PUPAE OF SOME MAINE SPECIES OF NOTODONTOIDEA 61 



their openings elliptical; abdomen finely punctate; cremaster a 

 straight spine with the distal end widened and bearing two or 

 three recurving hooks on each side, each hook bearing minute 

 setae on its mesal margin which are very easily destroyed. 



MELALOPHA INCLUSA Hubner. 

 Fig. 5, C and I. 



Color usually yellowish brown, with darker brown on the 

 thorax, the cephalic margin of the abdominal spiracles, the ce- 

 phalic margin of the movable abdominal segments and the cre- 

 master; antennae smooth, ending opposite the prothoracic legs; 

 maxillae one-third the length of the wings or slightly less ; first 

 three segments of the abdomen usually more elevated than the 

 thorax and forming a distinct curve ; abdominal segments finely 

 punctate, the cephalic margin of each movable segment much 

 more densely punctate, the ninth and tenth segments almost 

 smooth ; first abdominal segment with the scar of the larval 

 tubercles apparent, in some specimens as a dark spot on each 

 side of the meson, in others a small, but distinct tubercle in the 

 same position; cremaster (Fig. 5, I) 1 mm. in length, with either 

 two or three recurving hooks on each side. 



Length 13 to 16 mm. ; greatest width 5 mm. 



The larvae of this species feed on poplar. Several of the 

 larvae live together in a sort of tent formed by drawing two or 

 three leaves together with threads of silk. They spin a loose co- 

 coon, placing it among the leaves in captivity, but no cocoons 

 were found during the summer's collecting. 



Genus APATELODES Packard. 



Cephalic half of body to the caudal margin of the wings 

 wider and thicker than the caudal half, which tapers gradually 

 to the short blunt cremaster ; body surface highly polished, none 

 of the face-parts or appendages prominently elevated so that the 

 surface is smooth and even ; epicranial suture present, but faint ; 

 vertex about twice as long at lateral margin as at meson ; fronto- 

 clypeal suture sometimes indicated by an impressed line ; ceph- 

 alic margin of labrum about twice the width of the caudal 

 margin ; labial palpi represented by a small pentagonal area just
