2. H. rectangula Ottolengui. Outer boundary of sub-basal patch starting per- 

 pendicularly down from Cu, and then right-angled; inner boundary also more 

 perpendicular. Ground darker brownish gray; pale patches above antemedial 

 patch, and at middle of costa, more decidedly pinkish.

2. PSEUDOTHYATIRA Grote 



Accessory cell closed by a short crossvein r, running from R 3 to stem of R, +5 , as 

 in Habrosyne. Similar to Efabrosyne, but with the fore wing relatively longer, 

 with a stronger tooth and tuft at anal angle, and costa more arched. Caterpillar 

 similar, but with the brown dorsum shading gradually into the paler venter. 



1. P. cymatophoroides Guenee. Ash gray, somewhat mottled and shaded with 

 pink in antemedial region and over end of cell; base typically blackish; transverse 

 anterior line of a group of three waved blackish lines; transverse posterior of a 

 similar series of waved lines, more sinuous, and blackish only at costa; with a 

 blackish patch beyond it on inner margin, preceded by a white line; a dark patch 

 on costa before apex, crossed by a white lunule; subterminal line of small, wedge- 

 shaped marks between the veins. Orbicular circular; reniform oblong, both small; 

 with raised central dark dots and gray rings; fringe pinkish. Hind wing pale 

 brownish gray. 42 mm. (H 40:25.) 



Variety expultrix Grote is similar, but lacks the blackish shades, the antemedial 

 group of lines being light gray, and the hind wing rather darker gray. (H 40:26.) 



June to August. Caterpillar often with one or a series of lateral white spots, 

 especially in the type form; on oak and thimbleberry.

3. EUTHTATIRA Smith 

 (Thyatira, in part) 



Fore wing rather long and narrow, with arched costa, without a scale tuft at 

 anal angle; hind wing longer on costa; accessory cell formed by the anastomosis 

 of Rj, and R 4 (fig. 433); a well-marked tuft on fold before transverse anterior line, 

 but no tufts on orbicular and reniform spots. 



The caterpillar lives concealed in a loosely folded leaf; it is translucent, with 

 four black spots on the head. 



1. E. pudens Guenee. Gray, with large pinK spots, the basal one large and oblong, 

 with the tuft in its outer end; a large one on middle and one at apex of costa, and 

 a smaller and browner one at anal angle. Orbicular horizontally elongate, small, 

 touching reniform, both pink -filled; the other markings obscure. 45 mm. (H 40:23.)
