swiftness as to render them invisible until it was stupifled. For opportunities of 

 examining the living female I am indebted to Mr. W. 11. B. Fletcher and Mr. W. C. 

 Boyd. Like that of the last species it is in appearance a mere maggot, with a fat 

 pinkish-white or brownish-pink body, devoid of scales, wings, legs and antennse 

 The head is a mere mask of horny, brown, shining substance, like that usual in 

 larvae, rounded in front, but without regular eye lobes or mouth organs, but having 

 faint indications of rudimentary antennse in the form of short glassy points. The 

 2nd and 3rd segments are protected by, in each case, a large, thin, dark brown, horny 

 plate, which covers the back and extends down the sides ; the 4th segment has a 

 smaller paler plate. Across the lower side of these three segments are slight ridges. 

 The anal segment has a short, bluntly projecting, ovipositor sheath, and beneath it 

 two rounded papilla;. At the sides of the 7th to the 9th segments are small tufts 

 of erect, soft, white hairs. The dried and preserved female is a mere wrinkled 

 shapeless mass. The female in some instances leaves the case on emergence from 

 the pupa, but this is not always the rule. In the Zoologist for 1857 is a curious and 

 interesting account, by Mr. Eichard Weaver, of its habits, and of those of the pupa 

 of both sexes, also of the extremely lively manner in which (as he states) they travel 

 up and down the tubular part of the case to see (?) whether the climate outside is 

 suitable for emergence. 



The larva is pale grey, whitish beneath, with black head, and the three following 

 segments having each a rather narrow, dark grey, horny plate, which almost em- 

 braces the segment ; each has a blackish dividing line down the middle of the back 

 and whitish spots on the sides ; the legs are large and well developed, with black 

 claws. The case is about an inch in length, composed internally of soft, tough silk, 

 and covered with small pieces of dried grass, pointing backward, morsels of bark, 

 seed capsules, and other dried vegetable substances. Food probably grasses, but 

 this is not clearly ascertained. The pupse are as in the previous species, but of 

 course smaller. 



P. MTJSCELLA, Hiib., is a species somewhat similar to P. opacella, of nearly the 

 same size, and even more hairy, but its fore-wings are differently shaped, being 

 narrow for some distance from the base, then broad and rounded, so as to bear a 

 faint resemblance to a battledore. The female and case appear to be unknown. 



It appears possible that this species may be found to occur in mountain districts 

 in this country. There is a specimen in the British series of F. opacella in Dr. 

 Mason's collection, but unfortunately its locality is not known. 



P. GEAMINELLA, S. Y., unicolor, Staudinger's Catalog. — This also is a species 

 which should occur here, since it is one of the commonest and most widely distri- 

 buted of the whole group on the Continent. It is larger and blacker than F. 

 villosella, and has a similar female. Its case is also larger, but sufliciently like that 

 of tlie latter to bo confounded with it. I have a male specimen which was sent me 

 many years ago as a British opacella, I think from the New Forest, but unfortunately 

 the record cannot be found. I therefore merely indicate this as a species to be 



looked for.
