Family Chrysopeleiidae 



This family includes the genus Chrysopeleia which was formerly 

 included with the Elachistidae. It has the same arrangement of parts 

 as that in the genus Elachista but retains the fronto-clypeal suture and 

 has no cremaster (Fig. 95). Until more is known of the relationships 

 of this genus it seems better to place it in a family by itself. The ap- 

 pendages are slightly elevated and firmly soldered to each other and to 

 the body. They extend well on to the seventh abdominal segment, so 

 that there appears to be no motion possible between any of the body 

 segments. There is no cremaster present and only a few short straight 

 setae at the caudal end of the body. The abdominal spiracles are pro- 

 duced and tubular. The pupae are very small, being only about 3 mm. 

 in length. 



The following species was examined : 

 Chrysopeleia ostryacclla Chambers. 



Family Oecophoridae 



This family (Figs. 97 and 98) includes those pupae in which the 

 fronto-clypeal suture is not present for its entire length and which 

 have large maxillary palpi, usually reaching the proximo-lateral angles 

 of the maxillae. All the species examined showed the presence of very 

 fine setae arranged in groups over the surface of the abdomen, but 

 these were hard to locate in Psilocorsis. The incisions between the 

 segments are very deep in all members of the family. Of the three 

 genera studied Psilocorsis, Agonopteryx, and Depressaria, the first 

 seemed more nearly related to the Stenomidae, while the other two 

 were typical gelechiids, except that the fronto-clypeal suture was never 

 distinct. It seems probable that a revision of the group might sepa- 

 rate these genera. The table to genera will indicate the principal dif- 

 ferences. The body is usually strongly depressed and 5-10 mm. in 

 length. The following table will serve to separate the genera:
