leete coccinea; antennis flavis, harum articulis tribus ultimis,

Front impressed with a short longitudinal groove, which runs 
upwards and terminates on a level with the upper margin of the 
eyes in a deep fovea. FElytra impressed on the outer dise below 
the humeral callus with three or four large shallow foveze ; 
in addition on the inner dise are three broad transverse grooves ; 
the first of these, semicircular, bounds the basilar space beneath ; 
the second slightly curved, but the reverse way of the former, 
runs across the inner disc about its middle, and the third, 
oblique, is placed a short distance below the second ; the basilar 
space on each elytron and the surfaces between the transverse 
sulci are slightly raised and thickened. 
2. Diabrotica pulchra. 
Elongata, subparallela, nigra, nitida; abdomine pedibusque flavo- 
fulvis, illo basi tarsisque seepe infuscatis; tarsorum articulis 
duobus ultimis nigris; antennarum articulis basalibus tribus 
obscure fulvis, penultimis tribus albis; thorace transverso, 
disco transversim, excavato, rugoso-punctato, fulvo, piceo- 
infuscato ; elytris subelongatis, dorso subdeplanatis, rugosis, 
elevato-vittatis, viridi-aneis, limbo Jaterali, apice, fascidque
