a series of parallel folds and at the same time somewhat crumpling 

 the upper surface. About the same time it eats out holes in the upper 

 parenchyma around the edges of the mine which show through as a 

 series of pale spots. In the last stage the process is continued and 

 the leaf is frequently folded double. Pupation takes place in a cocoon, 

 elhptical in outline, about 6 mm. long by 4 mm. wide. The cocoon 

 is composed of a single layer of silk and is attached closely to the upper 

 lining of the mine and loosely to the lower. 



The pupa (Fig. 20, 5) is 3.5 mm. in length, at first pale yellowish 

 but becoming darker with age. The head ends in a pyramidal point 

 directed downward, without visible serrations. The head, wing, leg 

 and antennal cases are dark brown. The dorsal surface of abdominal 

 segments 2 to 7 is armed on the front half with dark brown spinules 

 and on the posterior quarter with a band of much smaller ones. The 

 first and eighth segments show traces of a similar armature. Seg- 

 ments 4 to 7 are movable. When about to transform the pupa works 

 its way partly out of the mine. In one instance we found a pupa skin 

 projecting half its length through the upper surface of the leaf. 



The moth (Fig. 20, 6) has an expanse of 6 to 7 mm. The fore wings 

 are reddish brown with golden reflections in certain lights. Each is 

 crossed by four narrow black bands bordered on the outside with white. 

 The third and fourth bands are connected by a black bar. There is a 

 black dot and a white crescent at the apex. The head is tufted with 

 reddish brown hairs. The antennae are long and slender and are 

 banded with black and white. The hind wings, abdomen and legs 

 are dark gray, with the tarsi black and white. 



In 1873 Frey and Boll (Stett. Ent. Zeit. 34:215) record rearing 

 moths from mines in the leaves of Lonicera sempervirens from Cam- 

 bridge, Mass., which they with doubt referred to Lithocolletes trifas- 

 ciella Haworth. In 1878 (Ibid 39:270) they described L. fragilella 

 from specimens from Texas reared froni mines on the underside of 

 the leaves of Lonicera albida. In 1891 Lord Walsingham (Ins. Life 

 3:326) stated that he had examined one of the specimens bred by 

 Frey and Boll from Lonicera sempervirens from Cambridge and referred 

 hy them with doubt to L. trifasciella and pronounced it to belong to 

 their L. fragilella. Cook (Third Kept. Mich. Agr. Exp. Sta. for 1890: 

 117) records rearing what appears to be this species from honeysuckle 

 irom Gratton, Mich., although he identified it as L. trifasciella Stainton 

 ;and his description of the mine, larva and pupa does not agree with 

 ihat of L. fragilella.
