indicated black-brown stripes on each side, a very small spot 

 of the same colour between the two upper lines, and a third 

 line, rather irregular, above the stigmata. These stripes are 

 interrupted by the intersection of the segments. Hairs on 

 the body short and very delicate. Head blackish, shining^ 

 as also are the legs. In a case covered with smooth bits of 

 dried grass, of a paler colour than those generally used 

 by the allied species, and placed lengthwise in a more regular 

 manner. In shape cylindrical and of pretty uniform thickness. 

 Some of the bits of grass extend a little beyond the true case. 

 The larva feeds on grasses and is not rare in fields, chiefly 

 in hilly districts, but is not easy to find, as it keeps close to 

 the ground among the herbage. (Bruand.) Cases found 

 in this country agree most accurately with the foregoing 

 description. M. Bruand goes on to say : " I have found, 

 during many years, a number of cases of this species in a 

 damp meadow. These are of a much larger size than those 

 found on the mountains. The larvae in these large cases 

 pupate at least eight days after the others have emerged, 

 and produce moths of a larger size, I think that this difference 

 in size is caused by the damp locality. The larger I call the 

 type, the other I have figured as var. 'pulliparvella. M. 

 Lederer tells me that he finds these two sizes also at Vienna, 

 but also considers them forms of the same species." 



June to April, on grasses. Apparently feeding, at times^ 

 more than one year. Mr. C. A. Briggs found a full-sized 

 case upon grass in July. The larva attached its case firmly 

 to a box for about ten days, then woke up and fed on for the 

 rest of the summer. 



Pupa of a brown colour — that of the female resembling that 

 of a Dipteron. In the larva-case, spun up on the stems of 

 grasses or neighbouring plants, or, in rare instances, on a 

 neighbouring post or other convenient object. In the pupa 

 state about a fortnight. 



The male moth flies in the daytime and, I think, only in the
