 nitida, antennis basi et ante apicem sordide flavis aut flavo-albidis ; 

 thorace piceo-fulvo, utrinque profunde foveolato, inter foveas depresso ; 

 elytris regulariter elevato-vittatis, vitta tertia a sutura latiori, interspa- 

 tiis biseriato-punctatis ; nigris aut piceis, purpureo-tinctis, margine 

 exteriori vittaque lata subsuturali flavo-albidis ; pedibus pallide flavis, 

 genubus, tibiis, dorso tarsisque piceis. Long. 2| lin. 



Hah. Fusagasuga ; Muzo ; Western Colombia ( Winhler) ; 

 Magdalena E-iver, Bogota. 



Head longer than broad, elongate-trigonate ; vertex shining, 

 impressed with very fine strigse, visible only under a lens ; front 

 impressed with, a deep fovea ; clypeus sparingly clothed with 

 griseous hairs, its surface on either side rugulose ; jaws pale 

 piceous. Antennae filiform, the second joint short, the third and 

 fourth equal, each twice the length of the second ; four lower joints, 

 together with the eighth and the lower portion of the ninth, 

 obscure flavous or yellowish white. Thorax nearly twice as broad 

 as long ; sides parallel and slightly sinuate from the base to be- 

 yond the middle, thence obliquely converging towards the apex; 

 surface sparingly impressed with very fine punctures ; middle 

 disk deeply foveolate on either side, the space between the fovese 

 depressed. Elytra narrowly oblong, slightly dilated posteriorly ; 

 convex, flattened along the suture ; each elytron with eight 

 narrow costate vittse, the third from the suture broader than any of 

 the others, their interspaces biseriate-punctate ; rufo-piceous or 

 piceous, rarely black, the outer limb aiid a broad subsutural vitta, 

 which covers two or more of the longitudinal costae, yellowish white. 



Nearly allied to D. vittata, separated from that species by only 

 the third costa on each elytron being broader than the rest ; in 

 D. vittata the second and third costae are both broader and of equal 

 width ; in the same species all the costae are rather vsdder and 

 more strongly raised than in the present insect. 



41. DiABROTicA Theimei. Subelongata, postice paullo ampliata, 

 nigra, pedibus flavis ; antennis nigro-piceis aut piceis, basi fulvis, ante 

 apicem flavo-albidis ; thorace flavo-fulvo, disco postico profunde 

 bifoveolato ; elytris regulariter elevato-vittatis, vitta interna latiori, 

 interspatiis biseriato-punctatis ; nigro-piceis aut piceis, margine ex- 

 terno vittaque super costam internam sita, basi et apice coeuntibus, 

 flavis. Long. 2\-3 lin.
