890) parents 

 came originally from Essex. 



Bombyx Rubi. — Larvae abundant on waste ground, imagines 

 also common. 



Bombyx Callunse. — Used to be our commonest Bombyx, now 

 rather scarce. A few years ago the larvae were attacked with a kind 

 of dropsical disease, which killed them in hundreds. The Black 

 Headed Gull has also lately paid much attention to the imagines, and 

 in consequence the species has been gradually becoming scarcer. 

 Larva hybernates the first winter, and the pupa the second. 



Odonestis Potatoria. — One taken on Murcal links many years 

 ago (Prof. Trail's Lepidoptera of Dee). 



Endromis Versicolor. — Very scarce at Tarland and near 

 Banchory. 



Saiurnia Carpini. — Common on all moors, emerges in June and 

 July, and often remains two years in pupa. 



GEOMETRY. 



Epione Apiciaria.— Mr. Tait used to take this species about 

 Moneymusk, it has also been taken at Fyvie. 



Rumia Cratsegata. — Abundant everywhere, second brood very 

 scarce. 



Metrocampa Margaritaria. — Common everywhere. 



Ellopia Fasciaria.— Locally common in fir woods. The green 

 variety has been bred occasionally. 



Selenia Illunaria. — Generally common, appears in May and 

 June, nut double brooded. 



Selenia Lunaria. — Rather local, but not rare, a dwarf variety 

 has recently been turned up near Pitcaple.
