174 LE CONTE.— LONGICORN COLEOPTERA 



The antennse of the European iEdilis are described by Mulsant as not ciliated ; 

 the thorax spinose, with the disc unequal ; the ovipositor of the female is a long 

 corneous tube, protected above by a long acute extension of the superior last joint of 

 the abdomen ; the inferior joint is also produced and is emarginate at the extremity. 

 In a male of A. nodosus the analogue of this is seen in a short truncate anal plate 

 projecting beyond the emarginate extremity of the abdomen. 



1. ^. NODOSUS, fuscus, dense griseo-pubescens, thorace lineis duabus, elytris apice rotundatis vitta tenui 



interrupta, macula oblonga antics bifida pone medium, lateribusque ante medium nigerrimis, antennis 



pedibusque nigro-annulatis. Long. -60 — 1*0.

Middle and Southern States ; rare. The male has a knot at the extremity of the 

 fourth joint of the antennse ; Halderaan has restricted the genus Astynomus 4-Dej. to 

 this species, v^^hich he had no right to do, the genus being characterized by Laporte 

 in the Suites a BuflFon (ed. Dumesnil. 2, 463), and being precisely equivalent to 

 jEdilis Serville ; moreover the slight sexual enlargement of the fourth joint of the 

 antennse seems rather too slight a difference to entitle this to rank as a distinct genus. 



2. M. OBSOLETDS, griseo-pubescens, supra parce grosse punctato, thorace maculis magnis fuscis variegato, 



elytris apice subacuminatis, basi fasciisque undulatis obliquis tribus fuscis, antennis pedibusque fusco- 

 annulatis. Long. -52.

GRAPHISURUS Kirby. 



Antenna corpore longiores, minime ciliatse, articulo 1™° elongate, subclavato. 



Mesosternum latiusculum apice truncatum. 



Abdomen articulo ultimo superiore et inferiore maris emarginato, feminas valde elongate. 



Femora clavata tarsi posteriores articulo 1^"° elongato. 



The female has a long exserted ovipositor, as in ^dilis ; the thorax is not at all 

 inequal ; the lateral spine is acute and placed behind the middle. The males can be 

 distinguished from Liopus only by the emarginate terminal superior abdominal 

 segment : the apex of the elytra is transversely truncate.
