306 CRAMBUS SELASELLUS. 



grasses cut from a chalk hill, which proved unsuitable 

 for them, and they all made their escape. (William 

 Buckler, October, 1877; Note Book III, 215.) 



While larva-hunting along the coast last year, 1878, 

 on the 17th of May, I found one of a Cr ambus I did 

 not then know, and brought it home to rear, to figure 

 and describe. 



It was in a green frass-covered tube or gallery, 

 partly attached to a stone lying on a damp place, 

 among small mixed growths of Poa maritima, Spar- 

 Una striata, and Hordeum maritimum ; at the beginning 

 of June I came upon another like it, though this was 

 close to a stone amongst a short growth of Poa mari- 

 tima solely. 



These two larvae soon fed up and converted the end 

 of each gallery into a cocoon, and the moths emerged 

 on the 13th and 22nd of July ; they were kindly 

 named for me by my friend Mr. 0. Gr. Barrett, who 

 affirmed that C. selasellus was known to haunt rank 

 and coarse grasses in other situations far inland ; I 

 can, therefore, only regard the two larvae thus found 

 under somewhat exceptional conditions to have been 

 the offspring of stragglers from a neighbouring marsh. 

 The full-fed larva is seven-eighths of an inch in 

 length, and stout in proportion, tapering very little 

 near the anal extremity ; the head is black and glossy, 

 and a glossy blackish-brown plate dorsally divided 

 with a pale line is on the second segment ; the large 

 shining spots of dark warm brown are darkest on the 

 back, lighter brown and smaller on the sides and belly, 

 each spot having a fine dark hair; the shape and ar- 

 rangement of the spots are quite as usual with many 

 of the genus ; the anal plate is lightish brown ; the 

 rest of the skin of the body is of a warm brown colour, 

 melting gradually into rather lighter, olivaceous, or 

 ochreous-brown on the sides, the belly, and the hinder 

 segments, smooth but dull, yet showing distinctly 

 through it a faintly darker dorsal vessel and the pale 

 tracheal thread besides other portions of the interior;
