Forty-ninth Report on the State Museum 



Description of Moth and Larva. 

 The moth is about three-fourths of an inch in spread of wings, of a 

 reddish-brown or purphsh color. Its front wings are marked with two 



yellow spots on their front margin, 

 the outer one of which is the 

 larger, and with two faint yellow 

 lines extending from these to the 

 inner margin ; the hind wings 

 are crossed by two wavy yellowish 

 lines. The fringes of both pairs 

 are long, with a silken luster and 

 are golden-yellow in color : this 

 last feature has given the moth in 

 Europe the pretty popular name

form, it may be serviceable to quote its description as given by Mr. Walsh, 

 who was the first to describe it: 



Length half an inch ; diameter, 0.07 inch, tapering slightly at each end ; 

 color a dirty greenish-brown; beneath, yellowish brown; the first and last 

 segment above, shining, smooth and yellowish-brown with a few irregular 

 whitish hairs ; segments 2-1 1 each, with a transverse row of about six 

 long whitish hairs, each hair proceeding from a lighter colored tubercle 

 with a dark central spot. Head rufous. Legs and prolegs normal, viz., 

 six legs, eight abdominal prolegs and two anal prolegs. Wriggles much 

 and runs backward like a Tortrix; suspends itself by a thread, and spins 

 a whitish web while still in the larva state and before the time arrives for 

 passing into the pupa state. 



Correspondents of Mr. Walsh give as additional characteristics of the 

 " worms '' that they are " ridged," and have " the extremities a little 

 darker than the center." 



Its European History. 



From its not being recorded as an injurious species by European 

 writers, although known for over a hundred years, it is doubtless another 

 instance of introduced insects becoming pestiferous with us which were 

 not harmful in their native home. It is not treated of by Westwood, 

 Curtis, Whitehead, or other European economic entomologists, so far as 

 I know. Miss Ormerod, in her Seventeenth Report, in an extended 

 notice oi Pyralis glaucinalis Linn., the "Hay-stack Moth," which is the
