and irregularly punctate, the punctures variable in size, open poste- 

 riorly, and from tiie middle of each arises a short recumbent hair, tlie 

 intervals finely and densely granulose: first segment abruptly convex 

 at middle ; last segmerrt rather acutely rounded at apex. Prosternum 

 strongly convex, the surface, coarsely and irregularly punctate, 

 sparsely clothed with a few short semi-erect hairs and the intervals 

 finely and obsoletely granulose; anterior margin with a broadly 

 rounded median lobe, which is feebly arcuatel}' emarginate in front ; 

 prosternal process short, broad, and with a short marginal groove 

 on each side, the sides nearly parallel to the middle of the anterior 

 coxal cavities, where they are emarginate and abruptly narrowed to 

 near the apex, which is very broadly rounded. 



Male. — Not seen. 



Length, 17-25 mm. ; width, 5.5-8 mm. 



This species was originally described by Fabricius from a speci- 

 men from South America in the Hunter collection. Thomson (1878) 

 redescribed the same species under the name resplendens from a 

 questionable locality, probably Surinam or Brazil. Waterhouse 

 (1904) examined the type of this species in the Hunter collection at 

 the University of Glasgow, and also the type of resplendens Thom- 

 son in Oberthiir's collection, and states that eyanipes Fabricius is 

 the same as resplendens Thomson from Jamaica. 



The following material has been examined. Coll. British Mu- 

 seum: One specimen labeled simply "Parry, Saunders 74—18"; and 

 another example from Bath, Jamaica, Avhich was compared with the 

 type by Waterhouse. Coll. Amer. Mus. Nat. Hist.: One specimen 

 labeled "Jamaica," without any additional data. Coll. U. S. Nat. 

 Mus. : One specimen labeled "Jamaica " (donated by the Amer. Mus. 

 Nat. Hist.). 



This beautiful insect is easily separated from all other species of 

 this genus by the elytra not having distinct costae.
