Male. Testaceous. Head and the appendages, pectus, abdomen and 

 legs black. Head with the sockets of the antennae and the two intermediate 

 spots testaceous; an abbreviated Inteous band and a luieous d<>t on each 

 side near the mouth. Eyes as remote from each other as those of B.gigantea, 

 Prothorax elliptical, with a large scutcheon-shaped black spot, which 

 extends to the hind border and includes a distinct lyre-shaped mark; fore 

 border slightly vaulted, not extending heyond the head; sides rounded, 

 slightly sinuated along the humeri ; hind border viMy slightly rounded, its 

 middle part black. Mesothorax with two black dots on each side. Meta- 

 ihorax- with an interrupted and irregular black band. Abdomen with an 

 irregular black band on each segment; these bands are more determinate 

 on the under side, where there are also three irregular black stripes. Cerci 

 black, with lawny tips. Legs rather short and stout ; trochanters testaceous ; 

 femora with an apical testaceous dot; tarsi testaceous beneath. Fore wings 

 rather narrow; a black stripe extending from the base along the Innneral 

 vein to nearly one-third of the length ; veins brown for a short space from 

 the tip of the stripe; anal furrow black. Hind wings pale cinereous: veins 

 brown on the anal or posterior area, except towards the base, where they 

 are testaceous like those of the discoidal area and of the costal area. 

 Length of the body 21 lines; of the wings 45 Hues. 



The brown veins in the hind wings of this species distinguish it from 

 B- giganlea, and from B. qiiadrifera, and its less dilated prothorax from 

 B. Mexicana. The eyes are less remote from each other than those of 

 B. Cubensis and of B. Brasiliaua, and the hind wings are ciiiereous. It 

 resembles B. minor in structure, but differs in the colour of the wings. 

 It differs from B. Sulzerii in the rounded sides of the prothorax, which is 

 less dilated than that of B. trapezoidea and of B.ferruginea. It has some 

 resemblance to B. fraterna, the fore wings of the latter are mostly brown.
