darker, front and mid tibiae with dark marks near the middle and 

 before the tip. Forewing mostly brown, with many small pale spots, 

 mostly on or near costal area before stigma, along veins, and an 

 oblique area across the apical cells, a white spot on margin in each 

 apical cell; behind toward base are two larger pale areas, sometimes 

 connected, both somewhat triangular, mostly behind the anal vein, 

 but the outer one reaching forward to the cubitus ; there is much black 

 hair along cubitus and anal veins. Hindwings faintly gray, marked 

 with brown toward tip, especially in front. 



Venation much as in other species, fork one plainly before fork 

 two in forewing, not in hindwing; outer margin of wing hardly 

 convex. Male genitalia similar to R. maculipennis Ulmer; but the 

 intermediate appendages are much shorter, the superior median 

 process more heavy, the inferior appendages broader, not widened 

 before tip, and the penis shows two teeth below. 



Fore wings, 20 mm. long; 6 mm. wide (Ulmer gives no size to 

 B. maculipennis), other specimens 15 to 22 mm.

The male genitalia are very similar to those of R. maculipennis 

 Uhner from Kuku-nor, but the lower appendages are evidently 

 heavier in H. hageni, the superior median piece broader at base ; and 

 in the description of forewings there is no mention of the large pale 

 spots in anal area, and the ground color is evidently pale, while in 

 hageni the membrane is largely dark except for pale spots.

 Plate 30, Figure 64 



Head dark, hair mostly black; palpi dark, basal joint of antennae 

 dark, beyond pale brown, tips of joints narrowly pale; thorax above 

 dull reddish brown, sides hardly darker, bristles from strips and 

 those above wing base black. Abdomen dull reddish brown, tip and 

 venter paler. Legs pale, front and mid tibiae mostly dark, but a 

 narrow pale band a little before the tip. 



Forewings brown, densely and rather evenly sprinkled with pale 

 spots, the brown with short golden hair, the pale spots with white 

 hair; much black hair near cubitus and anal veins. The pale spots 

 most numerous along veins, many in costal area, one on margin 

 in each apical cell, no larger pale areas. Hindwings gray, slightly 

 marked with brown in apical area in front, and along outer margin 

 are a few faint pale spots.
