Lophyrus fabric! i Leach. 



Gregarius on pitch pine (^Piniis rigiJa) at Bellport, Long Island, 

 N. Y. 



Stage before last. — Head blackish brown, shiny ; width 1.5 mm. 

 Body greenish white, a little shining, immaculate except for a faint, 

 double, dusky suranal cloud; segments 6- annulate with minute points 

 on the first, second and fourth. Thoracic feet black ; abdominal ones 

 present on joints 6 to 13. 



Last stage. — Head round, higher than wide, smooth, shining 

 brown-black ; eye blacker ; width 2 mm. Body slightly greenish, 

 white, opaque. A broad, regular, sub-dorsal gray shade line on joints 

 2-13, rarely a narrow fainter dorsal one. A row of square black spots 

 above the stigmatal line resting on the tracheae, broken and partially 

 disconnected by the annulets, one spot on a segment, covering annulets 

 2 and 4 on joints 3-12 ; a large, geminate, sooty black suranal patch. 

 Subventral region white without marks. Thoracic feet black, except at 

 the joints ; abdominal on joints 6-13. Rarely the subdorsal shade is 

 faint. The lateral spots vary somewhat, those on ihe thorax the small- 

 est. Segments 6-annulate, ist, 2d and 4th with a transverse row of 

 minute black points. 



When disturbed the whole brood will elevate the thoracic parts 

 simultaneously. 



Ultimate stage. — Head sordid whitish, shaded with black on the 

 vertex, eye black. Body dull grayish, subventer waxy yellowish, a 

 double dorsal, a broad lateral inky black, smoky band, cut by the in- 

 cisures. Thoracic feet faintly blackish, banded. Anal flap broadly 

 inky. 



Cocoon. — Elliptical, dense but thin, light brown, single. 



Eleven females bred from a single brood of larvae, vary in the num- 

 ber of joints of antennae. Seven have 16 joints, three 17 and one is 

 intermediate, being very indistinctly 17-jointed. The specimens corre- 

 spond with the description of L. pini-rigid(Z Norton, which I consider 

 a synonym oS. fahricii. 



Eriocampa juglandis Fitch. 



Head large, full at the vertex, nearly colorless, shining, a little 

 yellowish, covered with a thick white bloom ; eye black, mouth brown. 

 Body appears dark, greenish or blackish gray, but when denuded of 

 wool it is colorless, though darkly shaded from the contents of the 

 alimentary canal ; coarsely and deeply 6-annulate. The subventral
