Larva. The mandibles bidenticulate, with distinct smaller 

 teeth within, the surface with three setae [pl.27, flg.l] ; the eyes 

 present, five in number [pl.27, fig.5] ; the basal segment of the 

 leg with four or five setae and the surface densely papillate 

 , [pl.27, fig.4] ; the labrum emarginate in front with four long 

 marginal setae, the outer the longer, with four discal setae, 

 the distal pair not much more than one half the length of the 

 proximal pair, with two long lateral setae, and four sensory 

 pits [pl.27, flg.2] ; the anterior tergal setae of the mesothorax 

 and the metathorax divided into three well marked groups, those 

 of the first five abdominal segments straight and not divided, 

 those of the fourth and fifth abdominal segments broader art 

 middle than at the sides, those of the sixth and seventh ab- 

 dominal segments straight and consisting of from four to eight 

 setae, most of which are larger than thof^e of the ordinary type; 

 the posterior tergal setae of the mesothorax and metathorax 

 and first five abdominal segments straight and of about the 

 same length as the anterior tergal setae, those of the sixth and 

 seventh abdominal segments similar in outline but consisting 

 mainly of setae twice the length of those of the ordinary type, 

 the seventh abdominal segment with about four extra setae on 

 the front margin near the middle; the supraspiracular setae of 

 the first five abdominal segments small and coalesced with the 

 anterior tergal setae, those of the sixth abdominal segment dis- 

 tinctly separated from the anterior tergal setae, those of the 

 seventh abdominal segment wanting; the infraspiracular setae 

 of (the first seven abdominal segments all of aboiut the same 

 size, small and oblique; the anterior sternal setae of the pro- 

 thorax wanting, the posterior sternal setae indistinct and di- 

 vided longitudinally into tAvo groups, the anterior and posterior 

 sternal setae of the mesothorax and metathorax indistinct and 

 not joined, the posterior sternal setae of these segments divided 

 longitudinally, the sternal setae of the abdomen in small groups 

 and not divided; the pedal setae of the abdomen well marked 

 on the anterior segments and becoming smaller on the posterior 

 segments; the caudal margin of the seventh abdominal tergite 

 produced into a blunt projection and constituting the apex of 

 the abdomen [pl.30, fig.3]. 



Pupa. White; the legs, wing pads, and the antennae not 

 closely attached to the body; the second and third segments of
