 the mandibles broad and concave, outer surface rather densely clothed with 

 short yellowish pubescence ; palpi pale luteous ; antennae longer than the head 

 and thorax, fulvo-testaceous, and when viewed sideways they have a scolloped 

 appearance, the joints beneath being contracted at their sutures; thorax broad 

 and truncate in front, prothorax closely punctured, depressed above and some- 

 what prominent on each side ; mesothorax subconvex, with large, deep, sparse 

 punctures ; on each side over the tegulie a deeply impres.sed longitudinal line ;

 base of the wing and continued beneath the first submarginal to near its base, 

 receiving the first recurrent nervure beyond the middle ; third submarginal very 

 short, narrow, transversely quadrate, receiving the second recurrent nervure at 

 the apex ; legs fulvo-testaceous, clothed with pale yellowish pubescence, quite 

 dense on the tibise and tarsi ; abdomen elongate, sparsely punctured, shining, 

 the punctures becoming finer and less distinct towards the apex, the pubescence 

 on the basal segments short and thin, longer and thicker on the apical segment ; 

 first segment large and much swollen, with a short peduncle, the segment nearly
