c. Lobes indicating the presence of pilifers always present except 

 in Gallerinae (Fig. 69) and Oeneinae. (Fig. 80). 



d. Maxillary palpi usually present, if absent, then abdominal 

 segment seven is movable in the male, the body covered with 

 a spiny armature, and both prothoracic and mesothoracic legs 

 extending cephalad between the eye-pieces and the antennae, 

 the former reaching nearly to the cephalic margin of the 

 glazed eye, or a deep furrow lined with setae present on the 

 dorsum between the ninth and tenth abdominal segments ; 

 antennae never clubbed at the distal end; femora of the pro- 

 thoracic legs usually visible ; labial palpi very seldom visible 

 except as a small triangular or polygonal area caudad of 



the labrum and between the pilifers. „„„ . T __ „ TT ^_, . 



PYRALIDOIDEA. 



dd. Maxillary palpi never present; antennae always clubbed at 

 the distal end ; femora of the prothoracic legs never visible ; 

 a deep furrow lined with setae never present on the dorsum 

 between the ninth and tenth abdominal segments; labial 

 palpi never visible except as small triangular or polygonal 

 areas caudad of the labrum between the pilifers and often 

 entirely concealed. PAPILIONOIDEA. 



cc. Lobes indicating the presence of pilifers never present. 



d. Mesothoracic wings on the ventral surface at meson usually 

 extending considerably beyond the caudal margin of the 

 fourth abdominal segment, if not, then the body depressed, 

 mostly in the thoracic region, the incisions between the mov- 

 able segments very deep on the dorsum and venter and less 

 deep at the lateral margins, and the caudal part of the an- 

 tennae always adjacent on the meson for a considerable dis- 

 tance ; abdominal segments 1-4 usually longer than the other 

 segments ; epicranial suture always present. 



e. Maxillary and labial palpi present and well developed and 

 a large portion of the prothoracic femora always exposed ; 

 if maxillary palpi are not present then the fronto-clypeal 

 suture never visible; prothorax distinctly shorter on the 

 meson than at each side, so that each half is triangular in 

 outline; appendages soldered to each other but not to the 

 body wall; fronto-clypeal suture never visible; antennae 

 with the caudal portion very rarelv touching and not 

 moniliform in appearance. YPONOMEUTOIDEA. 



ee. Maxillary palpi usually present, but labial palpi and pro- 

 thoracic femora seldom visible, if visible, then the fronto- 

 clypeal suture distinct ; prothorax usually the same length
