Family Tineidae 



In this family the free abdominal segments are 3-7 in the male; 

 no females were available for examination. Segments 1-3 separate dor- 

 salty at dehiscence. The appendages are very slightly soldered to- 

 gether and all separate readily except the metathoracic legs and an- 

 tennae, which extend beyond the caudal margin of the wings and are 

 quite firmly fastened together, the legs being underneath the antennae. 



The appendages are also slightly soldered to the body as far as the 

 third abdominal segment. The arrangement of parts is shown in 

 Figures 30 and 31. The fronto-clypeal suture is indicated by a clear 

 line in the otherwise fairly well-chitinized cuticle. Segments 3-8 of 

 the abdomen bear a cephalic row of spines on the dorsum directed 

 caudad, while the ninth segment bears an interrupted group of spines 

 directed cephalad. There are none of the fine spines of the generalized 

 type of pupa present in this family. The tenth abdominal segment 

 shows a prominent lateral projection on each side, ending in a spine. 

 The setae of the body are very conspicuous. The pupae are about 4 

 mm. in length.

Family Heliodinidae 



This family has usually been associated with the Yponomeutidae, 

 but it seems from pupal characters to be more closely related to the 

 tortricids. It is very similiar to these in arrangement of parts; the 

 Heliodinidae, however, have longer maxillae and they plainly show 

 that dorsal motion is possible between the second and third abdominal 

 segments. There are also curved setae at the caudal end of the body 

 in the genus Brenthia (Figs. 32 and 33) strongly resembling those 

 found in the Epiblemidae. Choreutis (Figs. 34 and 35) has a small 

 dorsal plate on the tenth segment with a strong seta at each end which 

 appears to represent an early state in the development of a cremaster. 

 The possession of a single row of dorsal spines on the abdominal seg- 

 ments, however, is like the remainder of the Tineoidea, and it is easier 

 to classify them as such. They differ from the remainder of the super- 

 family in having one more free segment in the male, abdominal seg- 

 ments 3-7 being free in the male and 3-6 in the female. The thorax
