Between 7 and 8 mm. in length, elongate oblong oval, somewhat 

 shiny although alutaceous, the elytra densely and shallowly punctate 

 with faint lateral costae; pale yellow, the head with a spot on the

 tubercles a little swollen, a small median depression above them and 

 a narrow carina running down the lower front, occiput smoothly 

 rounded, sometimes with a few pimctm-es, pale yellow with a small 

 brown spot in the middle at base and when the head is protruded a 

 smaller spot visible on each side; mouthparts edged with brown. 

 Antennae pale with the basal and apical joints a shade lighter, tip 

 of terminal joint black. Prothorax about a thkd wider than long 

 with sides shghtly rounded and with a transverse depression, finely 

 punctate. Scutellum brown. Elytra faintly alutaceous, shining, with 

 fine, dense and semistriate punctation, pale, each elytron with elongate 

 brown spots, one on the humerus, a second along the side not con- 

 nected with the humeral spot, and a third at apical curve, in the middle 

 of each elytron one below the scutellum, a second before the middle, 

 and a thkd after the middle. Body beneath and legs entirely pale, 

 the breast a shade deeper in coloring, middle and hind tibiae with a 

 spine. Length 6.7-8 mm.; width 2.5-4 mm. 



Type, in Bowditch collection, MCZ from Caracas, Venezuela; 

 probably several paratypes as some specimens beside the type are 

 labelled "Caracas". 



Other localities: Juan Mina, Canal Zone, collected by R. S. Shannon, 

 Sept. 2, 1923, Pecora, Panama, collected Feb. 10, 1945, by H. H. 

 Stage; Para Graso Mindi Dany Farm, Mindi, Panama, collected by 

 H. F. Dietz; Trinidad, collected by F. W. Urich and A. Busck; Cocoa 

 Estate, about 6 miles from LaBrea, Trinidad, collected by H. Morrison, 

 Oct. 18, 1918; Caracas, Venezuela; Mompos, Nare (on the Magdalena 

 River), Colombia. 



Remarks: In the Bowditch collection is a specimen from Caracas 

 bearing the label nigroguttata Baly and beneath that the label oblongo- 

 punctata Jacoby. It seems likely that this is the original Jacoby 

 specimen described by Jacoby from Caracas in 1882. Dr. Selman 

 writes that there are no specimens of Diabrotica oblongopunctata 

 Jacoby in the British Museum. There is on one specimen an old 

 Chevrolat green label with the name "Diabrotica oblongonotata Chev."
