fact that a very large maxillary palpus is present in all genera, and that 

 spines which reach well around to the ventral surface are found on 

 abdominal segments 2-10, especially on the tenth segment. There 

 are no setae yet developed on the anal rise, and there is not as much 

 consolidation of the fixed caudal abdominal segments. The seventh 

 segment in the female seems but recently to have lost power of motion. 

 The abdominal segments are more nearly equal in length than in the 

 Tortricoidea. 



Family Aegeriidae 



The pupae of this family vary considerably in size, from the genus 

 Aegeria, with species varying from 8—16 mm. in length, to the genera 

 Memythrus and Bembecia, containing the largest species examined, 

 varying from 20-25 mm. They are all provided with various forms 

 of cutting plates for working their way to the surface, most of these 

 being on the head, which is heavily chitinized at the cephalic end and 

 usually has many ridges and projections, making it difficult to deter- 

 mine the sutures. The clypeus often bears a sharp transverse ridge, 

 sometimes toothed, which undoubtedly serves the same purpose. The 

 body is elongate, cylindrical, with the abdominal segments approxi- 

 mately equal in length, showing a generalized condition. The arrange- 

 ment of parts in a pupa of this family is shown in Figures 36 and 37. 

 It will be noted that the maxillary palpi are very large, and they remain 

 uniformly so throughout the family. The appendages extend beyond 

 the wings in most of the genera, but the caudal parts of these are not 

 soldered to the body wall. The fronto-clypeal suture is always dis- 

 tinct along the lateral margins of the front from the proximal ends of 

 the antennae almost to. the invaginations for the anterior arms of the 

 tentorium, but only shows transversely as a paler band of color in the 

 strongly chitinized cuticle as indicated by the dotted line in Figure 36. 

 Dehiscence invariably follows the course of this suture, and the front 

 with the antennae are separated from the rest of the head parts. The 

 epicranial suture is often obscured by the numerous elevations of the 

 vertex and front, but it is always present. The antennae are always 

 enlarged at the proximal end and again at the distal end, where they 

 are somewhat club-shaped, thus differing again from the Tortricoidea. 

 The mandibles are distinctly elevated in most genera. The wings are 

 narrow and pointed, differing markedly from those of the Tortri- 

 coidea. They are not soldered to the body wall at their distal end. 

 The thorax always has a carinate median ridge, which may be distinct 

 on all the segments, and is always distinct on the prothorax and the 

 cephalic half of the mesothorax. The alar furrows are very deep, and 

 one edge, usually the mesal one, is sharp and heavily chitinized. There 

 are always two rows of spines on the dorsum of some of the abdom-
