the dise fuscous, finely rugose; scutellum obscure fulvous; elytra 

 opaque, closely and finely rugose, the latéral margin flavous, this 

 colour gradually narrowed tow.irds the apex, the latter with a 

 round tîavous spot, not emarginate ; legs fuscous, the base and 

 apex of the femora and the base of the tibiae flavous. A single 

 spécimen, evidently closely allied to *S. annulicornis Clark, but 

 difiering in the entirely black lower joints of the antennae and their 

 two apical flavous joints, also in having the latéral flavous margin 

 of the elytra narrowed posteriorly and with an extra apical 

 flavous spot. 



Diabrotica Gahani n. sp. 



Below more or less fulvous, above pale green, antennae 

 fulvous, the apical joints paler; thorax impunctate, shining, 

 without dépressions ; elytra finely rugose-punctate, green, the 

 suture at the base rufous. 



Length 3 lines. 



Head impunctate, green, the labrum and palpi fulvous, antennae 

 extending to more than half the length of the elytra, fulvous, the 

 ninth, tenth and the base of the terminal joint flavous, the basai 

 joint green, the third twice as long as the second, the fourth joint 

 as long as the preceding two together; thorax subquadrate, the 

 surface smooth, shining and impunctate; scutellum fulvous; elytra 

 slightly widened posteriorly with a short longitudinal sulcation 

 below the shoulders, the surface closely rugosely-punctate, opaque, 

 green, the suture at the base rufous, this colour in shape of a 

 short triangular spot; breast, tibiae and tarsi fulvous, abdomen 

 flavous, femora green. 



Allied to D. subsulcata Baly and several other species, but 

 differing in the colour of the suture at the base of the elvtra, the 

 green colour of the latter is however subject to variation and 

 sometimes becomes flavous after death. 



Luperodes bolivianus n. sp. 



Flavous, the head, the breast and the poslerior tibiae and tarsi 

 black, thorax impunctate ; elytra closely pnnetured, the anterior 

 half and a transverse band below the middle, metallic blue. 



Length 3 Unes. 



Head impunctate, black, shining, the lower four joints of the 

 antennae fulvous, the following three joints black, the rest wanting, 

 the third joint shorter than the fourth ; thorax subquadrate, one 

 half broader than long, the sides nearly straight, the posterior
