the same colour, an oblong-conic spot towards the middle, and 

 an oval or ovate one above it duller; beyond the middle is an 

 ear- shaped or rhomboidal spot resting on a trifid character, 

 both ochreous, these are relieved by a dark brown or black, 

 with a line of spots of the same colour between the nervures 

 near the posterior margin ; inferior wings and abdomen black- 

 ish or fuscous, sometimes palest at the base, with a dark spot 

 in the centre, the apex of the abdomen in the males ochreous, 

 with a fuscous line along the middle in the upper wings. 



This moth is a northern species, and occasionally the cater- 

 pillars commit sad ravages in pasture lands by devouring the 

 roots of grass, as related by Linnaeus, who states that they 

 will not touch the Alopecunis j)J'citensis nor the Trifolium pra- 

 tense (pi. 181). Mr. Wailes has lately made some interesting 

 remarks upon its habits, in the 2nd Part of the Entomological 

 Magazine. I well remember when Mr. Dale and myself 

 visited Keswick in 1827, that the grass on a large portion 

 on one side of Skiddaw appeared dead, and I found numbers 

 of the larvae of C. Graminis crawling about. I used to find 

 the moths flying close to the ground towards sunset in the 

 neighbourhood of Norwich, also in meadows near Covehithe 

 Suffolk, and in the flowers of the Ragwort at Inverary and 

 Kinnordy, Scotland. Mr. Dale has sent me the following 

 localities; July Aroquhar and Loch Long; Aug. near Car- 

 lisle canal, Ambleside and Skiddaw; near Manchester; 

 Whittlesea Mere : Comb-wood ; Devon ; and Knowle Hill 

 Dorset. 



Rooks and pigs are very fond of the caterpillars and very 

 useful in the destruction of them.

Dull yellowish brown ; superior wings with an elongated 

 pale ochreous spot at the base above the central nervure, and 

 another subelliptical one more towards the middle, with a 

 lemon-shaped one above it, beyond the middle is a trapezoid 

 spot resting on a trifid character, all of the same pale colour, 

 some of them being partially relieved by a dark brown ; be- 

 tween the nervures at the posterior margin are obscure, elon- 

 gate-trigonate brown marks : abdomen and inferior wings 

 fuscous; cilia pale ochreous. 



I am fully aware that the C. Graminis is a most variable 

 species, but as I have never seen one similar to the specimen 

 figured I consider it may be a distinct species. It was cap- 

 tured last September in the county of Mayo, Ireland, by Henry 

 Walker, Esq. 



The Plant is Pedicularis sylvatica (Common Lousewort).
