J A C O B Y O N P H Y T O P H A G O U S C O L E O P T E R A . 603 much widened posteriorly, very finely punctate, the anterior portion to nearly the middle flavous, the rest, as well as the abdomen, bluish or greenish black. Also found on the banks of the Napo. 73. D I A B R O T I C A DISLOIDALIS, Baly. The specimens collected by Mr. Buckley agree very nearly with Dr. Baly's description, but show the following differences :-The broad transverse band of the elytra is light green instead of flavous ; the entire elytral margin and the apex are also of the former colour, which Baly does not mention; the black parts of the elytra are connected laterally by a narrow line. Not having the type to compare, I am unable to say whether m y insects are specifically different. An almost similarly coloured species is the following:- 74. D I A B R O T I C A T R A N S L U C I D A , sp. nov. Light-green ; head, breast, and legs black; elytra finely punctate, a transverse band at the base, and another broader one near the apex, black. Length 3 lines. Head impunctate, frontal tubercles obsolete; antennse half the length of the body, the second and third joints short, fourth joint longer than the two preceding united, black, three basal joints testaceous stained with piceous above, ninth and tenth joints flavous. Thorax subquadrate, very obsoletely bifoveolate at the disk; the latter impunctate, light green; scutellum black. Elytra sliglitly widened behind, finely punctured, of the same colour as the thorax ; a narrow transverse basal band deeply tridentate at its posterior margin, and a much wider one, rounded at its margins, close to the apex, black. Legs and breast black, the base of the femora light green. 75. D I A B R O T I C A VARIOLOSA, Jacoby, P. Z. S. 1878, p. 151. 76. D I A B R O T I C A PUNCTICOLLIS, Baly. 77. D I A B R O T I C A V E R R U C O S A , sp. nov. Testaceous ; head and six basal joints of the antennse black ; thorax fulvous, trifoveolate ; scutellum piceous; elytra rugose, punctate, and transversely wrinkled, metallic green, the lateral margin and the apex testaceous. Length 4 lines. Head longer than broad, foveolate between the eyes, impunctate. Antennse two thirds the length of the body, second joint short, third joint more than twice as long, the rest of nearly equal length, slender; the six basal joints black, underside of the first three and the terminal five joints flavous, extreme apex black. Thorax transverse, the sides distinctly sinuate near the base, deflexed, and longitudinally grooved parallel with the lateral margin, posterior angles tuberculate; surface impunctate, fulvous, with a deep oblique fovea at each side, and an oblique longitudinal central groove near the |
