 Long. 9 millim. ; terebra 6 millim. 



Hab. Panama, Bugaba 800 to 1500 feet {Champion). 



Antennee rather stout, microscopically pilose ; the scape but slightly produced at the 

 apex beneath. Head cubital, broader than long, retreating behind ; front depressed, 

 broadly, but not very deeply, a furrow leading down from the ocelli in the centre. 

 Face irregularly and rugosely reticulated ; a sharp keel running down from the outer 

 side of each antenna, and another keel parallel to the eyes, the space enclosed by these 

 two keels being transversely reticulated ; clypeus finely punctured, projecting. Palpi 

 long, sparsely pilose. Thorax stout ; the middle lobe of the mesonotum scarcely raised 

 or separated from the lateral ; the furrows almost obsolete. Metathorax short, broad, 

 gradually sloping to the apex. Abdomen not much longer than the thorax, broad at 

 the base, gradually narrowing from the second segment to the blunt apex. The raised 

 central part of the petiole is depressed at the base and becomes slightly narrowed 

 towards the apex; the lateral part is broader than the central, and has a shallow, 

 shining, furrow down its centre. The suturiform articulation is broad, curved back- 

 wards in the middle, and shallow. Legs stout, the tibiae and tarsi densely pilose, 

 opaque; femora shining. The wings are lighter towards the apex; the recurrent 

 nervure is received in front of the first transverse cubital one; the second cubital 

 cellule is a little shorter than the third ; at the base the cubitus forms a round curve. 



A broad, stout insect with large wings, and readily known from the following two 

 species by the red abdomen and shorter ovipositor.
