Pupae of Some Maine Species of Notodontoidea 61 



Length 25 to 27 mm. ; greatest width S mm. 



The larvae of this species feed on certain species of Vac- 

 cinium, the common bhieberries and deerberry, also on An- 

 dromeda. As its name implies it is the largest species of the 

 genus. The method of pupation is probably the same as for 

 the other species of Datana, but it has not been observed by 

 the writer. 



DATANA INTEGERRIMA Grote and Robinson. 



Fig. 5, G. 



Color dark brown ; crest not very prominent, the longitud- 

 inal furrows not deep or well defined ; face-parts and appendages 

 very rough with impressed lines and other surface sculpturing; 

 antennae never meeting on the meson nor extending as far cau- 

 dad as the mesothoracic legs ; maxillae about one-half the length 

 of the wings and slightly longer than the prothoracic legs ; meso- 

 thoracic legs meeting on the meson caudad of the maxillae ; 



median line of the prothorax and metathorax slightly elevated; 

 thorax noticeably punctate among the transverse striations ; ab- 

 dominal segments rather finely punctate, with few other mark- 

 ings ; furrow between the ninth and tenth segments edged with 

 black, the caudal margin elevated and almost evenly toothed; 

 both ninth and tenth abdominal segments punctate ; each half 

 of the cremaster with three short, almost equal projections. 



Length 17 to 19 mm. ; greatest width 6 mm. 



The larvae of, this species feed on walnut, hickory and oak. 

 They are found in large companies and always keep together 

 while feeding. They pupate in the ground.

Fig. 5, H. 



Color bright reddish brown, .sometimes yellowish brown ; 

 crest on front seldom showing longitudinal furrows ; face-parts 

 and appendages rugose with indeterminate transverse striations, 

 the appendages less rugose than the face-parts ; maxillae three- 

 fifths the length of the wings or a trifle shorter, always longer 

 than the prothoracic legs ; cephalic margin of prothorax slightly
