 Long. 8 millim. ; terebra 55 millim. 



Hab. Panama, Volcan de Chiriqui 2500 to 4000 feet, Bugaba (Champion). 



Antennae nearly as long as the body, densely pilose; the third and fourth joints 

 subeqiml ; the basal joint produced at the apex on the underside. Head shining, 

 retreating somewhat sharply behind the eyes ; the top impunctate, the face coarsely 

 and rugosely reticulated and with three stout keels running down the centre ; eyes 

 margined on the underside ; clypeus rugosely punctured ; front moderately depressed 

 in the centre, the central furrow wide ; the clypeus, the oral region, the mandibles 

 (except at the apex), and palpi reddish. Thorax shining, impunctate; scutellum 

 triangular, flattish ; metapleural suture deep, moderately wide. Petiole with the central 

 part wide, broadly raised in the middle, the bordering furrow narrow, the sides sloping 

 away from this gradually. Abdomen not much longer than the head and thorax 

 united, and narrowing from the second segment ; second segment considerably shorter 

 than the third, its apex transverse ; the apical ventral segment is large and ploughshare- 

 shaped; the apical segments at their junction, and the sides, narrowly, are whitish. 

 Legs stout, pilose. Wings longish ; the cubital nervure with a round curve ; the 

 recurrent nervure received shortly before the transverse cubital one ; the second cubital 

 cellule is, on the lower side, a little longer than the third.

 Long. 7*5 millim.; terebra 3-5 millim. 



Hab. Nicakagua, Chontales (Janson); Panama, Bugaba (Champion). 



Closely related to B. erythrostoma, but with the rufous colour on the head more 

 developed, the occiput being almost entirely of that colour ; the palpi are light rufous. 

 The antennae are scarcely so stout ; the anterior legs are entirely rufous, as is also the 

 mesothorax ; the petiole is more sharply vertical, and has the inner furrow wider ; the 

 abdominal segments are not so broadly lined with white, and the ovipositor is shorter.

Very much resembling in form, sculpture, and coloration what I have regarded as 

 the male of B. nicaraguensis ; in coloration differing from that insect in having the
