 (partim). 



Face not projecting, smooth, or slightly hairy. T(mgue well- 

 developed. Palpi moderately long, porrect or somewhat ascend- 

 ing, rough-scaled or hairy beneath; terminal joint short, obtuse. 

 Antennae in $ bipectinate, towards apex simple. Thorax not 

 crested, hairy beneath. Femora glabrous; posterior tibiae in $ 

 sometimes strongly dilated, with internal groove and tuft of hairs 

 from base. Forewings of ^ with well-developed fovea; 10 and 

 1 1 long-stalked or coincident, their common stalk often connected 

 with 12, 10 sometimes connected with 9, or rarely 11 apparently 

 from 12, not connected with 10. Hind wings normal. 



Type, B. roboraria Schiff., from Europe. 



The occasional connection of veins 9 and 10 presents no dif- 

 ficulty, but the relations of veins 10, 11, and 12 demand special 

 attention. Veins 11 and 10 may be stalked, as in Fig. 4; or 

 completely coincident, as in Fig. 5. In the first instance, 1 1 may

be connected with 12 by a short anastomosis, as in Fig. 6; or by 

 a bar, often of considerable length, as in Fi^. 7, every gradation 

 between these two being observable. This bar unites 12 with 

 the common stalk of 11 and 10 shortly before, or at tlieir bifur- 

 cation; 11 is never connected with 12 after their sepai-ation
