longitudinal impressed line. Legs unarmed, the anterior femora 

 waved at the base ; all the femora faintly annulate with alternate 

 broad bands of testaceous and dusky brown, commencing at the base 

 with testaceous. Joints of abdomen marked only by the incisures, 

 the last three joints, and especially the ante-penultimate, considerably 

 swollen; the posterior angles of the last joint produced posteriorly 

 into two short, rounded lobes, delicately serrated along the inner and 

 posterior edges, the serrations directed inward. Styles moderately 

 slender, cylindrical, a little upcurved and a little incurved, the tip 

 depressed and a little twisted, so that the straightly docked apical 

 edge is oblique, its angles rounded off. 



Length of body, 79 mm. ; of hind tibiae, 34 mm. ; of middle tibiae, 

 24 mm. ; of fore tibiae, 38 mm. 1 d , Eastern slope of the Peruvian 

 Andes. 



This species is evidently allied to B. tvrgida Westw.

Blackish, very slender. Head blackish, with smooth parts ; except- 

 ing apical joints of palpi, and a narrow ferruginous stripe behind the 

 eyes, pale ferruginous ; the stripe continued over the whole length of 

 pro- and mesothorax, accompanied by a similar rather broader stripe 

 connecting the fore and middle coxae. Pro- and mesothorax with a 

 slightly impressed medio-dorsal line, and very slight and very blunt 

 tuberculations above ; metathorax and basal joints of abdomen pale 

 above and below. Tegmina scarcely longer than the thorax, the ner- 

 vures elevated and on the apical half blackish, in contrast to the pale 

 base and interspaces. Folded portion of the wings with a similar effect, 

 the part covered by the tegmina being pale, the rest blackish, with 

 very pale or whitish lines, a median very slender, and one on either 

 side broader but still very slender; rest of wing blackish fuliginous, 

 with a large basal, rounded, very broadly obovate, whitish spot, reach- 

 ing nearly to the inner border, and in the middle of the wing half 

 way to the outer border. Legs blackish brown, the femora paler at 

 the base and lineate with ferruginous. Styles short, moderately 

 slender, cylindrical, a little upcurved, bluntly rounded and a little 

 thickened at the extremity. 



Length of body, 31.5 mm.; of antennae, 31 mm. ; of wings, 21.5 

 mm. ; of fore tibiae, 7.5 mm.; of middle tibiae, 5.75 mm.; of hind 

 tibiae, 9 mm. 1 ?, Peruvian Maranon. 



Apparently allied to P. ambiguum Westw.
