Notes on Coleophora, zvith Descriptions of Two New Species 161 



The second case is cut from the margin of the leaf, and usually 

 bears along its upper edge one of the serrations of the leaf: its 

 length is 3.5 mm. The third case is formed during the latter part 

 of August ; it also is cut from the margin of the leaf, and measures 

 from mouth to apex about 5 mm. The larva hibernates in this case, 

 feeding up in the spring and pupating about the first of June. At 

 this time the case is somewhat flattened, its mouth slightly bent 

 over, the upper edge almost straight with one to three small 

 notches. The lower edge bulges outward in the middle, beyond 

 this it is concave, expanding again at the apex, which is squarely 

 truncate. 



Imagoes in June and the early part of July. 



This species is distinguished from its nearest ally, C. caryaefoli- 

 ella, by the less clearly limited pale streak along the costa ; the dif- 

 ference is well marked when series of the two species are placed 

 side by side. 



There is no doubt that a specimen bred on Prujius americana 

 and compared by Lord Walsingham with C. rufolnteella Cham. 

 (Trans. Ent. Soc. Lond., 430-431, 1882), is a specimen of this 

 species. The description of the case also agrees with that of the 

 present species. 



Types in my collection. 



Four species, namely, C. cratipcnnella Clem. (syn. gigantella 

 Cham.), C. fagicosticella Cham., C. unicolorella Cham., and C. 

 qiiadrilineeUa Cham, were described either from specimens bred 

 from cases found adhering to the bark of trees or from captured 

 specimens, the cases being associated with them by subsequent 

 breeding. No food plant was determined for any of them. These 

 four species have been found to be miners in the seed capsules of 

 Juiiais tennis Willd., which is very common in beaten paths across 

 lawns and fields, and of Juucus effusus L., a swamp rush. In 

 two instances the larva utilizes some portion of the inflorescence 

 in constructing its case. Larvae of the four sDecies are often 

 found feeding together on a single clump of the food plant.
