Several moths of this species which I took here 

 (Huddersfield) on the 30th of June last year, 1883, 

 deposited eggs, and two batches of them I dropped 

 among grass planted in a large flower-pot. I do not 

 know when they hatched, and, indeed, have no further 

 notes on them til] the 12th of September, when I 

 found that the larvae were about three-eighths of an 

 inch in length, and were living in silken galleries, 

 spun at the bases of the grass-stems above the ground, 

 and in some cases between grass-stems and the sides 

 of their plant-pot. 



Twelve days later, on the 24th, T examined the pot 

 again, to find that the larvas had grown rapidly, had 

 eaten nearly all the growing grass, and were wandering 

 about the sides of the pot and on the gauze covering. 



I then described them as follows : — 



About five-eighths of an inch in length, of average 

 bulk, and of the usual Cramps-shape; the head is 

 slightly narrower than the second segment, it has the 

 lobes rounded, and is, as is also the frontal plate, 

 highly polished ; the body is cylindrical above, slightly 

 flattened ventrally, of nearly uniform width, tapering 

 only a little towards the anal segment; the segmental 

 divisions are well-defined; the tubercles are all 

 polished, large and prominent, the dorsal four oblong- 

 oval in shape, and placed end opposite end, giving the 

 appearance of two transverse ridges on each segment ; 

 the other tubercles are of the usual round form. The 

 tubercles give to the skin a rousfli and uneven 

 appearance, though in reality it is smooth and glossy. 



The ground colour is dingy greyish-olive, of lighter 

 or darker shades in different specimens ; the head is a 

 warm brown, marbled with dark sienna-brown, the 

 mandibles being also dark sienna-brown ; there are 

 no perceptible dorsal, subdorsal, or spiracular lines ; 

 all the tubercles are dark smoky-olive. The ventral
