TREPILENA FIMBRIA. 
BROAD-BORDERED YELLOW UNDERWING. 
Plate LIV. Figure 1. 
Localities for this species, formerl} r thoughtso extremely 
rare (my friend, Mr. Dale, of Glanville Wootton, had, 
for several years, with a few other specimens, the wing of 
one in his cabinet which he had found in a spider’s web), 
but which is now taken plentifully, are York, Langwith, 
Stockton Forest, Sandal Beat, and Melton Wood near 
Doncaster, Bolton Abbey, Sutton-on-Derwent, Brighton, 
Faversham, Canterbury, Lytham, Swinhope, Ticehurst, 
Arundel, Horndean, Carlisle, Lewisham, Milstead near 
Sittingbourne, Ilfracombe, Sherwood Forest, Ivillarney, 
West Wickham, Bristol, Bowdon, Black Park, Dorking, 
Birkenhead, Edinburgh, Darlington, Burton-on-Trent, 
Exeter, Halton, Lewes, Huddersfield, Lyndhurst, Pem- 
bury, Plymouth, Manchester, Scarborough, Stowmarket, 
Tenterden, Shrewsbury, Worthing, Worcester. 
The perfect insect appears in June and July. 
The caterpillar is brown with a paler line along the 
back, and a row of slanting whitish stripes, alternating 
with some white spots in the place of the usual line on 
either side of the back. 
The date of the appearance of the caterpillar is in 
March and April. 
It feeds on the primrose and other low plants. 
The chrysalis is found beneath the surface.
