PUPAE OF SOME MAINE SPECIES OF NOTODONTOIDEA 47 



the. meson; cremaster (Fig. 4, E) 1.5 mm. in length, the dorsal 

 surface with deep longitudinal furrows and a transverse furrow 

 at the base, a hooked seta laterad at the base of each large curved 

 spine and a transverse row of four hooked setae of the same 

 size at about one-third the length of the cremaster from the 

 distal end. 



Average length 18 mm. ; greatest width 4.5 mm. 



The larvae of this species are slim brown loopers with 

 three rather prominent tubercles and a ridge on the dorsum of 

 the body. They were only taken from sweet fern. When full 

 grown they attach themselves to the leaves with a few threads 

 of silk and usually pull another leaf over it, so that the pupa is 

 entirely concealed. 



SABULODES TRANSVERSATA Drury. 

 The Large Maple Span-worm. Fig. 4, K. 



Color usually yellowish brown, the head, thorax, and ap- 

 pendages of many individuals a much darker brown; the cre- 

 master usually dark brown; surface of body roughened with 

 impressed lines and striations and somewhat tuberculate, there 

 being small distinct, whitish tubercles visible on the appendages 

 and on the eye-pieces ; face-parts with a distinct, high, rounded 

 transverse ridge extending from just cephalad of the middle of 

 each glazed eye-piece; antennae tuberculate, the proximal fifth 

 elevated along the middle line and forming a ridge; setae of 

 thorax and abdomen arising from small, dark brown papillae; 

 abdominal segments with the punctures mostly obscured by the 

 ridges, except on the seventh and eighth segments, the ninth 

 and tenth segments smooth ; abdominal spiracles usually edged 

 with darker brown, those of the second, third and fourth seg- 

 ments touching the wings, the lips of the openings slightly pro- 

 duced and somewhat crescent-shaped; spiracular furrows indi- 

 cated on the fifth segment; dorsal furrow between the ninth 

 and tenth abdominal segments distinct, the caudal margin edged 

 with black and finely toothed; cremaster with four longitudinal 

 ridges and a transverse furrow at base, four of the hooked setae 

 inserted on the dorsal surface, and two on the lateral margin.
